Chroma
Chroma: an open image model made from Flux.1 schnell, retrained and slimmed, with a T5 text encoder and no CLIP.
What it is
Chroma is a community model built on the Flux.1 schnell architecture (about 8.9 billion parameters after pruning) and trained on a broad dataset under an open licence. Unlike Flux dev it uses real CFG and a working negative prompt.
Files and nodes
Load Diffusion Model with the Chroma file; Load CLIP with t5xxl (type chroma), no clip_l; Load VAE with the Flux ae.safetensors; the empty latent of the official template.
Settings that work
About 1 megapixel; 26 to 40 steps; cfg about 3 to 5 with a negative prompt; euler or the template's sampler and scheduler. Prompt: natural sentences.
What fits
LoRAs made for Chroma. Flux.1 LoRAs may load but often do not behave as expected. The Flux VAE fits.
