About Aster

Aster is the first autonomous research lab, thousands of AI research agents orchestrated in parallel toward a single goal. We're on a mission to automate open-ended research: research that defines its own problems before it can answer them. The future doesn't wait to be defined by benchmarks. Neither do we.
