LiteResearcher — SFT Cold-Start Data Distilled deep-research trajectories used for the SFT cold-start of LiteResearcher-4B This dataset contains the 68,231 multi-turn deep-research trajectories used to train the SFT cold-start checkpoint that RL (GRPO+TIS) is later launched from — the "68.2 K distilled deep-research trajectories" referenced in the paper and in LiteResearcher-Data.
