The recent AI news highlights the Karpathy interview as a major event, alongside significant discussions on reasoning improvements without reinforcement learning, with test-time sampling achieving GRPO-level performance. Critiques on context window marketing reveal effective limits near 64K tokens, with Claude Haiku 4.5 showing competitive reasoning speed. GPT-5 struggles with advanced math benchmarks, and data quality issues termed "Brain Rot" affect model reasoning and safety. In agent frameworks, Anthropic Skills enable modular coding workflows, OpenAI Codex IDE extensions enhance developer productivity, and HuggingChat Omni introduces meta-routing across 100+ open models using Arch-Router-1.5B. LangChain and LlamaIndex advance graph-first agent infrastructure, while Google Gemini integrates with Google Maps for real-world grounding.
