I guess it might not be the best to only remove the mentions of guidance distillation, right? The reason why I did not open the PR myself was because I am unsure what to replace the description with. Maybe copying the description from the SDXL pipeline guidance_scale parameter might be more appropriate?

I am also wondering if it will be good to add further clarification about Chroma being dedistilled to use true CFG, but I guess that will make the docs too verbose?

[SahilCarterr]

@mingyi456 . Now docs are consistent . Mentioning true_cfg will break the consistency among pipelines

[stevhliu]

Thanks for clarifying!

I think this should be 5.0 (same for the im2img pipeline)?

diffusers/src/diffusers/pipelines/chroma/pipeline_chroma.py

Line 649 in 5796735

guidance_scale: float = 5.0,

[mingyi456]

Actually, where is the source that says chroma's default cfg should be 5.0? The comfyui recommended workflow seems to say it should be 4.0, meanwhile I had always thought that 3.5 was the correct default value.

Pinging @Ednaordinary who would know better since they implemented the pipeline :)

[Ednaordinary]

both lodestones/Chroma1-Base and lodestones/Chroma1-HD have 3.0 in their readme example, though anywhere between 3 and 4 should be fine! thanks for the ping

[SahilCarterr]

Then cfg 3.5 is fine . Thanks @Ednaordinary and @mingyi456
