Arc Prize Foundation

The ARC Prize Foundation is a nonprofit advancing open artificial general intelligence research through scientifically rigorous benchmarks and competitive prizes. Its ARC-AGI benchmark series measures fluid intelligence on tasks that are easy for humans but hard for AI, and its ARC-AGI-3 Interactive Reasoning Benchmark exposes a public REST API (three.arcprize.org) plus an open-source Python toolkit and SDK for building agents that play, score, and generalize across novel game environments. The Foundation runs the ARC Prize competitions in partnership with Kaggle, with participation from OpenAI, Google, xAI, Anthropic, and NIST.

Arc Prize Foundation publishes 3 APIs on the APIs.io network: Commands API, Games API, and Scorecards API. Tagged areas include Company, Artificial Intelligence, AGI, Benchmarks, and Agents.

Arc Prize Foundation’s developer surface includes authentication, changelog, documentation, API reference, quickstart, engineering blog, signup flow, and 15 more developer resources.
