Hacktoberfest wraps up this week, but what you learned doesn't have to. 🎃 Keep building, share what you made, and help the next builder get started. There's still time to join: hacktoberfest.com

Keep building on your Hacktoberfest projects. That project you started at a Hack Day doesn't have to end when October does. Swap in a new open-weight model, add a feature, or turn your demo into something you actually use every day.

Share what you made. Push your code to a public repo, write up what worked (and what didn't), or post a quick demo video. Open source runs on people sharing what they've learned.

Pass it on. Answer a question in a community forum, help a friend run their first model locally, or bring someone new to your next hackathon.

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.

What actually happens when you send a request to an LLM? Gateway → tokenizer → router → queue → prefill → decode → streamed back to you, one token at a time. I'm tracing the whole trip tomorrow at Hacktoberfest 2026. ⚡ Thu, Oct 22 online @ 10am PT / 1pm ET link below 👇

Open source is built on a simple idea: what you learn, you share. 🎃 What's one thing you've learned from contributing that could help the next first-timer?
