# Make videos with a free agent
> HyperFrames is free; the agent is the only cost. Use OpenCode's free models in the Studio app, or a model on your own computer, and see how open models score.
HyperFrames costs nothing. What you pay for is the AI agent that writes the video, and that can be free too.
## Same prompt, paid model and open model
In HeyGen's [Code2Video benchmark](https://www.heygen.com/research/introducing-code2video-benchmark), models wrote
videos with the HyperFrames skills from 168 briefs and were ranked against each other. The open-weight models
(Qwen 3.8 Max, DeepSeek V4.1 Flash, Kimi K3, GLM 5.3) all landed within 50 Elo points of first place. The same prompt,
given to a paid model and to an open one:
**Claude Fable 5**
**DeepSeek V4 Flash**
The top models are still better at the hard parts: timing, composition, finish. For a first draft, a social post or
learning the tool, an open model is often enough.
## In the Studio app: OpenCode
[Connect an agent](https://hyperframes.heygen.com/studio-app/connect-your-agent.md) and choose **OpenCode**. The app installs it, and it runs free
models with no sign-in. It needs **Full access**, and the app asks to turn it on the first time.
## On your own computer
OpenCode can also use a model running locally, so nothing leaves your machine and nothing is billed. With
[Ollama](https://ollama.com) running, OpenCode finds its models by itself; pick one that supports tools. See [OpenCode's model docs](https://opencode.ai/v2/docs/models).
Local models are slower and weaker than the hosted ones, so start with short videos.
## What else is free
Rendering, previews, Kokoro voices, background removal and the bundled sound effects run on your computer at no
cost, and so does transcription when your own agent does it. The Studio app is free with a free HeyGen account. HeyGen's voices, avatars and generated clips use HeyGen credits;
everything else in a video is code. See [free or HeyGen quality](https://hyperframes.heygen.com/guides/voice-and-audio.md#free-or-heygen-quality).
