Your AI and this story

  • GPT-6 Astra6 days after its cutoff
  • Claude Opus 5.5In its training data
  • Gemini 4 Hydrogen36 days after its cutoff
  • Grok 4.7In its training data

It is after the cutoff of GPT-6 Astra and Gemini 4 Hydrogen, and can be in the training data of Claude Opus 5.5 and Grok 4.7.

Key facts

  • San Francisco May 6 (plus indie/founder day), London May 19, Tokyo June 10
  • Managed Agents: ‘dreaming’ (agents rehearse on past data), outcomes, multi-agent orchestration
  • Claude Code five-hour rate limits doubled across Pro, Max, Team, Enterprise; peak-hour throttle lifted
  • Reported SpaceX Colossus 1 compute partnership: >220,000 NVIDIA GPUs, >300 MW (third-party recap, not verified from primary source)
  • Later (X reply, ~July 10, 2026, per Outlook Business): asked whether SpaceXAI could hurt Anthropic by ending the Colossus 1 lease (~$1.25B/month through May 2029, 90 days’ notice, per SpaceX’s S-1 via Business Insider), Musk wrote ‘I was clearly wrong about Anthropic. They are obviously currently the leader in AI’ and ‘I would never cut them off in a way that hurt them badly, even as a competitor’; the quote resurfaced in Stocktwits headlines on Oct 17, 2026

What happened

Other May launches around the conference, per a third-party timeline: a Skills marketplace (~600 skills, May 1), Claude Platform on AWS GA (May 11), the Claude Code /goal command (May 12), and the acquisition of Stainless (SDK tooling, May 18).

Why it matters

The conference marked Anthropic’s shift toward hosted agents and showed how much compute it was lining up, including from Elon Musk’s SpaceX/xAI infrastructure.
