The DeepResearch-9K lacks tool responses.

[ChaSe-Michaelmas]

After downloading the data from Hugging Face, I noticed that the search_trajectory field only contains two roles, User and Assistant, and whenever the Assistant calls a tool, the User role is repeated instead of a tool response. May I ask why this is the case?

Hello! The search_trajectory field is designed to preserve the original conversation flow between the User and the Assistant. In our data format, tool calls and their results are not represented as separate tool or function roles. Instead, we keep the structure simple:

role: "user" is used for both the initial user question and the simulated tool responses (to maintain the sequential context).

role: "assistant" contains the model’s reasoning (in ) and tool calls (in <tool_call>).

We believe this design can simplify the format of long Deep Research conversations and effectively reflect the corresponding observations.
