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.

    Introducing Aster — a major breakthrough for research intelligence. Aster isn’t a single agent. It is the first autonomous lab orchestrating thousands of research agents in parallel. We pointed Aster towards ProteinGym, a benchmark that measures how accurately models predict Show more Quote Y Combinator @ycombinator · Jun 13 Aster (@asterailabs) is building the autonomous research lab. They run thousands of AI agents in parallel to achieve 1000x speedups in autonomous research. Their lab just set a world record on ProteinGym in 30 minutes—and now they're automating open-ended research. Congrats on 0:10 / 1:10
