TensorRT LLM VisualGen speeds up FLUX 3 Image Klein on Blackwell GPUs

Nvidia developers explain how to configure and optimize the FLUX 3 Image Klein diffusion model using TensorRT LLM VisualGen on Blackwell GPUs. The tutorial demonstrates how fused kernels, NVFP4 quantization, attention optimizations like VC-Attention and Sol-Attention, caching, and multi-GPU Ulysses parallelism combine to deliver up to 3.46x faster text-to-image and 4.45x faster image-to-image generation compared to uncompiled BF16 inference.
