## Evidence

Verbatim from https://allenai.org/blog/astabrief:

> We built AstaBrief 8B , a model that turns a research question and retrieved literature excerpts into a cited report. AstaBrief is available in Asta’s Generate a report feature today as Fast mode alongside Claude-powered Thinking mode, and we’re also open-sourcing it and the training data so others can study, reproduce, and build on our approach.
