Hey everyone!

Chroma is a 8.9B parameter model based on FLUX.1-schnell (technical report coming soon!). It’s fully Apache 2.0 licensed, ensuring that anyone can use, modify, and build on top of it—no corporate gatekeeping.

The model is still training right now, and I’d love to hear your thoughts! Your input and feedback are really appreciated.

What Chroma Aims to Do

• Training on a 5M dataset, curated from 20M samples including anime, furry, artistic stuff, and photos.

• Fully uncensored, reintroducing missing anatomical concepts.

• Built as a reliable open-source option for those who need it.

• Live AIM Training Logs: https://training.lodestone-rock.com/

• ComfyUI Inference node [WIP]: https://github.com/lodestone-rock/flux-mod

• ComfyUI workflow: https://huggingface.co/lodestones/Chroma/resolve/main/simple_workflow.json

• Training code!: https://github.com/lodestone-rock/flow

Quantization options

• Alternative option: FP8 Scaled Quant (Format used by ComfyUI with possible inference speed increase)

• Alternative option: GGUF Quantized (You will need to install ComfyUI-GGUF custom node)

Special Thanks

Shoutout to Fictional.ai for the awesome support — seriously appreciate you helping push open-source AI forward.

Support Open-Source AI

The current pretraining run has already used 5000+ H100 hours, and keeping this going long-term is expensive.

If you believe in accessible, community-driven AI, any support would be greatly appreciated.
