"description": "DEFRAGGED derivative of [`qwen3.5-4b-code-forged`](https://huggingface.co/continuum-ai/qwen3.5-4b-code-forged). Same forge journey as the parent (prune + train as published in the parent's alloy); this artifact adds a single 'defragged' transformation stage to produce a smaller / faster / more-portable variant of the same logical model. Inherits the parent's published benchmark results; per-variant evaluation samples will land in a follow-up release if/when per-variant benchmarks are run.",

The parent's prune stage marks heads as dead via forward-hooks; this artifact reifies that pruning by physically reshaping the projection matrices to remove the dead heads' parameters. Behaviorally equivalent to the parent (same logits per surviving head); structurally smaller on disk and in VRAM."
