Ai2 开源科学报告生成模型 AstaBrief 8B

AI 摘要

Ai2 开源了 AstaBrief 8B，一个专为科学报告生成训练的小型开放权重模型，可将研究问题与检索到的文献片段转化为带引用的报告。该模型基于 Qwen3-8B，采用 SFT 和 DPO 训练，已作为 Asta 平台的 Fast 模式上线，并同时开源模型权重和训练数据。相比 Claude 驱动的 Thinking 模式，Fast 模式平均每份报告生成时间从 178.5 秒降至 51.1 秒，约快 3.5 倍，且质量相当。

Language models can already help researchers search the literature, synthesize evidence, and work through complex questions. But scientific work places particular demands on these models—answers need to stay grounded in evidence, the models need to preserve what the evidence actually supports rather than quietly broadening a study’s conclusions, and researchers need to be able to verify the final outputs. We see that in how scientists use Asta, our agentic platform for scientific work. Instead o
