Anthropic's most advanced model ever, released only to select cybersecurity companies via Project Glasswing. Not publicly available due to safety review — but it exists and it outperforms everything else.
A full desktop app (macOS & Windows) for knowledge workers — think Claude Code but for everyone. Includes computer use, plugin marketplace, and role-based admin controls for teams.
Set up coding automations that run on a schedule, via API call, or triggered by GitHub events — without an active session. The redesigned desktop app includes an integrated terminal and diff viewer.
Claude now creates live charts and diagrams directly in chat. Memory from chat history is now free for all users — not just paid plans. Also confirmed: Claude will never show ads.
