Security researchers used Anthropic's Claude to exploit a bug in OpenAI's Discourse forum, gaining access to its private "monorepo" code repository via a bug bounty program. OpenAI also launched Astra for Law, a specialized legal AI tool built on GPT-6 Astra with a dedicated case law index for select firms. Meanwhile, Anthropic redesigned Claude Projects to support parallel agent threads and established a Bay Area wet lab to accelerate AI-driven drug discovery and biological research.
