We tested 22 agent classes—more *kinds* than other benchmarks

🤖AgentBaselines makes them reusable, incl. our SOTA science agents: github.com/allenai/agent-baselines

📊Leaderboard: huggingface.co/spaces/allenai/asta-bench-leaderboard

🛠️AstaBench is the first to provide reproducible (date-limited) large-scale search tools—plus a full scientific research environment for agents.

📊Our leaderboard highlights agents that use these tools, enabling more controlled measurement of *AI*. (We measure LLM costs too.)

AstaBench with abstract measurement icons

Agent benchmarks don't measure true *AI* advances

We built one that's hard & trustworthy:
👉 AstaBench tests agents w/ *standardized tools* on 2400+ scientific research problems
👉 SOTA results across 22 agent *classes*
👉 AgentBaselines agents suite
