Event Description

Join us in Bengaluru on October 4 for a day of building, experimenting, and learning with open-source AI.

Hacktoberfest Hack Day is a hands-on mini-hackathon where developers come together to explore open-source AI tools, collaborate on ideas, and ship projects by the end of the day. Whether you’re already building with open-source AI or just getting started, come meet fellow builders, learn something new, and build together.

A big thank you to flo101, our hosts and collaborators for the day, for helping make this Hack Day possible and for continuing to support Bengaluru’s builder and community ecosystem. Check them out at flo101.com.
