🚀 Claude Fable 5.1 Build Day

​Claude Fable 5.1 just shipped, and we're putting it to work. 🔥 The Claude Community Build Day lands in San Francisco on Saturday, September 19, at Tenki Cloud's new offices. A full day building on Anthropic's most advanced model, days after launch. ⚡

​💡 What it's about

​Building with Fable 5.1. Four hours of continuous, hands on keyboard building with the new model, followed by demos, winners and networking. Part of the official Claude Community Build Day series.

​🎁 What you get

​💳 $100 USD in API credits per attendee to build during the event and keep going after.
🌎 Global reach: your build and the recap go into the roll-up Anthropic sends to the entire Ambassador network.
📣 A direct line to product: feedback from the room reaches Anthropic's product and model teams.
