This year, we focused on building with open-weight models and open source AI, at Fests around the world and online. Our hope was to bring the community together and WOW, so many of you showed up!

🎃 Hacktoberfest by the numbers

• 115,385 people took part, at in-person Fests and online, from Global Hack Week to DEV Challenges
• 500+ in-person Fests in 70+ countries and territories (our original goal was 300!)
• 50+ livestreams from the community, partners, and Global Hack Week programming

🏆 Meet the DEV Challenge winners

We ran five challenges this month, with one prompt and a new theme each time. Go say congrats to the winners and see what they built:
