I got a ton of great feedback, and I'm excited to announce that the base model training is finally complete, and the whole family of models is now ready for you to use!A quick refresher on the promise here: these are true base models.I haven't done any aesthetic tuning or used post-training stuff like DPO. They are raw, powerful, and designed to be the perfect, neutral starting point for you to fine-tune. We did the heavy lifting so you don't have to.And by heavy lifting, I mean about 105,000 H100 hours of compute. All that GPU time went into packing these models with a massive data distribution, which should make fine-tuning on top of them a breeze.As promised, everything is fully Apache 2.0 licensed—no gatekeeping.TL;DR:Release branch:<ul><li><a target="_blank" rel="ugc" href="https://huggingface.co/lodestones/Chroma1-Base">Chroma1-Base</a>: This is the core 512x512 model. It's a solid, all-around foundation for pretty much any creative project. You might want to use this one if you’re planning to fine-tune it for longer and then only train high res at the end of the epochs to make it converge faster.</li><li><a target="_blank" rel="ugc" href="https://huggingface.co/lodestones/Chroma1-HD">Chroma1-HD</a>: This is the high-res fine-tune of the Chroma1-Base at a 1024x1024 resolution. If you're looking to do a quick fine-tune or LoRA for high-res, this is your starting point.</li></ul>Research Branch:<ul><li><a target="_blank" rel="ugc" href="https://huggingface.co/lodestones/Chroma1-Flash">Chroma1-Flash</a>: A fine-tuned version of the Chroma1-Base I made to find the best way to make these flow matching models faster. This is technically an experimental result to figure out how to train a fast model without utilizing any GAN-based training. The delta weights can be applied to any Chroma version to make it faster (just make sure to adjust the strength).</li><li><a target="_blank" rel="ugc" href="https://huggingface.co/lodestones/chroma-debug-development-only/tree/main/radiance">Chroma1-Radiance [WIP]</a>: A radical tuned version of the Chroma1-Base where the model is now a pixel space model which technically should not suffer from the VAE compression artifacts. </li></ul><h1 id="quantization-options">Quantization options</h1><ul><li><a target="_blank" rel="ugc" href="https://huggingface.co/Clybius/Chroma-fp8-scaled">Alternative option: FP8 Scaled Quant</a> (Format used by ComfyUI with possible inference speed increase)</li><li><a target="_blank" rel="ugc" href="https://huggingface.co/silveroxides/Chroma-GGUF">Alternative option: GGUF Quantized</a> (You will need to install ComfyUI-GGUF custom node)</li></ul><h1 id="special-thanks">Special Thanks</h1>A massive thank you to the supporters who make this project possible.<ul><li>Anonymous donor whose incredible generosity funded the pretraining run and data collections.
