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.

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.

What is Chroma?
Chroma is a highly specialized Image generation AI Model of type Safetensors / Checkpoint AI Model created by AI community user Lodestone. Derived from the powerful Stable Diffusion (Other) model, Chroma has undergone an extensive fine-tuning process, leveraging the power of a dataset consisting of images generated by other AI models or user-contributed data. This fine-tuning process ensures that Chroma is capable of generating images that are highly relevant to the specific use-cases it was designed for, such as base model, chroma, base_model.
With a rating of 0 and over 0 ratings, Chroma is a popular choice among users for generating high-quality images from text prompts.
Can I download Chroma?
Yes! You can download the latest version of Chroma from here.
How to use Chroma?
To use Chroma, download the model checkpoint file and set up an UI for running Stable Diffusion models (for example, AUTOMATIC1111). Then, provide the model with a detailed text prompt to generate an image. Experiment with different prompts and settings to achieve the desired results. If this sounds a bit complicated, check out our initial guide to Stable Diffusion – it might be of help. And if you really want to dive deep into AI image generation and understand how set up AUTOMATIC1111 to use Safetensors / Checkpoint AI Models like Chroma, check out our crash course in AI image generation.
