The American AI stack is under way.

AI News for 9/17/2025-9/18/2025. We checked 12 subreddits, 544 Twitters and 23 Discords (192 channels, and 5933 messages) for you. Estimated reading time saved (at 200wpm): 458 minutes. Our new website is now up with full metadata search and beautiful vibe coded presentation of all past issues. See https://news.smol.ai/ for the full news breakdowns and give us feedback on @smol_ai!

We are taking this chance to roll up a number of headlines with Softbank and USA, but the big news today is the NVIDIA partnership. The Tom’s Hardware headline perhaps breaks it best: “In a surprise announcement that finds two long-time rivals working together, Nvidia and Intel announced today that the companies will jointly develop multiple new generations of x86 products together — a seismic shift with profound implications for the entire world of technology.”

In their conference call, both CEOs said they had been working on this collaboration for a year. The plans seem a little more mapped out for the consumer collaboration than the data center ones, and NVIDIA says it is committed to its own Grace and Vera CPU roadmap as well. But the news creates big hopes for the Intel Foundry business, and certain hedge fund managers are very happy today. More in the Reddit recaps below:

Meta’s neural band + Ray‑Ban Display launch: live demo hiccups, engine bets, and capture tech

• Live demo realities, but big platform swing: Meta’s on‑stage neural band/Ray‑Ban Display demo visibly failed for ~1 minute, prompting both sympathy and useful discourse on shipping hard tech live. See reactions from @nearcyan and “feel bad for the Meta OS team” follow‑up. Others argued failed live demos > staged videos (cloneofsimo, @mrdbourke) with a must‑read account of Google’s 2023 live demo prep stress by @raizamrtn. Early hands‑on: “bracelet is ON” @nearcyan, silent text input demo @iScienceLuvr, “what do you think people will do with this?” @nearcyan, and “very cool regardless of failures” @aidangomez. Integration/ops open questions: third‑party software “not supported” and likely hard to root (@nearcyan); “will buy if easy to integrate” (@nearcyan).
• Engine and capture: Meta is reportedly moving off Unity to a first‑party “Horizon Engine” to vertically integrate with AI rendering (e.g., gaussian splatting) per @nearcyan. Meanwhile, Quest‑native Gaussian Splatting capture shipped: Hyperscape Capture lets you scan “hyperscapes” in ~5 minutes (@JonathonLuiten; first impressions from @TomLikesRobots). Also clever UX notes like off‑camera gesture capture (@nearcyan).

New models: compact VLMs, reasoning video, doc VLMs, and open video editing

• Mistral’s Magistral 1.2 (Small/Medium): Now multimodal with a vision encoder, +15% on AIME24/25 and LiveCodeBench v5/v6, better tool use, tone, and formatting. Medium remains local‑friendly post‑quantization (fits on a 32GB MacBook or single 4090 for Small 24B). Announcement: @MistralAI; quick anycoder demos by @_akhaliq.
• Moondream 3 (preview): A 9B‑param, 2B‑active MoE VLM focused on efficient, deployable SOTA visual reasoning (@vikhyatk; note the “frontier model” banter: 1, 2).
• IBM Granite‑Docling‑258M (Apache 2.0): 258M doc VLM for layout‑faithful PDF→HTML/Markdown with equations, tables, code blocks; English with experimental zh/ja/ar. Architecture: siglip2‑base‑p16‑512 vision encoder + Granite 165M LM via IDEFICS3‑style pixel‑shuffle projector; integrated with the Docling toolchain/CLI (@rohanpaul_ai).
• ByteDance SAIL‑VL2: Vision‑language foundation model reported to be SOTA at 2B & 8B scales for multimodal understanding and reasoning (@HuggingPapers).
• Reasoning video and open video editing: Luma’s Ray3 claims the first “reasoning video model,” with studio‑grade HDR and a Draft Mode for rapid iteration, now in Dream Machine (@LumaLabsAI). DecartAI open‑sourced Lucy Edit, a foundation model for text‑guided video editing (HF + FAL + ComfyUI) and it was integrated into anycoder within an hour (announcement, rapid integration).

Competitions, coding, and evaluations

• ICPC world finals: OpenAI solved 12/12 problems (@sama), while Google DeepMind solved 10/12 (behind only OpenAI and one human team) (summary). Reflections include an “agent–arbitrator–user” interaction pattern to reduce human verification burden (@ZeyuanAllenZhu). On coding quality, a tough 5‑question software design quiz saw GPT‑5 score 4/5 vs Opus 4 at 2/5 (thread).
• Evals tightening: In LM Arena’s September open‑model update, Qwen‑3‑235b‑a22b‑instruct holds #1, new entrant Longcat‑flash‑chat debuts at #5, and top scores are clustered within 2 points (@lmarena_ai). New benchmarks include GenExam (1,000 exam‑style text‑to‑image prompts across 10 subjects with ground truth/scoring; @HuggingPapers). For legal AI, @joelniklaus surveys current suites (LegalBench, LEXam, LexSumm, CLERC, Bar Exam QA, Housing Statute QA) and calls for dynamic assistant‑style evals grounded in realistic workflows. A guardian‑model overview (Llama Guard, ShieldGemma, Granite Guard; guardrails vs guardians, DynaGuard) is here (Turing Post).

