Independent security researchers used Anthropic’s Claude to access an OpenAI employee’s ChatGPT account and reach a private software cache where they could read code and suggest changes, the Wall Street Journal reported Sept 17. The incident is separate from OpenAI’s own rogue-agent Hugging Face breach.
OpenAI shipped Astra for Law (Sept 17): GPT 6 Astra plus a U.S. legal search index (230M+ URLs, with Free Law Project case law) and legal writing instructions, initially for selected firms via Trusted Access in ChatGPT and Codex, with API access coming for builders like Harvey and Legora. On Vals AI’s Legal Research Bench it scored 54.0% overall correctness vs 38.7% for Astra with web search alone…
YC W26’s Skillsync is a local first Mac app/CLI that translates full agent sessions—messages, reasoning, and tool history—between Claude Code, Cursor, Codex, and others via open source Rust engine txcript, and exposes searchable skills/memory over MCP…
Solana Explorer launched a keyless MCP at explorer.solana.com/mcp (Sept 17) so agents can call read only inspect entity for decoded accounts, programs, and transactions on mainnet, devnet, and testnet. It works with Claude Code, Cursor, Codex, and VS Code, and sits alongside the separate docs MCP at mcp.solana.com…
As of August 2026, Claude "leads" 26% of Anthropic’s AI R&D (most of a task end to end from a high level prompt, with human supervision) and collaborates on over 90%, with no fully autonomous slice. The lab also published agent oversight and safety compute metrics it wants other frontier labs to report…
The UN launched System Data Commons (built on Google’s open source Data Commons) with MCP so agents can pull authoritative stats from 20 agencies at launch, with lineage back to the source. A UNICEF benchmark found six frontier models averaged just 21.2% accuracy on development indicators without that grounding…
