Happy Horse in the Video Studio
The most uncensored model in the building.
Happy Horse specializes in realistic humans at 1080p and carries the studio's Most Uncensored badge - an open-weights model hosted with no prompt moderation layer, for the briefs everything else declines. In the same picker as Seedance, Veo and Kling when you want the mainstream lane.

Skip the setup
Happy Horse without APIs, queues, or GPUs.
Happy Horse ships developer-shaped: endpoints, checkpoints, request schemas. OpenGradient runs it as a product - open the studio, pick the model, type the prompt. Same weights, none of the plumbing.
The DIY route
Self-hosting means serious GPU hardware and pipeline babysitting; API routes mean keys, payloads and output handling before your first frame.
The billing maze
Per-second GPU pricing across providers makes a simple question - what does this clip cost? - surprisingly hard. The studio shows the price before you render.

Why run Happy Horse here
Full studio around the model
Happy Horse renders realistic human subjects at 1080p by default and is the studio's most permissive model. Style presets, first/last-frame control on supported models, and 2x/4x upscaling are built in.
No provider-side prompt moderation
This family runs as open-weights deployments without a moderation layer on top - badged Uncensored in the picker, 18+ capabilities behind their own gate, illegal content banned.
Private by architecture
Prompts route through the anonymity layer, and video share links expire 24 hours after generation.

Questions, answered
Frequently asked
- What is Happy Horse best at?
- Realistic human subjects and maximum permissiveness. It's the model to reach for when the brief involves people and mainstream tools keep bouncing it - within the published content rules and the 18+ gate.
- What does a clip cost?
- Per-clip prices depend on model and duration and are shown before you generate. 1,000 credits = $1; packs from $10; free to start.
- Is the model list here current?
- Yes - the chips above are rendered from the studio's live catalog at build time, so this page always reflects what's actually in the picker.
