FLUX.1: 12B Parameter Rectified Flow Transformer for High-Fidelity Image Generation
Architected FLUX.1, an open-weights 12B parameter multimodal diffusion transformer utilizing rectified flow matching, achieving unmatched prompt adherence, typography generation, and photographic realism.
12B model footprint requires 24GB+ VRAM or 8-bit/4-bit quantization (NF4) for local inference on consumer hardware.
Context: 12B parameter multimodal Diffusion Transformer (MMDiT), rectified flow matching, rotary positional embeddings.

Lead author of the landmark CVPR 2022 paper introducing Latent Diffusion Models (LDMs), shifting diffusion training from raw pixel space into a compressed latent perceptual space, unlocking consumer GPU diffusion synthesis.
Fine spatial details (e.g., distant human hands or miniature typography) can suffer perceptual compression loss in the VAE latent space.
Context: Autoencoder latent space (8x downsampling), cross-attention conditioning, UNet denoising backbone.
