## Dataset Summary

QuixiMath-1B is a synthetic math reasoning corpus generated from the QuixiMath
procedural problem generators. Each record contains a natural-language problem,
explicit step-by-step scratchpad opcodes, a canonical final answer, and metadata
for filtering or reweighting by skill, operation, grade band, and relative
difficulty.

The canonical corpus is coverage-first rather than prescriptively stratified:
trainers can choose their own sampling mix using the included metadata columns.
The size configs are nested prefix subsets within each split.

## How to Load

```python
from datasets import load_dataset

ds = load_dataset("QuixiAI/QuixiMath-1B", "100M_tokens")
train = load_dataset("QuixiAI/QuixiMath-1B", "100M_tokens", split="train")
```

## Configs And Splits

| Config | Split | Rows | Estimated tokens |
|---|---|---:|---:|
| `preview` | `train` | 50,000 | 6,134,016 |
| `10M_tokens` | `train` | 100,000 | 12,308,849 |
| `10M_tokens` | `validation` | 10,000 | 1,244,720 |
| `100M_tokens` | `train` | 800,000 | 98,641,588 |
| `100M_tokens` | `validation` | 50,000 | 6,164,238 |
| `100M_tokens` | `test` | 50,000 | 6,077,648 |
| `1B_tokens` | `train` | 8,800,000 | 1,104,706,100 |
| `1B_tokens` | `validation` | 100,000 | 12,333,425 |
| `1B_tokens` | `test` | 100,000 | 12,176,460 |

The largest config contains 9,000,000 rows and approximately
1,129,215,985 rough text tokens, estimated as `len(text) / 4`.

## Data Schema

Columns:

- `row_id`: stable integer row index within the split.
- `example_id`: stable string ID such as `train-000000123`.
- `problem_id`: generator-provided problem identifier.
- `generator`: generator class name.
- `generator_label`: generator class plus variant marker when applicable.
- `operation`: problem operation/category label.
- `grade_level`: one of `elementary`, `middle`, `high`, `college`, `graduate`.
- `difficulty`: integer 1-5, relative to `grade_level`.
- `problem`: problem text.
- `steps`: list of pipe-delimited scratchpad steps.
- `final_answer`: canonical answer string.
- `text`: training-ready text field containing problem, steps, and final answer.

## Generation

Generated at: `2026-07-07T00:44:54.279574+00:00`

Source repository: `/home/hotaisle/datasets/QuixiMath`

Source git commit: `5283d55a85d7a127c8cfa5a1b5baf6b96dbc3301`

Source git dirty: `True`

Exact duplicate `(operation, problem)` pairs were skipped across the generated
largest splits before nested configs were materialized. Per-generator duplicate
and error counts are stored in `generation_stats.json`.