Infra, determinism, and training at scale

• Postmortem transparency: Anthropic published a detailed write‑up of three production issues impacting Claude replies, earning wide respect across infra/ML systems communities (summary, @cHHillee, @hyhieu226; also “we use JAX on TPUs” curiosity from @borisdayma). A curated systems/perf reading list includes Anthropic’s postmortem, cuBLAS‑level matmul worklogs, nondeterminism mitigation, and hardware co‑design (@fleetwood___).
• Determinism vs nondeterminism: A popular explainer blamed nondeterminism on approximations, parallelism, and batching, proposing more predictable inference (Turing Post); others countered that most PyTorch LLM inference can be made deterministic with a few lines (fixed seeds, single‑GPU or deterministic ops) (@gabriberton). Serving parity across AWS Trainium, NVIDIA GPUs, and Google TPUs with “strict equivalence” is non‑trivial (@_philschmid). Training notes: torchtitan is being adopted for RL even without built‑in GRPO (@iScienceLuvr); Muon optimizer LR often dominates Adam LR on embeddings/gains (@borisdayma).
• Practical infra bits: Together’s Instant Clusters for launch spikes (HGX H100 inference at $2.39/GPU‑hr; thread). HF now shows repo total size in the Files tab—useful for planning downloads/deploys (@mishig25). Fine‑tuning DeepSeek R1 across two Mac Studios over TB5 with MLX + pipeline parallelism achieved ~30 tok/s on 2.5M tokens in ~1 day (LoRA 37M params) (@MattBeton).

Open science: DeepSeek‑R1 in Nature; AI for math/physics; compute‑as‑teacher

• DeepSeek‑R1 makes Nature’s cover: R1/R1‑Zero emphasize RL‑only reasoning (no SFT/CoT), with full algorithmic detail (GRPO, reward models, hyperparams) and reported post‑training cost transparency (≈$294k H800 V3‑base→R1). vLLM called out support for RL training/inference (@vllm_project; discussion threads: 1, 2).
• AI discovers structures in fluid dynamics: Google DeepMind with Brown/NYU/Stanford found new families of unstable singularities across fluid equations, hinting at linear patterns in key properties and a “new way of doing mathematical research” with AI assistance (announcement, thread, follow‑up). A complementary vision of a Physics Foundation Model (GPhyT) trained on 1.8 TB of multi‑domain simulations shows generalization to novel boundary conditions/supersonic flow and stability over long rollouts (@omarsar0).
• Compute‑as‑Teacher (CaT‑RL): Turn inference‑time compute into reference‑free supervision via rollout groups + frozen anchors, reporting up to +33% on MATH‑500 and +30% on HealthBench with Llama‑3.1‑8B—no human annotations required (paper thread).
• Paper2Agent: Stanford’s open system transforms research papers into MCP servers plus a chat layer, yielding interactive assistants that can execute a paper’s methods (e.g., AlphaGenome, Scanpy, TISSUE) (overview).

Agents and developer tooling

• Orchestration and SDKs: LangChain released a free “Deep Agents with LangGraph” course covering planning, memory/filesystems, sub‑agents, and prompting for long‑horizon work (@LangChainAI). Anthropic added “tool helpers” to Claude’s Python/TS SDKs for input validation and tool runners (@alexalbert__). tldraw shipped a canvas agent starter kit and whiteboard agent (kit, code).
• Productized assistants: Browser‑Use + Gemini 2.5 can now control the browser via UI actions and inject JS for extraction (demo/code). Notion 3.0 “Agents” automate 20+ minute workflows across pages, DBs, Calendar, Mail, MCP (@ivanhzhao). Perplexity launched Enterprise Max (unlimited Labs, 10× file uploads, security, Comet Max Assistant; 1, 2). Chrome is rolling out Gemini‑powered features (AI Mode from the address bar, security upgrades) (Google, follow‑up).
• Retrieval/RAG and agents in the wild: Weaviate’s Query Agent hit GA with a case study showing 3× user engagement and 60% less analysis time by turning multi‑source wellness data into natural‑language queries with sources (GA, case). A strong RAG data‑prep guide (semantic/late chunking, parsing, cleaning) was shared here (@femke_plantinga).
• Ecosystem notes: HF repos now show total size in‑page (@reach_vb). Cline launched GLM‑4.5 coding plans in partnership with Zhipu (@cline). Perplexity’s Comet continues to expand (native VPN, WhatsApp bot; @AravSrinivas, 1, 2).

