Ai2 open-sources 8B scientific report generation model AstaBrief
Ai2 has open-sourced AstaBrief, an 8B parameter scientific report generation model built on Qwen3-8B, which converts research questions and retrieved literature excerpts into cited reports. It is now available in Asta's Generate a report feature as Fast mode, alongside the Claude-powered Thinking mode, and reduces average report generation time from 178.5 seconds to 51.1 seconds, about 3.5 times faster. The model weights and training data are released, with the pipeline using real research queries, citation-focused filtering, and preference data.
- for who

score
score 8 out of 10. 0-10: how dense the facts are, multiplied by how much you can do with them after reading. 8+ means the topic's evidence bar is met: benchmarks and availability for a new model, amount and investors for a funding round, revenue figures for a solo-money story. Below 5 an item does not enter the digest. A press release scores 3 or less, a reprint loses 2, anything older than 14 days loses 1, a headline that misleads loses 3.
