About the event
Come plug in and supercharge at our premiere CoreWeave hackathon! If you’ve had an idea for an autonomous loop that’s been burning away at you, this heavily-resourced hack is for you to make it happen. Experience everything you’ve come to love about Weights & Biases WeaveHacks– this time with the full CoreWeave stack (Weave, ARIA, marimo, and much more).
Join us at our SF office (this is an in-person event) to have the most fun building loops you'll have this year. This round is all about the loop: building agents that cycle through reasoning and action, catching their own mistakes, and pushing towards more powerful results at each pass.
Agent capabilities have advanced enormously over the last year — even by their own doing: better memory systems, new forms of RL and fine-tuning, dynamic tool creation, and self-improving loops. This time we observe, evaluate, track, document, and self-improve agent iterations while we play with a robot dog and humanoid!
Hackers get Fully Connected
Attendees have the chance to attend our Fully Connected conference September 29-October 1 (each ticket ~$1k in value), where a final CoreWeave Hacks award will be presented for the “Most Production-Ready” submission.
Criteria for any non-winning attendee to get a ticket will be announced at the event. Once building starts, find out more from a CoreWeave representative.
The Best Loop Design winners on 9/13 get tickets and stage time at Fully Connected.
The winning team gets a stage demo on the final day, presenting their project in front of AI leadership. Build like it matters; the work can carry straight from the hackathon floor onto that stage!
You will have a second chance to win 2 weeks after CoreWeave Hacks, at our Fully Connected conference!
We bring

You bring
Your ideasA readiness to actually show up & crank out codeGood vibes
Will you build a dojo where agents train themselves? A hall of mirrors where agents grade their own reflections? A memory palace agents keep rewriting? A forge where agents hammer out their own tools? A loop that learns from its own scars? A colony of agents keeping each other honest? However you've been dreaming about closing the loop on self-improving agents — no more excuses. This is your sign to build.
If you don't know us: CoreWeave Hacks is our AI agent hackathon series (formerly "WeaveHacks"). Our first ones drew over 200 builders from across the country to network, build, and deploy agents. Due to popular demand, the series continues with new features.