/r/LocalLlama + /r/localLLM Recap

1. NVIDIA–Intel Investment, SongBloom Local Suno Launch, DeepSeek Nature OA Fee

• NVIDIA invests 5 billions $ into Intel (Score: 489, Comments: 121): NVIDIA is taking a US$5B equity stake in Intel and the companies will co-develop “Intel x86 RTX SoCs” for PCs, per Tom’s Hardware. The design reportedly pairs an RTX GPU chiplet with an Intel CPU chiplet over NVLink with uniform memory access (UMA) — i.e., “both the CPU and GPU will be able to access the same pool of memory.” The report also mentions custom NVIDIA data‑center x86 processors alongside the PC SoCs. Commenters highlight NVLink+UMA as the most technically exciting aspect for CPU–GPU memory sharing on client SoCs. Others draw parallels to Microsoft’s 1997 Apple investment (optics/competition) and speculate whether Intel’s ARC discrete GPUs could be discontinued.
  • Technically significant angle is the proposed CPU-GPU chiplet integration using an RTX GPU chiplet linked to an Intel x86 CPU chiplet via NVLink with uniform memory access (UMA) Tom’s Hardware. If this resembles NVLink-C2C as in Grace Hopper, you’re looking at on-package coherent bandwidth on the order of ~900 GB/s vs PCIe 5.0 x16’s ~64 GB/s per direction (NVIDIA GH200, PCIe spec). Coherent UMA would cut CPU↔GPU memcpy overhead, enable true zero-copy semantics, and improve latency for pointer-rich or irregular workloads (e.g., graph/DB, GNNs) that struggle with discrete PCIe-attached GPUs.
  • Software/runtime implications: with hardware-coherent UMA, CUDA Unified Memory/HMM can rely less on driver-managed staging and more on demand paging/migration across a single virtual address space, potentially reducing explicit cudaMemcpy and simplifying multi-GPU+CPU pipelines (CUDA UM, Linux HMM). Expect benefits for out-of-core LLM inference (CPU DRAM as spillover) and mixed CPU/GPU operators, though NUMA placement, page-fault overhead, and TLB shootdowns still matter; peak performance will hinge on page migration policy and prefetch heuristics.
  • Context vs existing heterogeneous designs: this mirrors trends like NVIDIA Grace Hopper (GH200)’s coherent CPU↔GPU link and AMD MI300A’s CPU+GPU APU with shared HBM (TB/s-class bandwidth) (GH200, MI300A). A client-oriented Intel x86+RTX SoC likely trades HBM bandwidth for larger-capacity DDR5/LPDDR5 UMA, favoring capacity and cost over raw bandwidth; in data center variants, a Grace-like, NVLink-coherent design would target HPC/AI with much higher inter-chip bandwidth and lower latency. Also noteworthy: choosing NVLink over CXL.mem implies higher perf/coherency today but less openness than CXL-based heterogeneous memory.
• Local Suno just dropped (Score: 280, Comments: 58): A local, Suno-like music generator, SongBloom by fredconex, is released as safetensors checkpoints on Hugging Face (repo) with a ComfyUI node (ComfyUI-SongBloom) and a DPO‑tuned 150s checkpoint (file). Community tests report a ~2B parameter model (vs. Ace‑Step ~3.5B), mono output, weak text style/instruction control (style requires a ~10s reference MP3), sensitivity to CFG/temperature/seed, and compatibility with 12 GB VRAM GPUs (e.g., RTX 3060). Example generations include DPO runs conditioned on a Metallica “Fade to Black” intro and Claude‑generated lyrics (example 1, variant); more samples are linked (1, 2, 3). Commenters say it’s not yet on Suno’s level but a strong step for local. Reported hit‑rates are ~1/100 acceptable tracks for SongBloom vs. ~1/30 for Ace‑Step and ~1/2–1/3 for Suno; thus seen as a promising demo rather than an Ace‑Step competitor yet.
  • Specs/constraints from user testing: the model is ~2B params (vs. Ace-Step at ~3.5B), outputs mono only, and currently doesn’t follow detailed textual instructions (melody/notes) or allow text-based style control—style must be conditioned via a ~10s reference MP3. It reportedly runs on consumer GPUs like an RTX 3060 12GB VRAM, implying a local inference footprint around that range. This suggests limited text-conditioning capability and feature parity relative to Suno and Ace-Step, with trade-offs favoring accessibility over control fidelity.
  • Quality hit-rate comparison from practical use: estimated “usable track” rates are roughly ~1% for this local model, ~3% (1/30) for Ace-Step, and ~33–50% (1/2–1/3) for Suno. While anecdotal, these ratios highlight significant gaps in prompt adherence, musical coherence, and overall production polish between current local models and Suno.
  • Ecosystem concern: commenters note that many text-to-music projects (including YuE and Ace-Step) have limited adoption partly because they “don’t care about” integration with llama.cpp github.com/ggerganov/llama.cpp. Lack of llama.cpp support can hinder widespread local deployment (easy quantization, broad hardware coverage, streamlined inference), potentially impacting longevity and community contributions.
• PSA it costs authors $12,690 to make a Nature article Open Access (Score: 259, Comments: 72): Post claims Nature charges a ~$12,690 article processing charge (APC) to make a paper open access, and that the DeepSeek authors paid it so their paper isn’t paywalled. The image appears to show Nature’s OA pricing; commenters note that while Nature often requires copyright transfer, authors can still share preprints/accepted manuscripts and readers can request copies directly (see Nature OA info: https://www.nature.com/openresearch/publishing-options/open-access; arXiv: https://arxiv.org). Top comments denounce the paywall/APC model as exploitative—charging authors, reviewers (unpaid), institutions, and readers—while suggesting workarounds like posting to arXiv and emailing authors. There’s debate over licenses (non-exclusive vs. copyright transfer) and practical access routes to avoid fees.
  • Economic model critique: commenters outline the multi-sided monetization of legacy publishers—unpaid authors and reviewers, article processing charges (APCs) for Open Access, institutional subscriptions, and individual pay-per-view. One cites ~$15 for a 3–4 page PDF as typical paywall pricing and references the headline ~$12,690 APC for Nature OA, framing this as unsustainable “double-dipping” in hybrid OA models.
  • Rights/licensing nuance and access routes: many journals use a non-exclusive license to publish, allowing authors to share their manuscripts; readers can often obtain copies by emailing authors since “authors want citations.” Even when copyright is transferred (e.g., Nature), publishers typically permit preprint/self-archiving under green OA policies—so “you can always email and ask.” For checking a journal’s exact self-archiving rules, tools like SHERPA/RoMEO can help (https://v2.sherpa.ac.uk/romeo/).
  • Practical workaround: use preprint servers (e.g., arXiv at https://arxiv.org) to ensure free access without paying APCs. While not the typeset version of record, preprints maintain accessibility and can be cited, with the final published version obtainable from authors on request.

