# F* Proof Completion Dataset (Chat Format)

This dataset is a preprocessed version of [`microsoft/FStarDataSet-V2`](https://huggingface.co/datasets/microsoft/FStarDataSet-V2). It has been reformatted into a chat-style JSONL structure for supervised fine-tuning of language models on F* function synthesis and proof completion.

## Dataset Structure

The dataset consists of three splits:

* `fstar_train.jsonl`
* `fstar_validation.jsonl`
* `fstar_test.jsonl`

Each line in these files is a JSON object with the following schema (where the keys correspond to the keys in the original dataset):

```json
{
  "messages": [
    {"role": "user", "content": "Complete this F* function with a correct proof.\nType: <verbose_type>\nEffect: <effect>\nContext: <file_context>\nPartial implementation: <partial_definition>"},
    {"role": "assistant", "content": "<completed_definiton>"}
  ]
}
```

This format is compatible with supervised fine-tuning frameworks such as TRL, Fireworks AI SFT, or OpenAI-style chat tuning.

* **Modifications:** Reformatted to chat-based JSONL files. No additional data or content changes were made.

## Intended Use

The dataset is intended for research and experimentation in program synthesis, theorem proving, and fine-tuning large language models on functional proof-oriented languages such as F*.
