Speed Any mode 8 steps
PDD official acceleration, 8-step (dedicated node required)
Alibaba PAI's Parallel Decoding Distillation with a head bank; plain LoRA loaders silently drop it; live arena rank on its LoRA page.
How to run it
- 1 Install the PDD node pack (it reads the official files directly)
- 2 Use the sampler and sigmas from the node docs, CFG=1.0
- 3 Do not stack with any other distill LoRA or step cache
Official distill with low quality cost, but the most node-bound recipe — only use sigmas from the PDD node.