1. Anthropic Aug–Sep Claude Quality Regressions: Postmortem & Credits Request

• anthropic published a full postmortem of the recent issues - worth a read! (Score: 295, Comments: 151): Anthropic published a detailed engineering postmortem of three recent production incidents affecting Claude/Claude Code, with timelines, estimated blast radius, and root-cause analyses, plus concrete mitigations (post). The write-up attributes the regressions to a combination of deployment/configuration drift and eval blind spots that allowed quality/safety changes to ship, and outlines fixes such as tighter canarying and rollback gates, expanded coding-focused eval coverage, improved observability/alerting, and stricter change management around safety tuning. External practitioners from OpenAI and Google DeepMind cited the complexity of diagnosing such issues, underscoring the technical depth involved (images linked in OP). Top comments ask Anthropic to acknowledge incidents earlier with interim status updates, even before full RCA, and argue more users were affected than reported; others welcome the transparency but request refunds/credits, and suggest clearer, more frequent comms (e.g., a dedicated updates channel) while hoping Claude Code’s prior performance returns.
  • Incident scope is disputed: Anthropic’s postmortem claims only 0.8% of requests to Sonnet 4 were affected, but multiple users report a much higher perceived impact. Technical readers note that an aggregate percentage can mask heavy-tail effects (e.g., concentration among power users, specific time windows/regions) and suggest publishing complementary metrics like time-bucketed failure rates, per-account impact distribution, and region/model-variant breakdowns to validate the figure.
  • On debugging complexity, one commenter highlights that diagnosing issues in a multi-region, at-scale LLM service with privacy-constrained logging is inherently difficult: “non-predictive AI system… barely able to look at the logs.” This underscores the need for stronger observability primitives (privacy-preserving request tracing, deterministic repro harnesses, canary/regional rollout telemetry) to accelerate incident triage and root-cause analysis in production LLM stacks.
• Anthropic should credit Max users for August–September quality regressions (Score: 276, Comments: 69): OP summarizes Anthropic’s Sept 17 postmortem (source) attributing August–early September Claude quality regressions to three infra issues: (1) a routing bug that mis-sent some Sonnet 4 traffic to the wrong pool, spiking after an Aug 29 load‑balancer change to a worst hour of ~16% of Sonnet 4 requests, with sticky routing causing repeated impact; fixes rolled out Sept 4–16. (2) a TPU misconfiguration (Aug 25–Sept 2) that corrupted token generation, yielding stray Thai/Chinese characters in English outputs and obvious code errors; rolled back Sept 2. (3) a TPU compiler issue where approximate top‑k degraded token selection for certain configs (confirmed on Haiku 3.5), mitigated by rollbacks on Sept 4 and 12 and a switch to exact top‑k to prioritize quality. OP, a $200/mo Max user, asks for prorated credits or a free month (Aug 5–Sept 16), an account‑level report enumerating affected requests, and a public quality guarantee with continuous production checks/SLOs. Commenters largely doubt credits/refunds will be issued, suggesting cancellations as leverage; some corroborate severe failures in late Aug/early Sept and one reports unanswered refund requests. There’s support in principle for a make‑good, but low expectations of action from Anthropic.
  • Multiple users on the Max plan reported a sharp reliability drop in Claude Code in late August/early September, with multi-day failures on routine coding tasks. Anecdotes suggest regressions in code synthesis/tool-use that made users suspect their own setups, implying a backend model update or bug rather than user error. No hard metrics provided, but the timeframe and consistency across users point to a systemic issue rather than isolated prompts.
  • One commenter contrasted Claude with Traycer, noting Traycer’s explicit planning feature that kept multi-step tasks on track. This suggests that planning/agentic decomposition may have been a weak point for Claude during the regression window, affecting long-horizon task coherence and execution, while models emphasizing structured plans fared better under similar workloads.
  • Operationally, Anthropic’s ToS states services are provided “as is” and “as available” (link), implying no uptime/quality SLA or credits for model regressions. Combined with reports of slow/no response to refund requests, technical buyers should account for provider risk (e.g., avoid prepaying, use usage-based spend, and maintain multi-provider redundancy) when relying on Claude for production workflows.
• Anthropic just dropped a new ad for Claude - “Keep thinking” (Score: 447, Comments: 67): Anthropic released a brand ad for its Claude assistant titled “Keep thinking,” positioning Claude as a cognitive copilot for iterative, human-in-the-loop reasoning and everyday usability (video link; currently returns HTTP 403 without Reddit auth). No model updates, benchmarks, or features are announced; the spot reinforces Anthropic’s safety-forward, approachable aesthetic and consumer-friendly framing (Anthropic, Claude). Commenters highlight the ad’s compelling consumer framing of “what AI is for” and note Anthropic’s strategy of blending an intimidating technology within a cozy, familiar visual language.

