LlamaGen-FlashAR

This repository collects FlashAR checkpoints for LlamaGen variants.

FlashAR is introduced in "FlashAR: Efficient Post-Training Acceleration for Autoregressive Image Generation". It accelerates raster-scan autoregressive image generation with a vertical prediction branch and a learnable fusion gate, enabling anti-diagonal decoding.
