  • One technical point raised is the use of “broken” GGUFs (model files) requiring specific command-line options for usability. The commenter advises waiting for the final merged version of GLM-4 32B for enhanced stability and compatibility, which would enable broader experimentation across different workflows and platforms.

  • Interest is expressed in using GLM-4 32B with LM Studio, indicating a demand for ecosystem support and integration for easier deployment and accessibility.

  • nsfw orpheus early v1 https://www.reddit.com/r/LocalLLaMA/comments/1k3wuud/nsfw_orpheus_early_v1/ (Score: 332, Comments: 66 https://www.reddit.com/r/LocalLLaMA/comments/1k3wuud/nsfw_orpheus_early_v1/): The post announces the early preview release of an NSFW-focused TTS voice model, mOrpheus_3B-1Base, available on Hugging Face (v1 https://huggingface.co/MrDragonFox/mOrpheus_3B-1Base_early_preview, v2 preview https://huggingface.co/MrDragonFox/mOrpheus_3B-1Base_early_preview-v1-8600). The model currently supports “common sounds” and generalizes well, albeit with only one voice in the preview checkpoints. The author notes considerable technical work on data cleaning and pipeline preparation to enable clean output, with the early models exhibiting convincing moans, laughter, and buildup to “sultry content.” One technical question from commenters raises the challenge of synthesizing complex emotional expressions (crying, angry screaming) and asks about the future ability of the model to handle such nuance, reflecting a broader technical gap in TTS emotional expressiveness.

  • MrAlienOverLord discusses the significant challenge of creating a reliable data pipeline for NSFW voice synthesis, emphasizing that cleaning and structuring data for emotionally rich TTS output was a major hurdle but ultimately enabled the generation of nuanced behaviors (e.g., moaning, laughing, and sultry buildup).

  • ffgg333 inquires about the model’s capacity for emotional diversity—specifically whether it can believably produce complex emotions like crying or angry screaming—and whether future iterations will tackle these harder-to-synthesize expressions. They also request information on supported emotional tags and seek access to demos on platforms like HuggingFace, highlighting practical interest in both technical capabilities and user interface.

  • BlipOnNobodysRadar requests usage instructions, indicating a typical need for accessible implementation guides or documentation for running early-stage, community-released TTS models.

  • Hunyuan open-sourced InstantCharacter - image generator with character-preserving capabilities from input image https://www.reddit.com/gallery/1k43htm (Score: 132, Comments: 6 https://www.reddit.com/r/LocalLLaMA/comments/1k43htm/hunyuan_opensourced_instantcharacter_image/): Tencent has open-sourced InstantCharacter—a tuning-free, one-shot image generation framework for character-preserving synthesis from a single reference image plus text prompt, aiming to balance consistency, image quality, and domain flexibility (project https://instantcharacter.github.io/, code https://github.com/Tencent/InstantCharacter, paper https://arxiv.org/abs/2504.12395). The method is compatible with the Flux pipeline, delivering high-fidelity, text-controllable outputs and targets per-instance generalization without retraining, positioning itself as a precision competitor to GPT-4o for image synthesis. Example results and evaluation demos are available on HuggingFace https://huggingface.co/spaces/InstantX/InstantCharacter. Expert users note the model achieves moderate clothing fidelity but struggles with facial identity and body shapes, implying limitations on realism (“no resemblance to the input face at all”). VRAM requirements are discussed, with estimates suggesting usage similar to other Flux-based models (~20–30GB). The model is criticized for poor handling of anime-style 2D images, which were not evidently covered in training.

  • Users report that InstantCharacter, run on hardware like A40 via RunPod, performs similarly to a slightly improved IPAdapter for character preservation, particularly noting its utility for clothing generation but significant shortcomings for facial matching and body type retention—“No resemblance to the input face at all. Doesn’t even take a body type into account.”

  • There are technical questions and speculation about the VRAM requirements of InstantCharacter, with some users estimating resource needs similar to base ‘flux dev’ models, in the range of 20-30GB VRAM, though no concrete figures are provided in the current discussion.

  • Performance appears to vary by training data: one user notes poor capability for anime-style 2D images, suggesting the lack of training on such data impacts generalization, particularly if non-photorealistic genres are important use cases.

