Spec-o3-ColdStartSFT
Spec-o3 Cold-Start (iMCoT) Dataset
Project Page | Paper | Code
Dataset Summary
This dataset contains expert-approved spectral inspection trajectories for cold-start supervised fine-tuning (SFT) of Spec-o3, a tool-augmented vision-language agent for astronomer-aligned spectral inspection and candidate vetting.
Each sample is an interleaved multimodal chain-of-thought (iMCoT) trajectory that alternates between:
Textual inspection reasoning, and
Structured tool calls that… See the full description on the dataset page: https://huggingface.co/datasets/Maxwell-Jia/Spec-o3-ColdStartSFT.SciLM-CoT_ColdStart

PhysR1Corp Cold-Start — Tool-Using Physics Trajectories (Text + Multimodal)
SFT cold-start dataset for Physics-R2 / Phase E (a tool-use RL paper for VLMs, target ICLR 2027).
1,973 audited trajectories — 1,740 text-only + 233 multimodal — covering the full PhysR1Corp
corpus (all 2,268 problems). Each trajectory solves a physics problem using a custom SymPy tool
routed through the project's harness.sandbox runtime. The trajectory schema matches the W6
RL-training inference format… See the full description on the dataset page: https://huggingface.co/datasets/shanyangmie/physr1corp-cold-start.R3-RAG-ColdStartTrainingDataLeanabell-Prover-V2-Coldstart-DSBesiegeField_humandataset_coldstart
