| # Math Reasoning, sample dataset |
|
|
| A small, illustrative sample for fine-tuning a model to **solve math problems step by |
| step and give a checkable final answer**. It accompanies the cookbook |
| [Fine-tune gpt-oss for math reasoning with Halo](https://github.com/whitecircle/halo). |
|
|
| This is a **format-illustration sample (48 rows)**, not a production training set. It |
| shows the exact record shape the recipe expects; swap in a larger corpus at scale. |
|
|
| ## Configs |
|
|
| | Config | File | Schema | Used by | |
| |---|---|---|---| |
| | `sft` (default) | `sft.jsonl` | `{"prompt": [system, user, assistant]}` | supervised fine-tuning | |
| | `labeled` | `labeled.jsonl` | `{"question": str, "answer": str}` | online-GRPO verifiable reward | |
|
|
| The `sft` split teaches the format, reason through the problem then state the final |
| answer wrapped in `\boxed{...}` so it can be parsed with one regex. The `labeled` split |
| carries the same problems with only the gold answer, for the reinforcement-learning stage |
| that rewards correct answers directly. |
|
|
| ## Record example (`sft`) |
|
|
| ```json |
| { |
| "prompt": [ |
| {"role": "system", "content": "You are a math tutor. Solve the problem step by step, then give the final answer on the last line as \\boxed{...}."}, |
| {"role": "user", "content": "A right triangle has legs 6 and 8. Find the hypotenuse."}, |
| {"role": "assistant", "content": "By the Pythagorean theorem, h = sqrt(6^2 + 8^2) = sqrt(100) = 10.\n\nThe answer is \\boxed{10}."} |
| ] |
| } |
| ``` |
|
|
| ## Composition |
|
|
| 48 problems spanning arithmetic, fractions and percentages, linear and quadratic |
| equations, geometry, number theory, combinatorics and probability, sequences, and word |
| problems (rates, mixtures, work, compound interest). Answers are integers, simple |
| fractions, or a small radical, chosen so an exact-match grader can score them cleanly. |
|
|
| ## Intended use |
|
|
| Supervised fine-tuning and RLVR for step-by-step math reasoning, as in the linked |
| cookbook. For a real run, scale to a few thousand problems with worked solutions and |
| raise the completion budget so the model has room to reason. |
