DETAILS

WeaveHacks is back (With Redis, Vercel, Browserbase, Daily, Marimo & Google Cloud)
On Jan 31-Feb 1, come to the Weights & Biases SF office (no online component, sorry) to have the most fun building agents you'll have this year. This time, we're highlighting self-improving agents.

Agent capabilities have advanced a lot over the last year. The next wave of agents will be different though - they'll be upgrading themselves. This can mean better memory systems, new forms of RL & fine-tuning, new ways of dynamic tool creation, self improving loops like Ralph, GasTown etc. Agents that run while you sleep. Whatever it looks like, we think you should build it!

We bring:

A killer office with ultrawide monitors & standing desks

Great food & drinks (breakfast, lunch & dinner)

Expert judges

A robot dog that yells at you

You bring:

Your ideas

A readiness to actually show up & craIf you don't know, WeaveHacks is our AI Agent Hackathon series. Our first one was last year in which over 200 builders came from across the country to network, build, & deploy agents. Due to popular demand, we are doing another one & this time we will have even bigger prizes.

Here is a peek at what to expect, from our 2nd WeaveHacks event: https://x.com/wandb/status/1981434285879157116/video/1

APPLYING TO PARTICIPATE
Apply on Luma! Participants in our past hackathons get an instant acceptance. Beyond that, we prioritize hackers who have some kind of project they've built that they can point to (it doesn't need to be polished at all). Github or Devpost links are fine. No specific experience is required.

Note that we will likely hit max capacity on registrations before the event, so apply early, & mark yourself as going / not going as soon as you know (so you're not taking a slot from someone else).

Come ready to build agents