  • A new TTS model capable of generating ultra-realistic dialogue https://github.com/nari-labs/dia (Score: 140, Comments: 40 https://www.reddit.com/r/LocalLLaMA/comments/1k4lmil/a_new_tts_model_capable_of_generating/): A new TTS model has been released, reportedly capable of producing ultra-realistic dialogue with significant expressive detail, as demonstrated in linked samples https://voca.ro/1oFebhjnkimo and emphasis via audio prompts https://voca.ro/1fQ6XXCOkiBI. Technical questions focus on whether the released weights correspond to the demoed model (possible distinction between smaller released and unreleased larger models), supported languages, emotion steering, voice cloning, prosody control (pauses, phonemization), and corpus/training regimen specifics. Commenters express skepticism about whether public weights match the showcased results and note limited documentation on functionalities (languages, emotion control, phoneme support, etc.), indicating that the README lacks important model capabilities and configuration details. [External Link Summary] Dia https://github.com/nari-labs/dia is a 1.6B parameter text-to-speech (TTS) model developed by Nari Labs that generates ultra-realistic multi-speaker dialogues directly from transcripts in a single pass. It supports audio conditioning for controlling emotion and tone, as well as synthesis of nonverbal sounds (e.g., laughter, coughing), and provides research-ready pretrained weights and code with a PyTorch backend (CUDA 12.6, pytorch 2.0+), requiring ~10GB VRAM for inference; quantized and CPU versions are planned. Dia is inspired by SoundStorm and Descript Audio Codec, with results and comparisons hosted on Hugging Face, and is released under the Apache 2.0 License, with clear restrictions against misuse for identity theft, deception, or illegality.

  • Commenters discuss the model’s demo samples, noting significant increases in audio realism when using the ‘audio prompt’ feature; the quality with this setting reportedly surpasses standard outputs, showcasing substantial advancements in expressive and nuanced synthesis (see link with audio prompt https://voca.ro/1fQ6XXCOkiBI).

  • Technical questions are raised regarding the model’s capabilities: support for multiple languages, degree and method of emotion steering, voice cloning procedures, insertion of pauses and phonemization capability, and details on required training data duration, implying the current documentation lacks key implementation and feature information.

  • Users compare output speed and naturalness, with one requesting options to slow down generated speech due to a rapid delivery reminiscent of legacy TTS systems (e.g., MicroMachines commercial), suggesting that prosody and pacing controls are critical for achieving ultra-realistic dialogue.

  1. HARDWARE AND VRAM CONSIDERATIONS FOR RUNNING LLMS

  • 24GB Arc GPU might still be on the way - less expensive alternative for a 3090/4090/7900XTX to run LLMs? https://videocardz.com/newz/sparkle-confirms-arc-battlemage-gpu-with-24gb-memory-slated-for-may-june (Score: 191, Comments: 77 https://www.reddit.com/r/LocalLLaMA/comments/1k49h0n/24gb_arc_gpu_might_still_be_on_the_way_less/): Rumors suggest Intel may release a 24GB Arc GPU, positioning it as a less expensive consumer-grade alternative for running LLMs (large language models), compared to high-end GPUs like the RTX 3090, 4090, or 7900XTX. Technical discussion points to strong Intel driver support, ongoing community integration with IPEX-LLM, and competitive VRAM, though there is no CUDA support and memory bandwidth is estimated to be about half of an RTX 3090, potentially aligning it more with an RTX 4060 in compute capability but with superior memory capacity. Commenters note the lack of CUDA as a significant limitation for LLM and ML workloads, though Vulkan and increased VRAM make it promising for non-CUDA-based applications. The card could compete with mid-range NVIDIA offerings for memory-constrained tasks, but bandwidth bottlenecks and actual performance parity are debated. [External Link Summary] The article reports that Sparkle has officially confirmed an Intel Arc “Battlemage” GPU equipped with 24GB of memory. This high-capacity graphics card is slated for release in the May–June timeframe. The announcement highlights a significant memory bump over current Arc models, indicating competitive positioning for demanding workloads or next-gen gaming.

  • Commenters note that a 24GB Arc GPU could provide a less expensive alternative for running large language models (LLMs), given its large VRAM capacity and integration efforts like IPEX-LLM, but the lack of CUDA support poses substantial compatibility limitations for many deep learning frameworks.