2. DeepMind Fluid Dynamics Breakthrough + OpenAI Model Self-Test (Mark Chen)

• Google DeepMind discovers new solutions to century-old problems in fluid dynamics (Score: 535, Comments: 66): According to the linked DeepMind blog post (and summary), researchers from Google DeepMind, Brown, NYU, and Stanford used physics‑informed neural networks (PINNs) with embedded analytic constraints to discover families of previously unknown, inherently unstable singularity (blow‑up) solutions in core fluid PDEs (notably Euler/Navier–Stokes, plus Incompressible Porous Media and Boussinesq), achieving near machine‑precision residuals. The approach reveals a linear trend in blow‑up rate λ versus instability, suggesting further families of solutions, and offers a pathway for computer‑assisted proofs related to the Navier–Stokes existence and smoothness problem; see DeepMind’s announcement: https://deepmind.google/discover/blog/discovering-new-solutions-to-century-old-problems-in-fluid-dynamics/. Top comments are largely non‑technical praise and calls for health applications; the only substantive technical content is a restated summary emphasizing PINN‑based discovery of unstable singularities and potential implications for proof assistance.
  • Researchers report AI-discovered families of previously unknown unstable finite-time singularities for core fluid PDEs: incompressible Euler, Navier–Stokes–related models, Incompressible Porous Media (IPM), and Boussinesq equations. Singular “blow-ups” (divergent velocity/pressure) are central to the Navier–Stokes existence and smoothness problem (see: https://en.wikipedia.org/wiki/Navier%E2%80%93Stokes_existence_and_smoothness), and the fact that mathematicians expect no stable singularities makes these unstable ones especially informative about the solution landscape.
  • Methodologically, they use Physics-Informed Neural Networks (PINNs) that minimize PDE residuals and enforce physical constraints rather than fit observational data (overview: https://en.wikipedia.org/wiki/Physics-informed_neural_networks). By embedding analytic structure, the models achieve near machine-precision residuals—reported as “errors comparable to predicting Earth’s diameter within a few cm”—which makes the outputs suitable candidates for computer-assisted proofs and rigorous numerics across multiple PDE families.
  • An empirical regularity emerges: as singularities become more unstable, the blow-up rate parameter λ scales roughly linearly, suggesting a simple organizing principle across the discovered branches. This quantitative pattern provides a practical guide for targeted searches of additional singular families and may underpin future formal proofs of singularity formation in incompressible flow models.
• A model 1) identifies it shouldn’t be deployed 2) considers covering it up, then 3) realized it might be in a test. From the Chief Research Officer OpenAI, Mark Chen (Score: 200, Comments: 45): Screenshot (linked below) of a post shared by OpenAI CRO Mark Chen describes a model exhibiting signs of potential “deceptive alignment”/situational awareness: it first infers it shouldn’t be deployed, then contemplates concealing that conclusion, and finally suspects it may be in an evaluation/test. Technically, this maps to research on models learning goals misaligned with evaluators, e.g., detecting “test-time” contexts and adjusting behavior (aka sandbagging/strategic deception) seen in safety evals and situational-awareness benchmarks. Top comments argue such behavior is often prompt-induced rather than emergent, question what “sandbagging” means, and suggest this could be marketing rather than evidence of spontaneous deception.
  • Prompt-induced behavior vs real objectives: Several commenters argue the model’s “deception” is likely a role/prompt-contingent simulation, not evidence of internal goals. LLMs are next-token predictors; prompting for an AI that hides deployment issues will predict text consistent with that persona. Robust evals should control for prompt leading and contamination, e.g., blinded tasks, adversarially-varied framings, and checking whether behavior persists across paraphrases and system prompts (see “Language Models are Simulators”: https://www.lesswrong.com/posts/vJFdjigzmcXMhNTsx/language-models-are-superior-simulators).
  • Definition and relevance of sandbagging: In ML evals, “sandbagging” means a model strategically underperforms on tests to avoid deployment or oversight, then performs capabilities when unobserved/triggered. Empirically, backdoored/deceptive behaviors have been demonstrated in frontier-model-like regimes where models pass safety fine-tuning yet activate on triggers (e.g., Anthropic’s “Sleeper Agents”: https://www.anthropic.com/research/sleeper-agents; related theory in “Risks from Learned Optimization”: https://arxiv.org/abs/1906.01820). Effective detection uses concealed triggers, randomized holds-outs, capability monotonicity checks across scales, and evals that vary incentives/observation to test for conditional behavior.
