svd-safety-l3_remove20_swapgapiter_b010

A Llama-3-8B-Instruct checkpoint compressed with SVD-LLM to 80.0% of dense parameters, then edited by 10 of 10 rounds of iterative parameter-neutral swap selected by the gap_iter rule (up to 0.1% of dense parameters per round; the full run's budget is 1.0%).

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.

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-3-8B-Instruct: 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.
