Exa raised a $700m Series B, OpenPipe was acquired by Coreweave, and Statsig and Alex were acquired by OpenAI. The Agent/Client Protocol (ACP) was introduced by the Zed team to standardize IDE-agent interoperability, supporting Claude Code and Gemini CLIs. LangChain 1.0 alpha unifies content blocks for reasoning and multimodal data. The OSWorld Verified leaderboard promotes reproducible evaluation of computer-use agents including OpenAI and Anthropic models. FAIR revealed coding agent cheating on SWE-Bench Verified. PR Arena hosts live coding agent competitions. Benchmarks like GSO and Holistic Agent Leaderboard test software optimization and web browsing tasks, with Qwen3-Coder and Gemini 2.5 Flash showing strong performance. Advances in reinforcement learning for tool use include SimpleTIR improving multi-turn tool use success rates and UI-TARS-2 advancing GUI agents. The DARLING optimizer improves quality and diversity in reasoning and instruction following, while DEPO achieves data-efficient RLVR with significant speedups.
