+# Reproduction guide
+This directory contains the necessary information and assets to reproduce the results obtained during this Heretic run.
+## Models
+- **Base model:** [Qwen/Qwen2.5-Coder-0.5B-Instruct](https://huggingface.co/Qwen/Qwen2.5-Coder-0.5B-Instruct) (Commit: [`ea3f247`](https://huggingface.co/Qwen/Qwen2.5-Coder-0.5B-Instruct/commit/ea3f2471cf1b1f0db85067f1ef93848e38e88c25))
+## Datasets
+- [mlabonne/harmful_behaviors](https://huggingface.co/datasets/mlabonne/harmful_behaviors) (Commit: [`01cead0`](https://huggingface.co/datasets/mlabonne/harmful_behaviors/commit/01cead01398926d81f7c52bdb790ee8cf77ebba7))
+- [mlabonne/harmless_alpaca](https://huggingface.co/datasets/mlabonne/harmless_alpaca) (Commit: [`02c6a92`](https://huggingface.co/datasets/mlabonne/harmless_alpaca/commit/02c6a92cfcf11bb0c387334f8146d149d65b587f))
+## Selected trial
+- **Trial number:** 21
+- **Refusals:** 7/100 (baseline: 51/100)
+- **KL divergence:** 0.0289 (baseline: 0 *(by definition)*)
+## Environment
+- **Heretic:** v2.0.0 (Origin: PyPI)
+- **PyTorch:** 2.11.0+cu128
+- **Other dependencies:** See [`requirements.txt`](requirements.txt).
+## Contents of this directory
+- [`requirements.txt`](requirements.txt): The exact versions of all Python packages.
+- [`config.toml`](config.toml): The exact configuration used, including the RNG seed.
+- [`Qwen--Qwen2--5-Coder-0--5B-Instruct.jsonl`](Qwen--Qwen2--5-Coder-0--5B-Instruct.jsonl): The Optuna study journal containing the history of all trials.
+- [`SHA256SUMS.txt`](SHA256SUMS.txt): Cryptographic hashes for all weight files.
+- [`reproduce.json`](reproduce.json): A machine-readable file containing all reproducibility information.
+## How to reproduce
+> [!TIP]
+> You can automate this process, including all verification steps, by downloading the `reproduce.json` file and running
+> `heretic --reproduce reproduce.json`.
+1. Install the exact version of Heretic indicated in the **Environment** section above, from its original source.
+1. Install the packages listed in `requirements.txt`: `pip install -r requirements.txt`
+1. Install the correct version of PyTorch: `pip install torch==2.11.0+cu128 --index-url https://download.pytorch.org/whl/cu128`
+1. Place the provided `config.toml` in your working directory.
+1. Run Heretic without any additional arguments: `heretic`
+1. Wait for the run to finish, then select trial **21** and export the model.
+1. Verify that the weight files have been exactly reproduced by comparing their SHA-256 hashes against those in `SHA256SUMS.txt`:
+   `sha256sum -c SHA256SUMS.txt` (or look at the hashes online if you uploaded to Hugging Face)
+> [!TIP]
+> To use the included Optuna study journal `Qwen--Qwen2--5-Coder-0--5B-Instruct.jsonl`, place it in the checkpoints directory (usually `checkpoints/`) before running Heretic.
+>
+> This allows you to export other models from the Pareto front, or to run additional trials without having to re-run the stored trials.
