| # thoughtbase-v2 |
|
|
| Text and image prompts, each with one or more reasoning traces and a final response, collected from |
| existing open datasets. Nothing here was generated for this release; rows were filtered, deduplicated |
| and regrouped. Built for non-commercial research. |
|
|
| | | count | |
| |---|---| |
| | prompts (train / validation) | 2,740,885 / 27,510 | |
| | reasoning traces (all responses) | 4,722,758 | |
| | image traces | 934,278 (19.8%) | |
| | image files | 45 tar shards under `images/` | |
|
|
| ## Format |
|
|
| `train.jsonl` and `validation.jsonl`, one prompt per line: |
|
|
| ```json |
| {"id": "v3_gqa_1:…", "prompt": "What is the color of that vase?…", |
| "image_paths": ["images/ab/ab12….jpg"], |
| "responses": [{"cot": "The user wants…", "final_answer": "Green", "model": "v3_gqa_1"}], |
| "split_group": "image:ab12…", "source": {"dataset": "nvidia/Nemotron-Image-Training-v3", "source": "v3_gqa_1", "row": 17}} |
| ``` |
|
|
| - `responses` holds every distinct trace for the same prompt and images (e.g. several solutions of one |
| math problem). `model` names the source the trace came from. |
| - Multi-turn source rows become one prompt per turn: earlier turns keep their question and final |
| answer, only the target turn has reasoning. |
| - Grounding answers use `<box>[[x1, y1, x2, y2], …]</box>` with coordinates on a 0–1000 grid. |
| - About 1% of prompts are in validation, split by image hash or whitespace-normalized prompt, so no |
| image or prompt appears in both splits. |
| - Length limits (Qwen3.5 tokenizer, real token counts): prompt + 256 tokens per image ≤ 4096, |
| cot < 16384, final answer < 4096. Longer items were dropped, not truncated. |
|
|
| ## Use |
|
|
| ```bash |
| hf download JonesLin/thoughtbase-v2 --repo-type dataset --local-dir thoughtbase-v2 |
| cd thoughtbase-v2 && for t in images/*.tar; do tar -xf "$t"; done # creates images/<sha[:2]>/<sha>.<ext> |
| ``` |
|
|
| Image paths in the JSONL are relative to the folder holding it. |
|
