Run AI Video Generation
Locally. Without the Pain.
OpenSora-UI is a clean interface for running Open-Sora and other open-source video models on your own GPU. No complex setup. No cloud limits. No subscription.
Running Open-Sora is unnecessarily hard.
Before you can generate a single frame, you're stuck configuring conda environments, resolving CUDA version mismatches, chasing dependency conflicts, and deciphering multi-page install guides.
Four steps. No terminal required.
OpenSora-UI handles all the dependency management, CUDA configuration, and environment setup automatically. You click install. You pick a model. You generate video. That's it.
Everything you need. Nothing you don't.
OpenSora-UI is purpose-built for running open-source video models locally — not adapted from something else.
One-Click Install
No conda, no pip conflicts, no CUDA headaches. The installer handles all dependencies and environment configuration automatically.
Model Manager
Browse, download, and switch between Open-Sora, Wan, Mochi, HunyuanVideo, and more from a unified library view.
Job Queue
Queue multiple generation jobs and let them run back-to-back. Track progress, cancel jobs, and review history — all in one place.
Local GPU Acceleration
Full CUDA support out of the box. OpenSora-UI automatically detects your GPU and configures optimal settings for your hardware.
Clean Interface
Prompt, settings, preview, queue — everything is exactly where you expect it. Designed for repeated daily use, not just demos.
Fully Offline
Once models are downloaded, nothing phones home. No analytics, no license checks, no cloud dependency. Your GPU, your data, your control.
Up and running in minutes.
Install OpenSora-UI
Download the installer for your platform. Run it once. Dependencies are handled automatically — no terminal required.
Windows · macOS · LinuxRun System Check
OpenSora-UI scans your GPU, CUDA version, and available memory. It tells you exactly which models your system can run.

Open-Sora · Wan · Mochi · HunyuanVideoGenerate Video
Write your prompt, set your resolution and frame count, hit Generate. Your GPU does the work. No cloud, no queue, no wait.
Runs 100% locally on your hardwareOwn your compute.
Cloud video generation tools rent you time on hardware you don't own. Local generation means the power is yours.
No credits. No limits.
Cloud AI video tools charge per second of video or per generation. With OpenSora-UI, your GPU runs as many jobs as you want, forever.
No queue. Instant start.
Cloud services have processing queues that can make you wait minutes — or hours during peak times. Local means you start the moment you click Generate.
No subscription.
Buy once, use forever. No monthly fees, no seat licenses, no pricing tiers. The license is yours for as long as you need it.
Full privacy.
Your prompts, your videos, your ideas — none of it leaves your machine. Nothing is sent to a server. There is no telemetry.
Unlimited runs.
Test every setting. Iterate fast. Run 50 generations in an afternoon. When your GPU is the only limit, you can experiment freely.
Simple pricing. No surprises.
One license. One payment. No subscriptions, no per-video fees, no seat limits.
Pay once. Use forever.

Models are not included. They are downloaded separately from official sources (HuggingFace, GitHub). Open-Sora is an open-source project by HPC-AI Tech.
Common questions.
Everything you need to know before purchasing. More in the docs.
No. Open-Sora is an open-source AI video generation model developed by HPC-AI Tech. OpenSora-UI is a completely separate commercial product — a graphical desktop application that makes it easier to install and run Open-Sora and other open-source models on your own computer. We are not affiliated with HPC-AI Tech.
Yes. AI video generation is computationally intensive and requires a CUDA-capable NVIDIA GPU. We recommend a minimum of 8 GB VRAM for smaller models (Open-Sora at lower resolutions), and 16–24 GB VRAM for larger models like HunyuanVideo or high-resolution generation. AMD GPU support via ROCm is experimental.
No. The $29 license covers the OpenSora-UI application only — the installer, the interface, and the model manager. The actual AI models (Open-Sora, Wan, Mochi, etc.) are open-source and free, and are downloaded directly from their official sources (HuggingFace, GitHub) through the app. You never pay for the models themselves.
No. OpenSora-UI is a one-time purchase. You pay once and own the license permanently. There are no monthly fees, no usage limits, no seat charges, and no renewal required. Updates within the current major version are free.
Yes, once you have downloaded the models you want to use, OpenSora-UI works entirely offline. There is no internet connection required for generation. The only time internet is needed is for downloading models — and that uses official public sources (HuggingFace).
Yes. All models supported by OpenSora-UI are open-source projects released under permissive licenses (Apache 2.0, etc.) that explicitly allow personal and commercial use. OpenSora-UI itself is a commercial software wrapper. Always check the specific license of each model for your use case, particularly for commercial output.
OpenSora-UI supports Windows 10/11 (x64) with NVIDIA GPU. macOS and Linux support is in active development. All platforms require an NVIDIA CUDA-capable GPU. Metal (Apple Silicon) support is planned for a future release.
We provide documentation, a GitHub issues tracker for bug reports, and direct email support for license holders. We actively maintain the software and release updates to keep pace with new model versions and upstream changes.
