xAI launched Grok 4.1, achieving a #1 rank on the LM Arena Text Leaderboard with an Elo score of 1483, showing improvements in creative writing and anti-hallucination. OpenAI's GPT-5.1 "Thinking" demonstrates efficiency gains with ~60% less "thinking" on easy queries and strong ARC-AGI performance. Google DeepMind released WeatherNext 2, an ensemble generative model that is 8× faster and more accurate for global weather forecasts, integrated into multiple Google products. Sakana AI raised ¥20B ($135M) in Series B funding at a $2.63B valuation to focus on efficient AI for resource-constrained enterprise applications in Japan. New evaluations highlight tradeoffs between hallucination and knowledge accuracy across models including Claude 4.1 Opus and Anthropic models.

OpenAI's Evals team released GDPval, a comprehensive evaluation benchmark covering 1,320 tasks across 44 predominantly digital occupations, assessing AI models against human experts with 14 years average experience. Early results show Claude 4.1 Opus outperforming human experts in most categories and GPT-5 high trailing behind, with projections that GPTnext could match human performance by mid-2026. The benchmark is positioned as a key metric for policymakers and labor impact forecasting. Additionally, Artificial Analysis reported improvements in Gemini 2.5 Flash/Flash-Lite and DeepSeek V3.1 Terminus models, alongside new speech-to-text benchmarks (AA-WER) highlighting leaders like Google Chirp 2 and NVIDIA Canary Qwen2.5B. Agentic AI advances include Kimi OK Computer, an OS-like agent with extended tool capabilities and new vendor verification tools.

OpenAI launched GPT-5, a unified system featuring a fast main model and a deeper thinking model with a real-time router, supporting up to 400K context length and aggressive pricing that reclaims the Pareto Frontier of Intelligence. The rollout includes variants like gpt-5-mini and gpt-5-nano with significant cost reductions, and integrations with products such as ChatGPT, Cursor AI, JetBrains AI Assistant, Microsoft Copilot, Notion AI, and Perplexity AI. Benchmarks show GPT-5 performing strongly in coding and long-context reasoning, roughly matching Claude 4.1 Sonnet/Opus on SWE-bench Verified. The launch was accompanied by a GPT-5 prompting cookbook and notable community discussions on pricing and performance.

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.
