Roughly 24 hours ago we concluded the Berlin @OpenAIDevs DevDay Hackathon!
Over 245 people joined us on two floors in the @circuit_ber startup house.
Within 8 hours participants had the chance to build amazing projects, no matter if technical or non technical.
In the end, 73 projects were submitted across the Developer and Founder/GTM tracks.
3 teams per track won a lot of API & Codex credits. As well as 10 tickets to the DevDay Berlin tomorrow!
For me it honestly was a huge amount of stress and hassle!
I straight up ran around the location from 8 am to 7pm and tried to put out as many fires as possible.
We had a lot of typical hackathon things go wrong as usual haha
Wifi was spotty and going down, credit distribution was flaky but in the end we managed to persevere.
I was lucky to have an amazing team of supporters on location that was pitching in and honestly handling so much work that I could've never done without them.
This day showed how important real life interaction still is and how much I personally still can learn about making this experience enjoyable for everyone.
Thank you to the brilliant ambassadors who were there:
@DFinsterwalder (from Göppingen)
@mrlesk (from Vienna)
@laraavci_ (from Munich)
@janpfrenger (from Frankfurt)
@artur_wala (from Warsaw)
as well as the wonderful extra supporters:
@_Ms_Stacy, Eleni Koukidou, Jérémy Grandillon
and tons of other people who helped out on the event
Special thank you also to the absolute legendary OpenAI folks who showed up:
@paw_lean: for making this event possible in the first place and being a beam of inspiration for everyone on the event
@reach_vb: for starting this community program and also showing up at this event!
and @TilmanResch for dropping by for a few minutes and being the OpenAI GTM legend he is
And thank you to @rhiannon_io who unfortunately couldn't make it to the event but helped immensely to actually let this come together and deliver goodies for so many people from the US to Europe.
Thank you to @Qu1nn_web3, Kushal Singh and the rest of the location staff for managing the different event fires with me and making sure the whole event is well caffeinated.
And thank you to @Son_of_a_Pigeon, the best event photographer ever, for the most insane and awe-inspiring pictures from the day.
To even greater hackathons and more insane projects
Max
PS:
Excited for the OpenAI DevDay Berlin tomorrow!

The Decisions API is now generally available!
To celebrate, I had Codex reimagine a very important app… 🌭

I'll be talking about Castellan, an RTS I built with Codex and Claude Code, where the players are Codex and Claude themselves.

Huge thanks to our Codex Ambassadors and local hosts for bringing their communities together. 💜
Ignacio is such an important part of our community. Our events wouldn’t be the same without his hard work and energy. Thank you for everything you do, and for sharing what you learn with the rest of us! #DevDayCommunity
Less than 24 hours before my talk at OpenAI DevDay Exchange Santiago, I had to rewrite it.
It was already done. Then @aastroza asked me to change the focus and reframe it. I started to panic.
Then I remembered I have a Dot.
I spent about 4 hours chatting with it, from rough ideas to the final script. That's the version I gave on stage.
The talk was about how I actually use Dots every day: turning ideas into action, connecting my tools, and getting more time for what I enjoy.
My favorite example: I built a connector so my Dot can see my university courses in Canvas.
My main message: AI shouldn't replace you. It should help you go further and make the process more fun.
Huge thanks to @paw_lean for making this event possible, and to @aastroza for organizing it. I'm really happy I got to help him make it happen.
Video coming soon for anyone who missed it.

The ultimate LLM benchmark: Chilean Spanish.
80% of AI models fail to recognize Chilean Spanish and insist on speaking like an Argentine

I asked my dot to figure out where I should eat at LAX before flying back to Santiago. It chose chicken & waffles.
Guys, we achieved AGI. 🫡
This week has been absolutely wild, and I’ll share more about it soon. One of the highlights was finally meeting @jxnlco in person and getting the chance to thank him for how much his writing and work on Instructor have inspired me over the years.
The week ended with @_pilliin_ and @fforres welcoming me into their home. I’m incredibly grateful for their hospitality, ¡se pasaron!
And somehow, sitting around a table sharing stories, it felt like the Chile we grew up in was still right there with us ❤️
