Livestream Update: @MiniMax_AI H3: A New Open-Weight Video Model, Live in ComfyUI MiniMax H3 is an open-weight, general-purpose multimodal video generation model that works across text, images, video, and audio. In ComfyUI, you can use H3 for text-to-video, image-to-video, first- and last-frame generation, and reference-driven creation. H3 jointly generates the visuals and synchronized stereo audio, including dialogue, sound effects, ambience, and music, rather than adding audio afterward. The open-weight H3 checkpoints support clips up to 15 seconds at 768p. MiniMax’s hosted H3 model also supports generation at up to 2K resolution. During the stream, we’ll test the model live and discuss how H3 brings multiple generation tasks into one architecture, how its high-compression video representation improves efficiency, and what developers should know when setting it up locally through ComfyUI. What we'll cover: →MiniMax H3: open weights, native stereo audio, up to 2K/15s clips →Live demo →How H3 got small enough to run on consumer hardware →ComfyUI workflow templates for H3 →Local workflow: use the H3 Context-IR API ( generate locally at 768p, and use the H3 Regenerate-2K API

MiniMax H3 is native in ComfyUI, day zero with the weights. Model highlights: → Text-to-video, prompt only → Image-to-video → First-and-last-frame - control the opening frame, the closing frame, or both → Reference-to-video - carry a subject, a motion, or a voice through the clip → In-place editing - modify a shot you already have instead of regenerating it The capability @MiniMax_AI leads with is multimodal context understanding, and it's what collapses those five tasks into one model. H3 takes images, audio, and video together and resolves them against a prompt that explains how they relate. Download the workflows & learn more in our blog 👇

HappyHorse 1.1 is now available in ComfyUI as a Partner Node. Native audio. Multi-character consistency. Cinematic framing. All in one render pass. What's new in 1.1: → Dynamic expressiveness: Smoother motion, no more stiff movement → Enhanced R2V: Up to 9 reference images per generation → Multi-character consistency: Each character holds their look, zero cross-contamination → Flexible char × scene: Characters stay consistent as backgrounds change → Better instruction following: Handles 2,500+ char prompts, 6–8 scenes in one pass → Natural skin: Fixes shiny skin and over-sharpening for close-up commercial work → Cinematic language: Shot-reverse-shot, tracking shots, cohesive transitions → Upgraded audio: Tighter dialogue + SFX sync with emotional performance layered in Click the link below for the blog & the workflow 👇
