Open Source AI Week 2026 | Open Weight Debate Night
The Open Weight Debate is where Open Source AI Week gets into discussion, opinions, and fun. We're bringing together sharp minds who actually like to debate and discuss with each other and putting them on stage to hash it out live. Real arguments, real examples, and real dialogue about the questions that matter most to the future of open source AI. We're hosting at GitHub HQ where the developer minds are at.
