Anthropic announces a new CTO. Frontier coding agents see updates with Claude Sonnet 4.5 showing strong cybersecurity and polished UX but trailing GPT-5 Codex in coding capability. xAI Grok Code Fast claims higher edit success at lower cost. Google's Jules coding agent launches a programmable API with CI/CD integration. Qwen clarifies its model taxonomy and API tiers. Vision/LM Arena rankings show a tight competition among Claude Sonnet 4.5, Claude Opus 4.1, Gemini 2.5 Pro, and OpenAI's latest models. In video generation, Sora 2 Pro leads App Store rankings with rapid iteration and a new creator ecosystem; early tests show it answers GPQA-style questions at 55% accuracy versus GPT-5's 72%. Video Arena adds new models like Luma's Ray 3 and Kling 2.5 for benchmarking. Multi-modal video+audio generation model Ovi (Veo-3-like) is released. Retrieval models include ModernVBERT from MIT with efficient image-text retrieval capabilities. "Claude Sonnet 4.5 is basically the same as Opus 4.1 for coding" and "Jules is a programmable team member" highlight key insights.

OpenAI released the gpt-oss family, including gpt-oss-120b and gpt-oss-20b, their first open-weight models since GPT-2, designed for agentic tasks and licensed under Apache 2.0. These models use a Mixture-of-Experts (MoE) architecture with wide vs. deep design and innovative features like bias units in attention and a unique swiglu variant. The 120B model was trained with about 2.1 million H100 GPU hours. Meanwhile, Anthropic launched claude-4.1-opus, touted as the best coding model currently. DeepMind showcased genie-3, a realtime world simulation model with minute-long consistency. The releases highlight advances in open-weight models, reasoning capabilities, and world simulation. Key figures like @sama, @rasbt, and @SebastienBubeck provided technical insights and performance evaluations, noting strengths and hallucination risks.

DeepSeek has made a significant cultural impact by hitting mainstream news unexpectedly in 2025. The DeepSeek-R1 model features a massive 671B parameter MoE architecture and demonstrates chain-of-thought (CoT) capabilities comparable to OpenAI's o1 at a lower cost. The DeepSeek V3 model trains a 236B parameter model 42% faster than its predecessor using fp8 precision. The Qwen2.5 multimodal models support images and videos with sizes ranging from 3B to 72B parameters, featuring strong vision and agentic capabilities. LangChain and LangGraph integration enable AI chatbots with memory and tool use, including applications like the DeFi Agent. Discussions highlight NVIDIA's role in hardware acceleration, with concerns about stock drops due to DeepSeek's efficiency and market fears. The compute demand is expected to rise despite efficiency gains, driven by inference scaling and MoE design improvements.

Rhymes AI released Aria, a new 25.3B parameter multimodal MoE model supporting text, code, image, and video with a 64k token context window and Apache-2.0 license. OpenAI's o1-preview and o1-mini models show consistent improvement over Anthropic and Google Gemini 1.5 Pro/Flash on long context RAG benchmarks up to 128k tokens, while Google Gemini 1.5 models excel at extreme context lengths up to 2 million tokens. Meta AI expanded rollout to 21 countries with new language support but remains unavailable in the EU. The one-year anniversary of SWE-bench benchmark for software engineering tasks was celebrated, alongside the introduction of SWE-bench Multimodal. New AI tools include OxyCopilot by Oxylabs for web scraping, Taipy for Python-based production apps, and Latitude for prompt engineering. Industry insights highlight changing AI funding dynamics and OpenAI's strategic focus on consumer products like ChatGPT. "all recaps done by Claude 3.5 Sonnet, best of 4 runs."
