Prompt size limits¶
Limits are enforced per model × detail combination. See also Supported models in the main README.
Limits are enforced per model × detail combination. All models have Concise / Balanced / Rich presets; long-form models also enforce minChars:
| Detail | Qwen-Image-Edit | Edit-2511 | Image-2512 | Image-2.0 | FLUX.2 Klein | SDXL | SD1.5 |
|---|---|---|---|---|---|---|---|
| Concise | ~280 chars | ~220 chars | ~320 chars | ~400 chars | ~250 chars | ~280 chars | ~220 chars |
| Balanced | ~520 chars | ~420 chars | ~380–650 chars | ~550–800 chars | ~450–700 chars | ~520 chars | ~380 chars |
| Rich | ~920 chars | ~680 chars | 700–1000 chars | 1100–1400 chars | 900–1200 chars | ~780 chars | ~520 chars |
Other families use limits tuned to their encoder (see src/lib/comfy-models/limits.ts).
