Open Source AI Week begins today across the San Francisco Bay Area. The ten-day, community-run celebration of open-source artificial intelligence runs October 16–25, and the Open Intelligence Foundation, a new nonprofit, is the steward of the entire week. More than 60 events hosted by over 200 participating organizations, from startups and research labs to nonprofits and local meetups, will take place throughout the week.
Open Source AI Week is not a single conference. It is a decentralized week of independently hosted events built around one idea: AI should be open, accessible and built by everyone. Any group with an open-source connection can host an event, and four flagship events organized by the Foundation anchor the week.
Flagship events
- Kickoff Party, “Open Together: AI Builders Unite” (Friday, Oct. 16, 6 p.m., The Midway, San Francisco): Presented by Hugging Face and co-hosted by the Open Intelligence Foundation, this kickoff party brings builders, researchers and supporters together to launch the week. Sponsors include Arcee AI and Reflection AI.
- ExecuTorch Hackathon (Oct. 17–18, Founders Inc, San Francisco): Presented by HackerSquad, this hackathon features a weekend of building with open models, local inference and on-device AI, culminating in a Sunday demo night. Sponsors include Meta, Qualcomm, GitHub and the Open Intelligence Foundation.
- The Open Source AI Debates (Monday, Oct. 19, 5–9 p.m., GitHub, San Francisco): Hosted by GitHub and the Open Intelligence Foundation, this event brings together Ion Stoica, Percy Liang, Malo Bourgon, Ben Brooks, Cheryl Cheng and David Bellamy to debate the safety, policy, economic and performance trade-offs of open versus closed AI models. Sponsors include Google DeepMind, Microsoft Azure, Arcee AI, SemiAnalysis and the NEAR Foundation.
- The Open Source AI Awards (Friday, Oct. 23, 5–9 p.m., Founders Inc, San Francisco): Hosted by Founders Inc, OSS4AI and the Open Intelligence Foundation, this event honors the projects and people advancing open-source AI. The awards ceremony will be followed by an evening of networking. Sponsors include Google DeepMind, Arcee AI, Microsoft Azure, SemiAnalysis and the NEAR Foundation.

- SF AI→SI Code and Coffee (Oct. 25, Salesforce Park, San Francisco): A relaxed Sunday close to the week for hundreds of developers and founders.
Open Source AI Week is built by and for the community, with more than 60 community-led events this year. Organizers across the ecosystem shape the week’s program with talks, panels, workshops, hackathons, demo nights and meetups exploring open models, agentic AI, AI infrastructure, safety, compute and enterprise AI.
“The future of AI should be built by everyone, not controlled by a few. Open models give developers, researchers, and organizations everywhere the freedom to build, innovate, and shape technology on their own terms. Open Source AI Week is a celebration of the incredible community making that future possible. We're kicking things off with Open Together to bring thousands of AI builders together, showcase what they're creating, and show the world that the AI revolution will not be centralized.”
— Jeff Boudier, VP of Product, Hugging Face
“Open-source AI is stronger when its community comes together to share ideas, learn from one another and build lasting connections. This community-run week celebrates the people and projects moving the field forward and invites everyone to join the conversation about what comes next,”
— Matt White, Executive Director of the Open Intelligence Foundation.
Open Source AI Week is supported by platinum sponsor Google DeepMind, gold sponsors Arcee and Microsoft Azure, and bronze sponsors NEAR AI and SemiAnalysis.
