The project has accumulated 22,323 stars with 46 added today, and claims usage by OpenAI and Anthropic.
ByteDance released DeerFlow 2.0, an open-source agent harness built on LangGraph/LangChain that orchestrates parallel sub-agents with sandboxed Docker environments, progressive skill-loading, and persistent memory for complex workflows. Anthropic filed two lawsuits against the U.S. Pentagon contesting a supply-chain risk blacklist tied to its refusal to remove guardrails preventing Claude's use in autonomous weapons and domestic surveillance, with potential multi-billion dollar revenue impact. Google released Gemini Embedding 2, a multimodal embedding model unifying text, images, video, audio, and PDFs in a single vector space, succeeding the text-only predecessor. Meta acquired Moltbook, an agent-to-agent social platform built around the OpenClaw framework, while OpenAI hired OpenClaw's creator and acquired AI security testing platform Promptfoo.
OpenAI announced the acquisition of Promptfoo, an AI security platform focused on identifying and remediating vulnerabilities in AI systems during development. The acquisition signals OpenAI's intent to deepen its enterprise security capabilities. Promptfoo has been widely used by developers to red-team and evaluate LLM applications for safety and reliability issues.
