The Claude community is running buildathons around the world under the name **Fable 5.1 Build Days**. The events run from **11 to 25 September** in cities including Bhopal, Taipei and Tokyo.

According to the announcement you do not need a finished project to take part: bringing a problem or an idea is enough, and you can also simply come to see what people are building. Attendance is by registration.

The calendar is busy this month. After NVIDIA's event on 9 September and Copilot Day on 10 September, CoreWeave's Fully Connected conference opens on 29 September in San Francisco.
