Whittle 14.7B logit-distillation adapter (research preview)
LoRA r32 trained to match the output distribution of the Qwen3.8-27B parent, not
just the reference answers. Targets are the parent's top-128 log-probs per token
(recorded once over the heal corpus), and the loss is KL against those plus a small
cross-entropy anchor, taken on assistant turns only.
Why distribution rather than labels: the base model already predicts this corpus almost
perfectly (cross-entropy ~4e-05) while its distribution sits ~2.5 nats from the parent's.
Hard labels had nothing left to teach; the distribution did.
3.90M tokens, ~1.2 epochs, 80 minutes on one A100. The teacher pass ran the parent at
nf4, so the deep tail of the targets is approximate.
Research preview, needs further work. Published as a record of method and
measurements. See the Whittle collection for the models themselves.
