Anthropic launches Claude Sonnet 5 with time-limited discounted pricing, improved agentic coding and benchmark performance, reduced misaligned behavior, and default cyber safeguards despite relatively weaker cybersecurity capability than top-tier models. New tools and apps include Google NotebookLM generating TikTok-style vertical video summaries of uploaded research and Google releasing Nano Banana 2 Lite, a faster, cheaper image generator available via API. Business and research updates span Etched’s push toward full-stack inference hardware with major funding and contracts, Baidu’s AI chip unit IPO ambitions, Agility Robotics’ SPAC plan, DeepSeek’s hiring expansion, and China’s open-source Longcat 2.0 MoE model with notable large-scale training and efficiency techniques alongside new long-horizon agent benchmarks.
