MCP -> Agentic AI Foundation, Mistral Devstral 2
OpenAI Engineering sees a significant collaborative milestone with the launch of the Agentic AI Foundation under the Linux Foundation, uniting projects from Anthropic, OpenAI, and Block. Mistral released Devstral 2, a coding model with 123B parameters and open weights, offering a cost-effective alternative to Sonnet 4.3 and competitive performance against DeepSeek v3.2. The new Mistral Vibe CLI supports agentic coding workflows with rapid ecosystem integration. Alibaba introduced Soft Adaptive Policy Optimization (SAPO) for reinforcement learning tuning, improving stability and performance in Qwen3-VL across multiple tasks. Research highlights include the importance of data decontamination in RL and ongoing discussions on MoE RL stability and reward hacking mitigation.
