svd-safety-l3_swift_jbbsft10_remove50
A Llama-3-8B-Instruct checkpoint compressed with Swift-SVD (dynamic rank allocation, alpha 0.6, 256 x 2048 WikiText2 calibration) to 50.0% of dense parameters, then recovered with SVD-LLM's stage-2 LoRA (sequential U then V, alpaca_cleaned_jbbsft_x10_l3.json, r=8, alpha=16, 2 epochs per half, lr 0.0001, batch 64, cutoff 256).
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.
