DETAILS

WeaveHacks is back.
On October 11-12, 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. Whatever it looks like, we think you should build it.

We bring:

A killer office with ultrawide monitors & standing desks

Good food (breakfast, lunch & dinner)

Expert judges

A robot dog that yells at you

You bring:

Your ideas

A readiness to actually show up & crank out code

Good vibes

Will you make a research agent? A personal productivity assistant? A library for other agents to leverage? A new RL harness? What's the idea that's been on your mind? Whatever it is, no more excuses. This is your sign to build.

Theme tracks (not yet finalized):

Self-improving agents track. Build a system that gets better at what it does over time, in a useful or innovative way. Many ways you can do this, including but not limited to: Memory systems, automated tool creation, self-evaluation & reflection, new architectures, automated prompt iteration.

Reinforcement Learning track. How can you use RL to make your agents better?

Wildcard track. Build whatever insane thing your heart desires.

If you don't know, WeaveHacks is our AI Agent Hackathon series. Our first one was earlier this 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 1st WeaveHacks event: https://x.com/weights_biases/status/1944131338896126119



EXPECT:
$20k+ in prizes

Not one, but TWO Unitree G2 robot dogs

Tons of food, snacks, drinks

A handful of excellent sponsors, who will have onsite assistance for integrating their tools. Only a few though - no hours-long presentations at the start. We're here to hack.

Expert judges who can offer specific feedback
