Asta isn’t just another chatbot; it’s a full stack for building and evaluating AI agents that can actually assist researchers. It ships with an open research assistant that reads papers, synthesizes evidence and even cites its sources. AstaBench’s 2,400‑problem benchmark suite gives us a reproducible way to compare agents on real multi‑step science tasks like literature review and code execution. The project also includes open‑source agents, APIs and language models tuned for research, plus access to a 200 M‑paper corpus.

In a world full of closed, untested agent tools, Asta is refreshing and gives developers all the components they need to build their own trustworthy science agents.
