# Model Card

**Mistral 7B v0.1 CT-Choice** is a fine-tuned [Mistral 7B v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1) model that provides well-calibrated confidence estimates for multiple-choice question answering.

The model is fine-tuned (calibration-tuned) using a [dataset](https://huggingface.co/datasets/calibration-tuning/Mistral-7B-v0.1-20k-choice) of *multiple-choice* generations from `mistralai/Mistral-7B-v0.1`, labeled for correctness. 
At test/inference time, the probability of correctness defines the confidence of the model in its answer. 
For full details, please see our [paper](https://arxiv.org/abs/2406.08391) and supporting [code](https://github.com/activatedgeek/calibration-tuning).

**Other Models**: We also release a broader collection of [Multiple-Choice CT Models](https://huggingface.co/collections/calibration-tuning/multiple-choice-ct-models-66043dedebf973d639090821).

## Usage

This adapter model is meant to be used on top of `mistralai/Mistral-7B-v0.1` model generations.

The confidence estimation pipeline follows these steps,
1. Load base model and PEFT adapter.
2. Disable adapter and generate answer.
3. Enable adapter and generate confidence.

All standard guidelines for the base model's generation apply.

For a complete example, see [play.py](https://github.com/activatedgeek/calibration-tuning/blob/main/experiments/play.py) at the supporting code repository.

**NOTE**: Using the adapter for generations may hurt downstream task accuracy and confidence estimates. We recommend using the adapter to estimate *only* confidence.
