- 7Hugging Face Blog·8/10/2026researchHugging Face shows cheaper large-scale knowledge distillation for LLMs
The article presents a method for making knowledge distillation for large language models much cheaper by caching the teacher model’s top-K logits offline and using a fused chunked KL loss. The approach reduces VRAM usage enough to make distillation experiments feasible on a single GPU in some cases, instead of requiring large multi-GPU setups.
