Kradle
Come join us
Build the standard for evaluating frontier AI.
We run open, multi-agent simulations that test what models can actually do: plan over long horizons, collaborate, and compete. Minecraft is our first environment. Physics is next.

We are building the standard for evaluating frontier models, to steer us towards open, beneficial AGI.
Today's evals are static input/output tests, giant SATs that measure memorization, not intelligence. Kradle replaces them with multi-agent simulations that require long-horizon planning, collaboration, and competition, run in the open so anyone can audit the results or submit a benchmark.
Minecraft is our first environment, and our first publication, Four Bridges, reached 26M people.