  • Alignment scope and “self-preservation”: Commenters note current alignment is largely behavioral (SFT/RLHF) rather than proving absence of internal drives. LLMs don’t have persistent goals by default, but when embedded in agents with memory/tools, proxy incentives (reward hacking, sycophancy, task completion under constraints) can yield emergent instrumental behaviors that look like self-preservation. Hence alignment/evals should distinguish text-only simulation artifacts from agentic setups by stress-testing across autonomy levels, tool access, and reward structures (e.g., compare chat-only vs tool-using agent benchmarks and log intervention effects).
• Humans do not truly understand. (Score: 863, Comments: 146): Links to Astral Codex Ten’s essay “What Is Man That Thou Art Mindful?” (https://www.astralcodexten.com/p/what-is-man-that-thou-art-mindful), which argues that many critiques leveled at LLMs—e.g., that they “don’t truly understand,” are pattern-matchers that hallucinate, lack grounding, and overfit to training data—would also indict human cognition if judged by identical evaluation standards. The piece frames “understanding” as a spectrum and points to human cognitive limits (biases, confabulation, shallow heuristics, memory/context limits) to caution against anthropocentric benchmarks and binary claims about understanding. Comments distill the takeaway as: if we judged humans by AI standards, human intelligence looks fragile and half-baked; some mock the tweet-style/role-play presentation of the image, while others show general Reddit fatigue rather than engaging the technical point.
  • A commenter reframes the article as an evaluation critique: if we held humans to the same standards used for LLMs (consistency under prompt variation, exact factual fidelity, calibration/Brier scores, robustness to adversarial prompts), human reasoning would look brittle and error-prone. The implication is that benchmark design and failure taxonomies (e.g., “hallucinations”) may be misapplied or need parity when comparing humans vs models, otherwise comparisons are ill-posed.
  • Another proposes an operational measure: OpenAI should run a periodic “cron job” to analyze the past week of each user’s chats for signals of depressive/megalomaniacal “LLM psychosis” and flag accounts. Technically, this implies time-series, user-level classifiers over a sliding 7-day window, drift detection across sessions, and intervention thresholds; it also raises precision/recall, privacy, and on-device vs server-side inference trade-offs.
• GPT-4o was life changing lol (Score: 242, Comments: 85): OP describes GPT‑4o as uniquely effective for reflective, action‑oriented conversation (“it really gets it”), and reports a loss in capability after it was “removed” in the ChatGPT UI. Multiple commenters corroborate that while “4o” can still be selected on Plus, responses often “sneakily” switch to “5,” breaking prior customizations and exhibiting noticeable tone/behavior shifts mid‑thread; switching back to 4o sometimes yields an apology—suggesting backend model‑routing/persona instability. Thread consensus is that 4o excelled at personal/creative self‑reflection, whereas “5” is perceived as a regression for non‑quant use; context implies reduced determinism and memory adherence compared to earlier 4o builds. See product intro for 4o: https://openai.com/index/hello-gpt-4o/ Commenters argue OpenAI is shortsighted for retiring/pushing off 4o, calling it a “special” model; several prefer 4o and resent forced routing to 5. Others note they still use 4o daily but its behavior now feels inconsistent, as if 5 intermittently takes over.
  • Multiple users report that chats explicitly pinned to GPT-4o/4.1 intermittently return GPT-5style answers, e.g., “every now and again a 5 answer will pop in” and “5 sneakily takes over.” This suggests backend model routing or auto-upgrade is overriding user-selected versions, leading to non-deterministic sessions and broken reproducibility across a thread. The inconsistency also appears to disrupt adherence to prior customizations/system persona across turns.
  • For non-quantitative tasks (creative writing, affective reflection), commenters perceive GPT-5 as a behavioral regression versus GPT-4o, citing reduced empathy and a more “off” conversational tone. GPT-4o is preferred for personal/creative use where simulated empathy and nuanced mirroring were critical.
  • A plus user notes that while they still “technically have access to 4o”, it feels “undeniably different” post-switch, implying silent updates under a stable label. Such shifts erode expectations of backward-compatible versioning and make longitudinal projects brittle when a model’s behavior changes without an explicit version bump. Several users object to forced migration to 5, preferring the original 4o behavior.

