Ai2 open-sources AstaBrief 8B for faster cited scientific reports
What changed
Ai2 open-sourced AstaBrief 8B and its training data, while deploying the model as Fast mode in Asta's Generate a report feature. Built from Qwen3-8B, it turns a research question plus retrieved literature excerpts into a cited report and can be deployed on an institution's own infrastructure. Ai2 reports 51.1 seconds per report in its full Fast pipeline versus 178.5 seconds for its Claude-powered Thinking mode, while cautioning that most evaluations were conducted in 2025 and are not a current frontier-model ranking.
