FP8 Optimization for LingBot-Video 1.3B
ALX-OPEN-SOURCE · reddit · 2026-07-11
The author created a selective FP8 version of LingBot-Video 1.3B for ComfyUI: keeping quality-sensitive layers in BF16 and only converting parts that genuinely benefit from FP8.
On an RTX 5080, sampling time dropped from roughly 4.651s to 3.651s, showing a decent speedup. The author notes that the current workflows and nodes are still quite experimental, and Comfy will likely offer more official support later. His repository also contains some experimental workflows, like first-frame/last-frame video generation, though stability is currently average.
