NewsNuva Lab × FastVideo
FastH3-Omni: Your Open Source “Unlimited Seedance” is here
TL;DR
- Open sourceThe open-weight, accelerated version of MiniMax H3 is now open to everyone, with full omni reference input (image, video, and audio, like Seedance 2.5) and 5 to 15 second video with synchronized audio in one pass.
- Built by Nuva Lab with FastVideoContinuing years of co-development. We ran it as an exclusive early-access partner during the preview, shipping to top performance ad agencies, animation studios, and entertainment companies.
- Our missionDemocratizing and scaling up content creation, with a founding team deeply rooted in the open-source community.
- 5.6–11.9× fasterLower end-to-end latency than MiniMax H3 on 8 NVIDIA GB200 GPUs, across 27 matched reference workloads measured by FastVideo.

What We Do
From open weights to production. Better with every iteration.
02
Customize
Adapt open models to your visual language, formats, and workflows while preserving quality and creative control. Fine-tuning and LoRA on MiniMax H3.
03
Deploy
Move from weights to a dependable production service with scalable infrastructure, observability, and hands-on support. Dedicated MiniMax H3 deployment.
04
Integrate
Connect video generation to your business systems through agents that generate assets, organize your library, and execute your production workflows. How the agents work.
05
Self-improve
We keep your deployment up to date with model and inference upgrades. Connected to your business systems, we use production feedback to refine agent strategies and improve end-to-end quality, speed, and cost. The feedback loop.
Open Weights
We believe open video models will remain a critical part of the production stack. The Nuva Lab team has contributed to open-source AI for years. We optimize open-weight models for production today and will continue supporting and contributing to the models that come next.

FastH3-Omni Open Weights
LatestNuva Lab built this open-weight, accelerated version of MiniMax H3 with FastVideo: image, video, and audio references in, 5 to 15 second video with synchronized audio out.
Optimized FastH3 Serving with Uniserve
An optimized serving runtime for FastH3 on NVIDIA Blackwell. A 10-second clip with audio renders in 6.3 s on eight GB200 GPUs (5.4 s with optional NVFP4), with 1.2–1.7× lower median latency and 15–45% higher throughput than other open-source serving stacks. Already serving production traffic at Nuva Lab.
FastH3 8-Step V2
The eight-step FastH3 checkpoint that production serving now runs on, trained with data-free DMD2 distillation and 80% sparse video attention.
FastH3 Goes Local
The FastVideo ecosystem brings FastH3 to NVIDIA DGX Spark and Apple Silicon for local video generation.
MiniMax H3 on vLLM-Omni
vLLM-Omni details the complete MiniMax H3 serving stack and its integration with FastVideo's four-step FastH3.
FastH3 Preview v1
Open-weight, four-step sparse-distilled MiniMax H3, developed with FastVideo and NVIDIA collaborators and grounded in production workloads with Nuva Lab.
