San Francisco | Claude Build Day

Anthropic-run Claude Community Build Day at 590 Howard St in SoMa, San Francisco, a full day for builders to ship projects on the newly released Fable 5.1 model.

Sat, Sep 19, 9:00 AMSoMa, San Francisco, CA

Why it matters

Attendees get early hands-on time with a just-launched model, present demos, and their feedback is routed directly to Anthropic's product and model teams.

The tokenmaxxing angle

Each attendee gets $100 in Claude API credits and must arrive with Claude Code and Claude Desktop installed, making the day a live test of output per credit spent on a new model.

From the organizers

Page states attendees receive $100 USD in API credits, need an Anthropic console org set up beforehand, and choose one of three tracks: Delight, Breakthrough, or Everyday.
