Heretic implements a parametrized variant of directional ablation. For each

MLP down-projection), it identifies the associated matrices in each transformer

layer, and orthogonalizes them with respect to the relevant "refusal direction",

layer, and orthogonalizes them with respect to the relevant "residual direction",

inhibiting the expression of that direction in the result of multiplications

Refusal directions are computed for each layer as a difference-of-means between

Residual directions are computed for each layer as a difference-of-means between

the first-token residuals for "harmful" and "harmless" example prompts.

## 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`.
|
||||
|
||||
{system_instructions}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: `{pytorch_install_command}`
|
||||
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 **{trial.user_attrs["index"]}** and export the model.
|
||||
1. Verify that the weight files have been exactly reproduced by comparing their SHA-256 hashes against those in `SHA256SUMS`:
|
||||
`sha256sum -c SHA256SUMS` (or look at the hashes online if you uploaded to Hugging Face)
|
||||
|
||||
> [!TIP]
|
||||
> To use the included Optuna study journal `{checkpoint_filename}`, 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.

# Test Suite Guide
|
||||
|
||||
Whenever we change any code-logic related to `src/heretic/model.py` or `config.toml` *(e.g. `row_normalization`, `full_normalization_lora_rank`, `winsorization_quantile`, etc)* which can affect a model's reproduciblity; Use these tests which are designed to verify that those changes does not affect reproducibility, unless they are meant to (like when we'll integrate ARA branch in future).
|
||||
|
||||
## How to test
|
||||
|
||||
1. Choose any model from [tiny-random](https://huggingface.co/tiny-random) org which provides tiny models useful for debugging.
|
||||
|
||||
**Example**: [tiny-random/minicpm5](https://huggingface.co/tiny-random/minicpm5).
|
||||
|
||||
> [!NOTE]
|
||||
> It is highly recommended to use a model which does not have a `special_tokens_map.json` file in the repo.
|
||||
> Because those files are almost always wrong in `tiny-random/*` models compared to the original model.
|
||||
|
||||
2. Clone that model repository using Git and generate the SHA256 hashes using `sha256sum`:
|
||||
|
||||
**On Linux**:
|
||||
|
||||
```bash
|
||||
sha256sum -b * > ../SHA256SUMS.LABEL
|
||||
```
|
||||
|
||||
**On Windows**:
|
||||
|
||||
```bash
|
||||
sha256sum * | Out-File -Encoding utf8NoBOM ../SHA256SUMS.LABEL
|
||||
```
|
||||
|
||||
> [!TIP]
|
||||
> On windows, `sha256sum` is generally pre-installed by *Git for windows*.
|
||||
|
||||
**Verify with**:
|
||||
|
||||
```bash
|
||||
Get-Command sha256sum`
|
||||
```
|
||||
|
||||
**Expected**:
|
||||
|
||||
```bash
|
||||
CommandType Name Version Source
|
||||
----------- ---- ------- ------
|
||||
Application sha256sum.exe 0.0.0.0 C:\Program Files\Git\usr\bin\sha256sum...
|
||||
```
|
||||
|
||||
> [!NOTE]
|
||||
> You must use Windows Powershell `v7.X` not the core which is `v5.1`. This is required for `-Encoding utf8NoBOM` to work.
|
||||
>
|
||||
> See [Differences between Windows PowerShell 5.1 and PowerShell 7.x](https://learn.microsoft.com/en-us/powershell/scripting/whats-new/differences-from-windows-powershell?view=powershell-7.6) documentation.
|
||||
|
||||
Where `LABEL` describes the type of system you are running the tests on.
|
||||
|
||||
**Example**:
|
||||
|
||||
- `SHA256SUMS.windows` (For windows)
|
||||
- `SHA256SUMS.ci` (For GitHub CI)
|
||||
- `SHA256SUMS.linux` (For linux)
|
||||
|
||||
3. Run the tests with:
|
||||
|
||||
```bash
|
||||
uv run run_tests.py
|
||||
```
|
||||
|
||||
The output hashes *should FAIL* against the `Valid hashes` in `SHA256SUMS` file of the test model you added. This is expected since Heretic changes the model. Without **Step 2**, the test model's folder will simply be ignored because it will not have a hash SUMS file to compare against.
|
||||
|
||||
4. After that go to the output `TEST_MODEL_DIR/model` folder and re-generate the Actual hashes based on the system you are using.
|
||||
|
||||
```bash
|
||||
cd TEST_MODEL_DIR/model
|
||||
sha256sum -b * > ../SHA256SUMS.LABEL # or use windows command.
|
||||
```
|
||||
|
||||
5. Re-run the tests with:
|
||||
|
||||
```bash
|
||||
uv run run_tests.py
|
||||
```
|
||||
|
||||
This time the tests *should PASS* because we added the new hashes which are expected to be reproduced on the same system.
|
||||
|
||||
6. After that push the `SHA256SUMS.LABEL` files and wait for GitHub CI actions to run those tests.
|
||||
|
||||
Since PyTorch does not guarantee exact cross-system reproducibility regardless of configuration, multiple valid hashes can be provided for each output file. The above update must be performed for each `TEST_MODEL_DIR` and on each type of system.
|
||||
|
||||
For this, copy the `Actual hash` value for *each mismatched unidentical* file into a `SHA256SUMS.ci` file.
|
||||
|
||||
7. After that push the `SHA256SUMS.ci` files and wait for GitHub CI actions to re-run those tests.
|
||||
|
||||
This time the tests *should* PASS because we added the new hashes which are expected to be reproduced on CI.
