Ai2 Open-Sources AstaBrief 8B Weights — A Single-Pass Scientific Report Generator with Citations
The Allen Institute released the AstaBrief 8B model under the Apache 2.0 license — a fine-tune of Qwen3-8B trained via SFT and DPO on 47,000 real ScholarQA queries. It writes a scientific report with citations in a single pass: in 72% of pairwise comparisons, it outperformed the multi-step Asta pipeline on Claude, and generates a report in an average of 51 seconds versus 178.