  • Performance-wise, the anticipated Arc GPU is compared to an RTX 4060, but with half the memory bandwidth of the RTX 3090. While the high VRAM is attractive for LLM workloads, there are concerns that bandwidth and general performance would lag behind higher-end Nvidia cards (e.g., 3090/4090) and even some upcoming mid-range cards (e.g., RTX 5060 Ti 16GB).

  • Recent updates highlight conflicting messaging from board partners (e.g., Sparkle Taiwan vs. Sparkle China) regarding the actual release and existence of the 24GB Arc GPU, reflecting ongoing uncertainty, which may affect planning for developers or researchers considering non-Nvidia hardware for LLM workloads.

  • What’s the best models available today to run on systems with 8 GB / 16 GB / 24 GB / 48 GB / 72 GB / 96 GB of VRAM today? https://www.reddit.com/r/LocalLLaMA/comments/1k4avlq/whats_the_best_models_available_today_to_run_on/ (Score: 171, Comments: 101 https://www.reddit.com/r/LocalLLaMA/comments/1k4avlq/whats_the_best_models_available_today_to_run_on/): The post requests up-to-date recommendations for the best local LLMs suitable for various VRAM capacities ranging from 8GB to 96GB, specifically focusing on practical deployment constraints. A detailed table in the comments suggests specific models for each VRAM range, e.g., Gemma 3 4B (8GB), Llama 3.1 8B (12GB), Gemma 3 27B/Qwen 2.5 32B (32GB), up to Command A 111B and Mistral Large (96GB), assuming use of 4-bit quantization for both weights and KV-cache with up to 48,000 token context. The post has been periodically updated with new model releases, such as QwQ 32B and Mistral Large, to reflect the fast-changing LLM ecosystem. One technically relevant comment challenges the framing, asking ‘Best for what?’, emphasizing that optimal choice depends on performance tradeoffs (e.g., speed, accuracy, specific task domain, etc.). Another meta-comment notes how frequently this question is asked, suggesting the need for regularly updated sticky guidance.

  • A table of model-VRAM pairings suggests optimal choices for various VRAM amounts, with notable examples including Gemma 3 4B for 8GB, Llama 3.1 8B for 12GB, and Command A 111B or Mistral Large for 96GB VRAM, all with configuration details like 48k token context and 4-bit quantization for both weights and KV cache. This highlights not only raw VRAM requirements but also practical quantization techniques that influence feasibility and performance.

  • Experiments with Gemma 3 12B QAT (quantization-aware training) quantizations show that even with only 12 GB VRAM, the model can run acceptably by offloading some layers to CPU, though with reduced speed. While not matching top cloud LLMs in perceived output quality, local models like this provide competitive results and illuminate hardware compromises for edge deployments.

  • On systems with 8GB VRAM, user experimentation finds models in the effective 9-13GB parameter range if quantized appropriately, such as Reka Flash 3 (Q3) for reasoning and Gemma 3 12B (Q4) for multimodal applications. Detailed TPS (tokens per second) and offload ratios are discussed for practical real-world throughput, noting that some large models (e.g., QWQ 32B or Mistral Small 3.1) are functionally usable but may be frustratingly slow at this VRAM tier.

  • Using KoboldCpp like its 1999 (noscript mode, Internet Explorer 6) https://v.redd.it/8hsjp4q1w3we1 (Score: 154, Comments: 15 https://www.reddit.com/r/LocalLLaMA/comments/1k43x1h/using_koboldcpp_like_its_1999_noscript_mode/): The post demonstrates using KoboldCpp’s “noscript mode” through Internet Explorer 6 (released in 2001) by accessing the web UI over a network, leveraging browser emulation (via oldweb.today http://oldweb.today) or a VM. The KoboldCpp Windows binary is not compatible with systems that can only run IE6; only the web interface is accessed remotely from modern hardware running the model. A top comment clarifies technical feasibility: noscript mode is broadly compatible with browsers from the last 30 years since it avoids modern scripting. Additionally, there is mention of someone running an extremely small (but largely impractical) language model on Pentium 3 hardware, illustrating the lower bound of LLM deployment. [External Link Summary] This Reddit thread discusses running KoboldCpp, a local large language model (LLM) UI, in “noscript” mode to support legacy browsers such as Internet Explorer 6 by disabling JavaScript. While the KoboldCpp Windows binary cannot execute directly on such old systems, its web interface is accessible from them via network. The noscript mode is valuable for retro-computing enthusiasts, those needing terminal browser support, or users concerned about JavaScript security, with the feature mainly added for fun and niche use cases by the developers. Original thread here. https://v.redd.it/8hsjp4q1w3we1

