Chroma 发布 Context-1:20B 参数自编辑搜索智能体
Chroma 训练并开源了 Context-1,一个 20B 参数的智能体搜索模型,在八千多个合成任务上训练,检索表现接近前沿大模型,成本更低、推理速度最高提升 10 倍。它作为检索子智能体工作,把高层查询拆成子查询并多轮搜索,在上下文窗口填满时主动丢弃无关结果,并以 Apache 2.0 许可开放权重和完整数据生成流程。训练采用先召回后精确的分阶段课程,配合基于抽取验证的合成任务生成流程,与人工判断的一致率超过 80%。

rom extraction, we retrieve the full text of referenced prior art patents. For domestic patents after 2001, we pull directly from USPTO. For older or international patents, we use Google Patents via SearchAPI. We extract the abstract, description, and claims from each referenced patent. For distractors, we collect patents returned as “similar” in the Google Patents search results, which share topical overlap but were not actually cited as prior art.
