| # Mega Merged Reasoning SFT Dataset |
|
|
| Auto-merged from **44 source datasets** → **3,681,880 rows**. |
|
|
| ## Schema |
|
|
| Every row is: |
|
|
| ```json |
| { |
| "messages": [ |
| {"role": "system", "content": "..."}, |
| {"role": "user", "content": "..."}, |
| {"role": "assistant", "content": "<think>\n...\n</think>\n\nFinal answer..."} |
| ], |
| "thinking": "extracted chain-of-thought (or null)", |
| "source": "org/dataset-name" |
| } |
| ``` |
|
|
| - **`messages`** — standard OpenAI / TRL chat format |
| - **`thinking`** — isolated CoT when available (also embedded inline in `<think>` tags) |
| - **`source`** — which original repo this row came from |
|
|
| ## Formats auto-detected |
|
|
| | # | Strategy | Description | |
| |---|----------|-------------| |
| | 1 | `messages` list | OpenAI-style `role`/`content` dicts | |
| | 2 | `conversations` list | ShareGPT-style `from`/`value` dicts | |
| | 3 | `conversation` list | Variant key name | |
| | 4 | `chat`/`turns`/`dialog` list | Other conversation keys | |
| | 5 | `messages` with `reasoning_content` | OpenMed / R1 style per-turn reasoning | |
| | 6 | `prompt` + `response` | Flat pair | |
| | 7 | `instruction` + `output` | Alpaca-style flat pair | |
| | 8 | `question` + `answer` | QA-style flat pair | |
| | 9 | `query` + `completion` | Completion-style flat pair | |
| | 10 | `problem` + `solution` | Math-style flat pair | |
| | 11 | `input` + `output` | Generic flat pair | |
| | 12 | Any flat pair + `thinking`/`cot`/`reasoning` | Separate CoT column | |
| | 13 | `complex_cot` + `response` | Medical-o1 style | |
| | 14 | Nested `provenance.prompt` | Crownelius coding datasets | |
| | 15 | `system` / `system_prompt` field | System message extraction | |
| | 16 | ChatML raw text | `<|im_start|>` parsing | |
| | 17 | Alpaca raw text | `### Instruction:` parsing | |
| | 18 | Inline `<think>...</think>` | Extracted + preserved | |
| | 19 | JSON-string conversation | Stringified list parsing | |
| | 20 | Single `text` blob | Last-resort extraction | |
| | 21 | Brute-force string scan | Two longest strings → user/assistant | |
| | 22 | Prompt-only (no response) | Kept as user-only row | |