  • One commenter clarifies that the true technical constraint here is the frontend/browser: while Internet Explorer 6 (released in 2001) is featured, the UI in ‘noscript’ mode works on almost any browser from the past 30 years. The backend (KoboldCpp) runs on modern hardware, with old browsers connecting over the network; actual KoboldCpp binaries cannot run directly on legacy systems due to significant hardware and OS limitations.

  • A user recalls a technical experiment where a very minimal language model was run on Pentium III (P3) hardware. Although the model was tiny and functionally limited, the demonstration highlights the constraints and possibilities of running language models on vintage hardware, emphasizing the orders-of-magnitude difference in resource requirements compared to contemporary LLMs.

  1. OPEN SOURCE AI BUSINESS MODELS AND COMMUNITY SPECULATION

  • Why are so many companies putting so much investment into free open source AI? https://www.reddit.com/r/LocalLLaMA/comments/1k43g7a/why_are_so_many_companies_putting_so_much/ (Score: 164, Comments: 130 https://www.reddit.com/r/LocalLLaMA/comments/1k43g7a/why_are_so_many_companies_putting_so_much/): The post questions the business rationale behind heavy corporate investment into free/open-source AI, given proliferating alternatives that undercut commercial subscription models (citing OpenAI, Google, Llama.cpp, Unsloth, Mergekit). It highlights that firms like OpenAI provide generous free-tier access, further diminishing apparent revenue prospects, and wonders about ultimate strategic goals if no distinct performance lead emerges. Technical comments stress crowd-sourced innovation and rapid iteration as a key motivator: releasing open source models accelerates improvement and ecosystem building (e.g., major downstream contributions like Llama.cpp have made quantifiable cost savings industry-wide). Additionally, companies gain significant indirect value via publicity, research feedback, and ecosystem dominance. Monetization remains elusive for most, with GPU rental services being a notable exception thus far. Commentary underlines that much open AI investment is about collective progress and moat destruction, with many startups and tech leaders seeing open strategy as a necessary response to proprietary moves (e.g., OpenAI). The community’s cumulative research has broadly accelerated state of the art and redistributed value, but the long-term profitability question is unresolved, with speculation that direct profits are distant for all but infra providers.

  • Open source AI investment enables large-scale crowdsourcing for testing, development, and rapid innovation, as seen in projects like Llama.cpp, Unsloth, and Mergekit. The open release of models allows external researchers and enthusiasts to provide free feedback, discover optimizations, and share findings via open repositories and papers—generating massive aggregate cost savings and accelerating progress for those companies.

  • Meta’s shift post-Llama weights leak demonstrates a deliberate commoditization strategy: by open-sourcing strong models, they raise the ecosystem ‘floor,’ drive widespread Llama compatibility, and benefit from global research focused on their architecture. This approach is less about having the absolute best proprietary model and more about entrenching their ecosystem as a default, drawing clear parallels to OpenAI’s API lock-in and Anthropic’s MCP. Nation-state initiatives (e.g., Mistral in Europe, Falcon in Abu Dhabi) further diversify the motivations, often focused on regional technological independence.

  • Monetization is still elusive for most open-source model providers; companies offering GPU rental services are currently the main profit makers. Many subscriptions (even at large companies like OpenAI) have historically operated at a loss or are subsidized, sometimes using prompt data for further training or employing a strategy of undercutting prices to build market dominance, with plans for monetization post-competition shakeout.

