Come plug in & 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, & 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 & action, catching their own mistakes, & 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 & fine-tuning, dynamic tool creation, & self-improving loops. This time we observe, evaluate, track, document, & self-improve agent iterations while we play with a robot dog & 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 & 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

A killer office with ultrawide monitors & standing desks

Great food & drinks (breakfast, lunch, & dinner)

Expert judges

A humanoid that hands out stickers & dancing robot dog

The full CoreWeave SaaS stack for agents

A chance to attend Fully Connected - & a stage demo for the winners

A media team capturing the event (winner video, coverage, & interviews)

Whimsy

You bring

Your ideas

A readiness to actually show up & crank out code

Good 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, & deploy agents. Due to popular demand, the series continues with new features.

Applying to participate

Apply on Luma. We prioritize hackers who have some kind of project they've built & can point to (it doesn't need to be polished at all) - GitHub or Devpost links are fine. No specific experience required.

Given the WeaveHacks 4 demand, we will be selective with a cap at 200. We'll likely hit max capacity before the event, so apply early, & mark yourself going / not going as soon as you know so you're not holding a slot. Please do what you can to have your entire team (all members) sign up ASAP, as we likely will not have space for new team members to join at the door.

What's holding you back? This is your sign to build.
