You Might Not Need 50 Diffusion Steps — Ziv Ilan, Nvidia

Jun 16, 2026 · 18:46

Nvidia's Ziv Ilan explains how combining quantization, caching, and step distillation enables near real-time video diffusion on a single Blackwell B200 GPU. Working with Black Forest Labs on Flux 2, dynamic quantization reduces memory and compute, caching skips redundant denoising steps, and distillation cuts steps from fifty to as few as one. The open-source FastGen repo packages these post-training and sharding techniques, achieving 10–200x speedups for real-time generation.

FLUX, Open Research, and the Future of Visual AI — Stephen Batifol, Black Forest Labs

May 8, 2026 · 22:32

Black Forest Labs (BFL), the team behind Stable Diffusion and Latent Diffusion, has released a series of open FLUX image models pushing toward visual intelligence. After FLUX.1 and the first open-source editing model FLUX Kontext (7–8 second edits), FLUX.2 achieved state-of-the-art text-to-image and multi-reference editing, and FLUX.2 Klein generates and edits in 300–500 milliseconds for near real-time use. BFL also published Self-Flow, a scalable self-supervised approach that trains multimodal models across images, video, audio, and actions without external encoders, outperforming baselines in all modalities. The episode explains how Self-Flow reduces artifacts (e.g., corrects text rendering and anatomy) and converges 70× faster with representation alignment. BFL’s roadmap includes world models that simulate geometry and interaction, aiming to train agents for robotics and automation.

ComfyUI Full Workshop — first workshop from ComfyAnonymous himself!

Jul 19, 2025 · 51:25

ComfyAnonymous and Yedrick Kosinski present ComfyUI, an open-source node-based canvas for generative AI that has become the top 150 most popular GitHub repos with 78,000 stars and 3 to 4 million active users. Started as a personal project in January 2023, it now supports image, video, audio, 3D, and text models, with 22,000 custom nodes from 3,000 developers. A key feature is embedding full workflows into generated files for easy sharing. The team discusses its story, including ComfyAnonymous's time at Stability AI and founding ComfyOrg, and addresses questions on CFG, VAEs, LoRAs, control nets, API nodes for remote generation, and future plans for cloud inference and improved onboarding.