  • Don’t Trust This Woman — She Keeps Lying https://www.reddit.com/r/LocalLLaMA/comments/1k4juhd/dont_trust_this_woman_she_keeps_lying/ (Score: 140, Comments: 40 https://www.reddit.com/r/LocalLLaMA/comments/1k4juhd/dont_trust_this_woman_she_keeps_lying/): The post centers on Bindu Reddy, CEO of Abacus.AI http://Abacus.AI and sponsor of LiveBench, allegedly spreading unverified rumors about major open-source LLM release timelines (notably for Qwen and Deepseek models). Screenshots show Qwen’s official team publicly denying claims about imminent releases, attributed to Reddy on social media. Conflicting release information is described as speculative and rapidly corrected by developers themselves, highlighting a persistent cycle of misinformation. Top commenters assert this behavior damages credibility in the open-source community, pointing out that repeated unsubstantiated leaks are motivated by attention rather than fact. They advocate ignoring such sources unless credible evidence or direct confirmation from model developers exists.

  • The top comment provides detailed allegations that Bindu Reddy, CEO of Abacus.AI http://Abacus.AI and sponsor of LiveBench, regularly announces false release dates for major open-source AI models (specifically citing “R2” and “Qwen 3”) without evidence. The commenter notes a repeating pattern: Reddy is contradicted by official model developers, deletes the inaccurate posts, and faces no repercussions, potentially spreading misinformation regarding the timelines and availability of significant LLM releases.

  1. OPENAI O3 RELEASE: COMMUNITY BENCHMARKS AND HALLUCINATION ISSUES

  • OpenAI’s o3 AI model scores lower on a benchmark than the company initially implied | TechCrunch https://techcrunch.com/2025/04/20/openais-o3-ai-model-scores-lower-on-a-benchmark-than-the-company-initially-implied/ (Score: 147, Comments: 25 https://www.reddit.com/r/OpenAI/comments/1k41jso/openais_o3_ai_model_scores_lower_on_a_benchmark/): The post discusses discrepancies in benchmark results for OpenAI’s ‘o3’ AI model on the FrontierMath benchmark. The original headline claims the public o3 model scored lower than OpenAI implied, but top commenters note the public release marginally outperforms earlier claims (improving from 8-9% to approximately 10%), while the much-publicized 25% result was achieved under extremely high test-time compute (~$3000/prompt per ARC AGI), not on the standard model. Issues around result reproducibility, benchmark subsets (frontiermath-2024-11-26 vs frontiermath-2025-02-28-private), and internal versus public scaffolding are highlighted as confounding factors. Commenters emphasize skepticism towards company benchmarks, stressing the need for independent, third-party benchmarks for accurate model assessment. One notes recent model releases seem underwhelming in real-world use.

  • The public release of OpenAI’s o3 model scores around 10% on a certain benchmark, which is slightly higher than the previously announced 8-9%. The much-publicized 25% score applied only under extremely high compute conditions (e.g., estimates of ~$3000 per prompt), making that result unrepresentative of actual user experience in the public version.

  • A critical point raised is the limited reliability of internal benchmarks from model developers like OpenAI; independent third party benchmarks are recommended, especially those evaluating across a broad set of real-world scenarios, for a more accurate measurement of the model’s true performance.

  • There’s a technical usability critique comparing OpenAI’s project/file limitations to Claude’s; specifically, OpenAI limits by file count (e.g., 20 small files), rather than token count, which constrains users who organize projects modularly even if the total data is minimal compared to Claude’s more generous limits.

  • Shocked at how much o3 is hallucinating. https://www.reddit.com/r/OpenAI/comments/1k4a9jj/shocked_at_how_much_o3_is_hallucinating/ (Score: 138, Comments: 54 https://www.reddit.com/r/OpenAI/comments/1k4a9jj/shocked_at_how_much_o3_is_hallucinating/): A user reports a significant increase in hallucination rates in GPT-4o (referred to as o3) compared to previous versions, particularly when the model is tasked with complex queries such as genealogy research involving sparse and ambiguous historical records. The model fabricated plausible-sounding but completely false citations and biographical details, only retracting them after persistent questioning. Commenters reference internal data (OpenAI systems card) indicating o3 has a 30% hallucination rate on the personQA benchmark, double that of GPT-3.5 (o1 at 15%), suggesting improved capabilities come at the cost of higher confident fabrication, potentially due to insufficient reinforcement against hallucination during post-training. Top comments highlight expert concern that o3 is a ‘Baron Munchausen’—more capable but more prone to elaborate falsehoods. Debate includes whether previous GPT models performed better on such tasks, and speculation that the RLHF phase does not sufficiently penalize plausible-sounding hallucinations.

