Spectrum gives Qwen2.1 over 2x speedup on an RTX 3060 12GB after a one-shot vibe-code

A user shares Spectrum, a speedup for Qwen2.1 built in a single vibe-coded shot, delivering over 2x faster generation on an RTX 3060 12GB. They ran one timing comparison against Easy Cache and the base pipeline, and found the two can be combined (faster still) though they recommend picking one.

Image quality: composition stays close to base generations but with a softer, airbrushed feel — which the author attributes partly to the base model itself. I2I editing worked fine up to base + 1 reference image. Self-described "vibe coded slop," best suited for fast prompt iteration.
