Qwen Image 2.1's built-in prompt enhancer is unusable: 12k tokens still not enough
dtdisapointingresult · reddit · 2026-10-19
A user reports Qwen Image 2.1's default workflow prompt enhancer is effectively broken: at the default 4096 maxtokens generations fail with empty prompts, and even 12k tokens isn't enough — with thinking on, tokens run out during reasoning producing no output; with thinking off, the overlong instruction gets truncated and degrades the image. The author argues Qwen models overthink and are poor local PE models, noting r/LocalLLaMA users switching to SwiftQwen 27B, a finetune that halves reasoning length. Recommendation: keep the enhancer off.