  • A commenter cited the OpenAI system card, stating that GPT-4o (“o3”) has a hallucination rate of 30% on the PersonQA benchmark, double that of GPT-4 (“o1”) at 15%, meaning o3 is more accurate overall but also substantially more likely to hallucinate. This suggests that hallucinations are not sufficiently penalized in o3’s post-training phase, possibly by design or oversight.

  • Multiple users noted experiential issues with o3, including a specific instance in which the model invented new content while editing text and then insisted the fabricated content originated from the user’s documents. This highlights not only increased hallucination frequency but also a strong confidence in false outputs, making detection and correction cumbersome for end users.

  • There is speculation among technically proficient users that OpenAI may have released unfinished or insufficiently validated models, as o3 is repeatedly reported as underperforming in both output length and hallucination control compared to earlier versions. The consensus in rigorous use environments is that these regression issues are widespread and significant.

  • o3 is Brilliant… and Unusable https://www.reddit.com/r/OpenAI/comments/1k4bfy6/o3_is_brilliant_and_unusable/ (Score: 597, Comments: 159 https://www.reddit.com/r/OpenAI/comments/1k4bfy6/o3_is_brilliant_and_unusable/): The post discusses the o3 model, which shows remarkable promises in specialized domains like nutraceutical development, chemistry, and biology by generating novel and creative solutions. However, the poster highlights o3’s significant hallucination rate, where plausible-sounding yet inaccurate information is common — a recognized issue substantiated by OpenAI’s own reporting (system card PDF https://cdn.openai.com/pdf/2221c875-02dc-4789-800b-e7758f3722c1/o3-and-o4-mini-system-card.pdf), which lists o3’s PersonQA hallucination rate at 0.33 (vs. o1’s 0.16), even as its accuracy is only modestly higher (0.53 for o3, 0.47 for o1). This echoes broader concerns about RLHF (Reinforcement Learning from Human Feedback) tuning pushing models toward confident, logical, but sometimes incorrect synthesis. Commenters emphasize that this creative overreach is a novel QA/process issue, diverging from the anticipated AI trajectory; o3’s lateral reasoning yields impressive but unreliable content, necessitating human-like quality assurance but with a distinct fault heuristic. The proliferation of convincingly wrong output poses risks in automated knowledge work, with some users sharing anecdotes of AI fabricating plausible yet fictional academic content, highlighting the practical impact of model hallucinations.

  • OpenAI’s internal testing highlights the trade-off in o3: it achieves higher accuracy (0.53 on PersonQA) than o1 (0.47), but at the cost of doubling the hallucination rate (0.33 for o3 vs. 0.16 for o1), as detailed in their system card https://cdn.openai.com/pdf/2221c875-02dc-4789-800b-e7758f3722c1/o3-and-o4-mini-system-card.pdf. This raises questions about whether raw capability improvements outweigh reliability in applied settings.

  • Discussion suggests that the increased creativity and lateral thinking in o3 results in more frequent and convincing hallucinations, comparable to how an expert—when encouraged to be more conversational—may start making confident but incorrect off-the-cuff statements. This aligns with observations in other user-facing variants, where increased conversational ability often trades off with truthfulness or factual grounding.

  • A key implementation note is that o3-based models used for Deep Research do not exhibit the same hallucination problem, indicating that the issue may stem from the post-training process optimized for chatbot use (e.g., cost and engagement tuning), rather than the base model itself. This points to the importance of post-training alignment and deployment context in model behavior.

Notably, Skyreels-v2 produces video at 24fps, an improvement over competing models Wan and Vace (which run at 16fps), resulting in smoother motion and reduced artifacting, especially during rapid movement. Commenters express hope for rapid integration into other platforms (e.g., Kijai), highlighting community interest in broader adoption due to these technical improvements. [External Link Summary] A user reported generating a 30-second video using Skyreels-v2 on a single NVIDIA A100 GPU, noting the main subject remained stable and free of distortions. The discussion highlights that Skyreels-v2 renders at 24fps, providing smoother motion than previous models (like Wan and Vace, which output at 16fps), reducing common video generation artifacts such as limb or face disintegration. The post and comments indicate that such results are contingent on access to high-end hardware, though models may be quantized in the future for broader local deployment. Original post https://v.redd.it/nfyhj0xyx4we1
