Open weights and open source aren't quite the same thing. 🔓 To celebrate the final week of Hacktoberfest, Rosendo breaks down open-weight models on this week's Prompt Pad, using @googlegemma as an example.

Was fun mentoring folks and being a judge at Hacktoberfest Hack Day Bengaluru. Loved chatting with people building with open source AI and helping them figure out how their projects could work for end customers. 🥂

Wrapping up an epic Hacktoberfest 2026 at GCU From pitching disaster response solutions on stage to scoring that sweet MLH swag, the open-source energy was absolutely unmatched. Huge shoutout to the Codenix Club and everyone who brought the heat to Hack Day.

Hacktoberfest starts today, and it isn't counting PRs this year. Good. AI made PRs cheap to write. Maintainer review time didn't get any cheaper. Ship one PR you can explain line by line. Which repo are you eyeing? 👇 #Hacktoberfest #OpenSource

1/7 I joined Hacktoberfest 2026 today and attended “Introduction to Gemma with Google DeepMind” with @IanBallantyne and @SwiftAlphaOne . I went in thinking I’d learn about another AI model. Instead, I started thinking about a much bigger question: Where should AI actually live?

Hacktoberfest stopped counting pull requests this year. The PR counter is GONE. This year it's about open source AI: > write your first skill > build your own open source agent > fine-tune an open model DEV's weekend challenge opens tonight, 7 PM PDT. Due Sunday, 11:59 PM. Then 4 weeks of open source AI challenges from Monday. Still want to ship a real PR this weekend? 5 MCP servers on my board have good first issues open: > MarkItDown, 4 > Slack MCP, 3 > dbt, Kubernetes and Docker, 1 each Good weekend to write your first skill 🔥
