做深度研究或复杂推理系统的开发者，VeriTrace 用显式反馈替代隐式推理，解决了信息污染和错误传播的痛点，值得在开源项目中尝试。
深度研究智能体在处理复杂信息时，现有系统依赖大模型隐式推理来演化中间表征，导致信息污染和错误传播。VeriTrace 提出通过显式反馈循环（解释更新、偏差反馈、模式修正）来持续对齐任务理解与现实，并基于认知图谱框架实现。在 Qwen3.5-27B 基座上，VeriTrace 在 DeepResearch Bench 洞察力指标上提升 4.22 个百分点，在 DeepConsult 上胜率提升 5.9 个百分点。与 Config-DeepSeek 结合，它取得了 DRB 上最强的可复现开源结果。
VeriTrace: Evolving Mental Models for Deep Research Agents
Deep research agents face vast, interdependent, and pervasively uncertain information. Existing systems explore what evolving intermediate representations should look like, but leave their evolution to the LLM's implicit reasoning. Without explicit regulation, the intermediate layer is easily contaminated by mixed-quality information and propagates errors along its dependencies, so model scale often ends up substituting for absent regulation. We argue that an agent's mental model should instead evolve through explicit feedback that continuously aligns task understanding with reality, and identify three regulatory loops: interpretive update, deviation feedback, and schema revision. We realise this in VeriTrace, a cognitive-graph framework that explicitly implements the three loops. Using matched Qwen3.5-27B backbones, VeriTrace improves over the strongest matched baseline by 4.22 pp on DeepResearch Bench (DRB) Insight (1.49 pp Overall) and by 5.9 pp Overall win rate on DeepConsult. With Config-DeepSeek, it achieves the strongest reproducible open-source result on DRB.
