Nucleus-Image is a brand new model created by NucleusAI. It's a sparse MoE diffusion transformer with 17b-a2b (17b total parameters, 2b active parameters) and the text encoder is based on Qwen3-VL-8b and VAE is from Qwen-Image. In BF16 the total model weights are 34GB + 16GB = 50GB. FP8 Transformer only 17GB, so this might work on a 3090. Good 4-bit of the transformer may be around 10GB and work on 16GB cards. Still there are other options - it being an MoE one may attempt to prune some experts. It's a base model. It was not post trained, no DPO, no RL, no preference tuning.
