Qwen3 Embedding 0.6B LRAT Full-v1 to Broad Extrapolation a1.25
This checkpoint extends the aggregate training direction from the team's
full-v1 retriever to broad-g16-v2:
full-v1 + 1.25 * (broad-g16-v2 - full-v1)
Both endpoints start from Qwen/Qwen3-Embedding-0.6B and were trained only on
the organizer-provided LRAT trajectories and corpus. This is a global parameter
direction; no A-board query, qrel, per-query failure, or external corpus was
used to construct it. No weights from another pretrained checkpoint are used.
The checkpoint was selected by aggregate fixed-seed evaluation with the released BrowseComp-Plus Agent and Judge workflow using Qwen3.5-4B. Local scores are used only for checkpoint selection and are not claimed as official results.
