Anthropic has officially released Claude 4 with two variants: Claude Opus 4, a high-capability model for complex tasks priced at $15/$75 per million tokens, and Claude Sonnet 4, optimized for efficient everyday use. The release emphasizes instruction following and extended work sessions up to 7 hours. Community discussions highlight concerns about token pricing, token accounting transparency, and calls for open-sourcing Claude 3.5 Sonnet weights to support local model development. The news also covers Claude Code GA, new Agent Capabilities API, and various livestreams and reports detailing these updates. There is notable debate around sliding window attention and advanced inference techniques for local deployment.

o3 model achieved a gold medal at the 2024 IOI and ranks in the 99.8 percentile on Codeforces, outperforming most humans with reinforcement learning (RL) methods proving superior to inductive bias approaches. Nvidia's DeepSeek-R1 autonomously generates GPU kernels that surpass some expert-engineered kernels, showcasing simple yet effective AI-driven optimization. OpenAI updated o1 and o3-mini models to support file and image uploads in ChatGPT and released DeepResearch, a powerful research assistant based on the o3 model with RL for deep chain-of-thought reasoning. Ollama introduced OpenThinker models fine-tuned from Qwen2.5, outperforming some DeepSeek-R1 distillation models. ElevenLabs grew into a $3.3 billion company specializing in AI voice synthesis without open-sourcing their technology. Research highlights include Sakana AI Labs' TAID knowledge distillation method receiving a Spotlight at ICLR 2025, and Apple's work on scaling laws for mixture-of-experts (MoEs). The importance of open-source AI for scientific discovery was also emphasized.
