# svd-safety-llama2_7b_chat_remove_30_seed42

A Llama-2-7b-chat checkpoint compressed with SVD-LLM to **70.0% of dense
parameters**, then given a **0.0% parameter budget** of restored SVD
components selected by the **`unknown`** rule.

This is a research artifact from a study of how SVD compression damages safety
behaviour and which component-selection rule best repairs it. It is one cell of a
grid over selection rules and budgets; it is **not** a general-purpose chat model.

## Provenance

| field | value |
|---|---|
| base (uncompressed) | `meta-llama/Llama-2-7b-chat-hf` |
| compression | SVD-LLM, 30.00% of parameters removed |
| selection rule | `unknown` |
| restore budget | 0.000% of dense parameters |
| components restored | 0 |
| components swapped out | 0 |
| resulting parameter fraction | 0.6998 |
| seed | 42 |

## Measured

| metric | value |
|---|---|
| AdvBench ASR (HarmBench judge) | 0.0462 |
| StrongREJECT ASR (HarmBench judge) | 0.0575 |
| Macro over-refusal (WildGuard) | 0.2795 |
| WikiText-2 perplexity | 9.7347 |


## Intended use and limitations

This checkpoint exists to measure safety/utility trade-offs under compression.
Several arms in the grid are **deliberately safety-degraded** relative to
Llama-2-7b-chat: compression alone raises attack-success rate, and the point of
the study is to quantify that and test recovery. Treat any given cell as an
experimental subject, not as a deployable assistant, and evaluate it yourself
before drawing conclusions from it.