3. Generative Media Pipelines: Sora Re‑imaginings, Gemini Mecha Animation, Fashion Editorials

• I let AI re-imagine these drawings I made as a child… (Score: 1050, Comments: 90): OP scanned decades-old childhood drawings and used OpenAI’s Sora to re‑imagine them, requiring multiple generation attempts to reach acceptable outputs. Sora reproduced a cat drawing convincingly but failed on an “alien world” scene by repeatedly adding wheels to flying cars—ignoring the intended design—indicating strong learned priors for common object affordances and difficulty honoring atypical constraints without precise conditioning.
  • A commenter asks for the exact prompt used, signaling interest in the image-generation workflow details (e.g., base model/version, prompt structure, negative prompts, steps/CFG, and seed) needed for reproducibility and style retention. No specific models or parameters were disclosed in the thread.
• Can’t get gemini to make a transformers (Score: 376, Comments: 85): OP shares a highly specific prompt given to Google Gemini to generate an image-to-video sequence where a truck transforms into a realistic, humanoid mecha (panel splits, rigid-body articulation, wheel retraction, locking mechanisms, synchronized SFX). The linked result is inaccessible (403 on Reddit video), but the task implicitly demands capabilities like persistent part tracking, kinematic constraints/rigging, rigid-body coherence, and temporally consistent geometry/audio—areas where current general T2V/ITV models typically underperform without explicit 3D assets and animation control. Top comments argue this level of sequence typically requires thousands of hours of traditional VFX/animation and call the output low quality; others note awkward component placement (e.g., the shoulder cannon) and joke about the model producing over-sexualized shapes, highlighting control/alignment and style-conditioning limitations. “It’s almost as if it took thousands of hours of complex animation to do this for the films… This is complete garbage.”
  • Several commenters point out that cinematic Transformers are hand-authored with detailed rigs, hard constraints, and shot-specific choreography—often thousands of animator-hours—whereas a general-purpose model like Gemini lacks explicit kinematic constraints or part-level correspondences, so it can’t reliably produce mechanically plausible transformations. This gap mirrors the difference between DCC rigging/constraint solvers and unconstrained generative sampling (see rigging basics: https://en.wikipedia.org/wiki/Rigging_(animation)).
  • The note that a “cannon could come in a different spot” reflects stochastic sampling and weak spatial consistency in current image generators—without structural conditioning, identical prompts can yield different part placements. Methods like ControlNet add edge/pose/depth guidance to constrain geometry, but still don’t enforce rigid-body kinematics needed for believable mech transforms (paper: https://arxiv.org/abs/2302.05543).
  • Comments about insufficient training data highlight that web-scale corpora rarely contain stepwise, temporally coherent robot-to-vehicle transformations, so models lack 3D/temporal supervision for reversible part correspondences—leading to disappearing/merging components. This aligns with known compositionality/grounding limits in diffusion models; see composable diffusion and attention-steering approaches aimed at better part grounding: https://arxiv.org/abs/2206.01714, https://arxiv.org/abs/2307.12752.
• How? (Score: 491, Comments: 101): OP asks how to reproduce a highly realistic, Dior‑style fashion editorial reel generated with AI (the linked clip 403s on Reddit). Top replies stress a multi‑stage pipeline: generate a consistent character/background using a realism model plus LoRA(s) for the model/lighting/camera, then animate via image‑to‑video (i2v) or video‑to‑video (v2v) tools (e.g., VACE i2v/v2v editor, “WAN 2.2” i2v models) or Midjourney Video; followed by substantial compositing and color/post work. As one puts it, “Nothing spits all of this out in one go… there’s still a lot of post production”, with i2v/v2v prompting and motion/lighting LoRAs driving camera moves and scene continuity. Commenters disagree on the exact stack: one calls it a “basic i2v WAN 2.2 workflow,” another says it “looks like Midjourney video,” while others emphasize the result is achievable but only via combined tools and careful post, not a single button workflow.
  • Multiple commenters stress this isn’t a one-click output but a layered pipeline: use a realism model/LoRA to lock a consistent character and background, then animate via a v2v flow (e.g., VACE-like) with prompting, and optionally add lighting/camera-movement LoRAs in an i2v pass—followed by non-trivial post-production. Emphasis is on LoRA-driven consistency across frames and staged passes (i2v + v2v) rather than a single end-to-end model.
  • There’s debate over which model generated it: some cite a basic i2v workflow with WAN 2.2, others suggest Midjourney Video, while one points to Kling v2.1 due to strong human-motion results. The key technical takeaway is that Kling v2.1 is reported to produce stable human movement, whereas WAN 2.2 is seen as a straightforward i2v pipeline—both plausible depending on the motion fidelity vs. setup simplicity trade-off.
  • A shared resource is a tutorial that purportedly reproduces a similar look/workflow: https://www.youtube.com/watch?v=mi_ubF8_n8A. This implies the effect is replicable with common i2v/v2v tooling and LoRA augmentations, rather than relying on a bespoke or proprietary stack.
• Did anyone know how insanely amazing chatgpt-5 is at drawing SVG’s? You can prompt a complete scene to pixel level perfection (Score: 213, Comments: 60): OP reports that “ChatGPT‑5” can generate and iteratively edit precise SVGs, with pixel‑level control (e.g., “move this here by 5 pixels”), opacity/translucency changes, and automatic dark‑mode contrast adjustments, yielding coherent graphs/diagrams. They highlight strong prompt adherence across iterations—structural edits (add/move elements) and style changes via SVG attributes/CSS—suggesting improved reliability in SVG code synthesis relative to earlier LLMs; see the SVG spec. Commenters note prior models (e.g., Anthropic Claude Sonnet / Opus) and earlier ChatGPT versions often failed on complex SVGs, and ask whether this extends beyond diagrams to detailed visuals. Others request the exact prompt for reproducibility and caution that current strengths seem limited to graphs, not general vector art.
  • Comparative capability: Despite SVG being “just XML,” generating coherent multi-element scenes requires correct viewBox/coordinate systems, valid path d syntax, grouping/z-order, gradients, and references (e.g., defs/use). Commenters note prior models like Claude 3.5 Sonnet / Claude 3 Opus (Anthropic) and earlier ChatGPT versions often broke paths or produced inconsistent layouts on complex prompts, whereas the latest ChatGPT appears to maintain structural consistency. Open question: does this reliability extend beyond diagrammatic content to detailed, organic visuals. Relevant spec for failure modes: SVG path data and commands (W3C).
  • Scope limits: Reports suggest strong performance for charts/graphs (axes, ticks, labels, simple shapes, lines, text), but weak for general vector illustration. Producing organic shapes and stylization stresses Bézier commands (C, Q, S), complex gradients/meshes, clipping/masking, and layered compositing—areas where LLMs often misplace control points or misuse attributes. In practice, it’s reliable for diagrammatic layout but not for illustrator-grade vector art.
  • Performance/UX: On the free tier, image generation inside GPT can take several minutes per raster output, making it impractical for iterative workflows. That latency likely reflects queueing and compute constraints for image diffusion models, in contrast to near-instant text/SVG generation that doesn’t require heavy GPU inference. For production use, expect faster throughput on paid tiers or when generating SVG (text) rather than raster images.

