A synthetic fine-tuning dataset created from Claude 4.6/4.7. 8,706 total examples all with reasoning. I haven't reviewed the data but there was some basic cleaning applied. Refusals and safety should be repressed. I ended up with extra usage on a plan before it expired.

| Split | File | Examples | Contents |
|-------|------|---------:|----------|
| **Full** | `full_train.jsonl` | 8,706 | All examples across all 28 categories. |
| **Instruct** | `instruct_train.jsonl` | 7,217 | All 24 instructional categories — coding, math, sciences, humanities, arts, finance, medicine, law, business, linguistics, creative writing, general. |
| **Roleplay** | `roleplay_train.jsonl` | 1,489 | The four creative categories — `roleplay_hero`, `roleplay_villain`, `roleplay_crossover`, `narrative_prose`. |
| **Code** | `code_train.jsonl` | 1,840 | `coding` + `math` only. For coding/math-focused fine-tunes. |
