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 Google's Gemma as an example.

You might be using open-source software right now without even knowing it. 👀 In celebration of Hacktoberfest, Rosendo breaks down what open source is and why you should care on this week's Prompt Pad. 🎃

Tune in tomorrow!

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?

Hacktoberfest Week 2: Side Hustle is live! 🟣 Build something someone would actually pay for 🟣 Tell us why open-source and open-models matter for the project 🟣 $2,550 in prizes across 18 winners dev.to/devteam/join...