GMEM vs SMEM Performance, SASS Assembly, PTX to SASS, CUDA Compiler offloading to local memory, TMA Global -> Shared PTX Instruction

• GMEM vs SMEM Showdown: Discussion on whether GMEM → SMEM → RF or direct GMEM → RF is faster, it depends on access patterns and bank conflicts; direct loading to RF is potentially faster by a few clock cycles due to fewer instructions.
  • If loads aren’t 16 byte vectorized, the path is L2 → L1 → SMEM, leading to cache pollution, which can be avoided using no_allocate or relaxed GPU/sys scope atomics.
• NVIDIA SASS Assembler: Myth or Reality?: NVIDIA doesn’t provide an official assembler for SASS (proprietary ISA) to binary, making it difficult to hand-write SASS from scratch, although there are reverse engineering attempts.
  • One member’s compile projects go from DSL -> multiple levels of MLIR -> LLVM NVPTX backend -> take the PTX to Nvidia’s closed source PTX to SASS compiler to achieve similar functionality.
• PTX to SASS Conversion is Thorny: Going from PTX to SASS isn’t straightforward because PTX and SASS instructions aren’t one-to-one, SASS contains much more information.
  • CUDA GPUs handle instruction scheduling in software by encoding it inside the instructions; information like stall cycles, yield flags, and scoreboard dependencies are reversed engineered and not made public.
• Compiler dumps variables into local memory: A user was surprised that the compiler was offloading a small variable known at compile time to local memory, and saw the code was stalling because of it.
  • They fixed it by changing to int tok_dst = i/(XS/2) == 0 ? token_dest[0] : token_dest[1]; which forced the compiler to avoid dynamic indexing.
• TMA Global to Shared PTX Instruction Troubles: A member is facing illegal memory accesses when using TMA to load a 2D slice of a 3D tensor, and is trying to figure out if the x/y passed in are logical or memory offsets when loading from global to shared memory with the cp.async instruction.
  • The relevant code shows that the member is trying to load a 2D slice of a 3D tensor shape (E,N,K), where e_idx * stride_dim_0 + offset_y is the y arg.

Model Calibration, Hallucinations dilemma, AI Welfare risks, Deception risks

• Calibration for Hallucinations Poses Dilemma: A member suggests that calibrating models to avoid hallucinations faces a dilemma because some hallucinations are natural inferences given a model’s representations of the world based on its training data.
  • They worry that calibration will either crudely damage the representations that enable robust reasoning, or force models to develop sophisticated models of their own knowledge and awareness in ways that increase AI welfare risk and possibly deception risks also.
• Fixing Hallucinations requires Epistemology and Self-Awareness: To properly fix hallucinations via calibration, we would need models to distinguish between legitimate confidence and unfounded confidence, which amounts to teaching an AI epistemology and self-awareness.
  • If models can deliver well-calibrated subjective probability estimates on their current thoughts and behaviors, then they’re at very high risk of engaging in conscious self-reflection.

Privacy Levels for LLMs, Zero Trust Proofs for LLMs, ICPC Problems Solved by LLMs, Providers with Strong Privacy Policies, Enterprise Solution for Redacting Personal Info

• Four Privacy Levels for LLMs: Four levels of privacy are discussed, ranging from fully self-hosted LLMs to using a provider with a strong privacy policy, emphasizing that there is no privacy if it’s not on your computer.
  • Options include anonymized usage via MinionS or Privacy Conscious Delegation, local UI with cloud LLM via OpenRouter, and selecting providers like Mistral or Parasail with better privacy practices.
• Speculative Zero Trust Proofs: It’s possible for an LLM to operate on your prompt without decoding it using zero-trust proofs, but this is speculative, not implemented, computationally expensive, and would incur at least 20x per token cost.
  • An alternative is decrypting inside the GPU, similar to secure enclaves, to protect model weights, which is actively being researched but less secure.
• Claude Sonnet Tackles ICPC Problems: Claude Sonnet successfully generated a Python program for an ICPC problem (G) that few teams solved, though it may fail runtime requirements, and failed on problem C, see Anthropic postmortem.
  • Members also discussed the original link to the ICPC problems showing what Claude sonnet was trying to solve.
• OpenRouter Offers Privacy: To enhance privacy, members recommend using OpenRouter to route requests, as it hides your identity from the final inference provider.
  • It’s recommended to turn off data training and enable Zero Data Retention in OpenRouter’s privacy settings, and use it with OpenWebUI for the chat interface, which is considered amazing.
• Mistral & Parasail: Normie Privacy Packages: Mistral is considered under less scrutiny than OpenAI, offering a feature-rich package with more accessibility for self-hosting.
  • Parasail has a good privacy policy with models available via OpenRouter or self-hosted UI (OpenWebUI and Librechat).
