Open-sourcing AstaBrief, the fast report-generation model in Asta

Automated excerpt

To do that, we tested whether a small, open model trained specifically for scientific report generation could match the report quality of the proprietary models we were using, while reducing generation time and serving costs. We built AstaBrief 8B, a model that turns a research question and retrieved literature excerpts into a cited report. Asta's report generation is the first production use of AstaBrief, giving researchers an open-weights Fast mode alongside the existing Thinking mode.
