Inference-Time Compute Hackathon

$50k top prize. $100k+ total. 24 hours to build.
Anthropic, Etched, Cognition, and Mercor are hosting a 24-hour hackathon! Build something that pushes the frontier of what AI can do and walk out with prize money, compute credits, and face time with industry founders.
This hackathon is in-person in San Francisco, and all participants are required to be present in-person for the entire hackathon.
This is a 24 hour hackathon with three tracks:
Agents: Multi-step systems that take a goal and execute. Tool use, planning, long horizons.
Real-Time and Interactive: Sub-second loops, live multimodal.
Talent Marketplace + Applied AI: Systems that judge capability of a person or a model. Autograders, preference ranking, rubrics, verified-skill signals, human-in-the-loop.
We'll provide 8x H100s per team, meals, snacks, and space for the full 24 hours.
Judges include founders from Etched, Cognition, and Mercor, plus special guests from well-known neolabs and neoclouds.
Apply as a pre-formed team of 2-4 or apply solo and we'll match you with teammates before the event.
Join us to begin building the next frontier. We'll see you there.
