The no-code Atlas Cloud alternative
Uncensored open video models, minus the API.
Atlas Cloud serves open-weights video models to developers. OpenGradient's Video Studio runs the same uncensored open models - the Wan family and Happy Horse - as a finished product: type a prompt, pick duration and aspect, generate. Private by architecture, one credit balance.

The last mile of open models
Open weights still arrive developer-shaped.
The best uncensored video models are open-weights - which means they ship as endpoints and checkpoints, not products. Between you and the first clip sits an API key, a request schema, and output handling. That's the gap a studio closes.
Endpoints, not experiences
Hosted open models still speak JSON: parameters, polling, storage. The model is uncensored; the workflow is unforgiving.
Mainstream studios won't run them
Polished consumer video tools moderate prompts at the door and don't carry unrestricted open models at all - so the models that will say yes have the worst UX.
The questions people actually bring here
Here's how OpenGradient is different
The unrestricted lineup, product-shaped
Uncensored open models, first-class
Wan 2.5, 2.6 and 2.7, plus Happy Horse 1.0/1.1 - open-weights models hosted without provider-side prompt moderation, clearly badged in the picker.
Full studio around them
Text-to-video and image-to-video, first/last-frame chaining, style presets, upscaling to 4K - and the mainstream models (Veo, Kling, Seedance) in the same picker for when you want them.
Private by architecture
Prompts pass through an anonymity layer; share links expire after 24 hours. What you make is your business.

The anonymity layer
The models that say yes, with privacy to match.

Questions, answered
Frequently asked
- Are these really the same models?
- Yes - the studio's unrestricted tier runs open-weights models of the same families the developer platforms host: the Wan line and Happy Horse. The picker always shows the current versions and badges.
- What are the content rules?
- Unrestricted means no provider-side prompt moderation on the open models - not no rules. Illegal content is banned, and explicit 18+ capabilities sit behind their own gate. The full policy is one click from every generation surface.
- Why not just use the API?
- If you're building an app, do. If you're making clips, the studio saves you the integration and adds the parts an API can't: visual controls, galleries, chaining, upscaling and privacy by default.
