* docs: an FAQ, a free-agents page, and 30 Days as a numbered list The FAQ answers the questions people ask the docs assistant most, each linking to its page. Make videos with a free agent shows OpenCode's free models in the Studio app, local models through Ollama, and how open models scored in Code2Video. 30 Days of HyperFrames becomes one numbered row per lesson with its film on hover, and drops a link to a section that no longer exists. * docs: 30 Days previews honour reduced motion and have a play button Hovering a lesson started its film even with reduced motion on, and keyboard and touch visitors had no way to play it. Hover previews now follow the setting (read on the first render, and stopped if it turns on), and each film is a button that plays and pauses on purpose. * docs: 30 Days plays one chosen film at a time Choosing a lesson film pauses the one chosen before, so every button matches its film, and other rows do not preview while a film plays. * docs: one film at a time across the whole 30 Days page The page mounts three lesson lists, and each only paused its own films. A chosen film now plays with sound, and any unmuted start on the page makes every list stop its own films and drop its choice; previews stay muted and wait while a film with sound plays. * docs: 30 Days list in the docs palette The lesson list used fixed black and white tints; its rules, numbers, lines and film backgrounds now use the palette tokens, so they match the beige ground and the Night theme.

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:
|
|
|
|
<div className="hf-versus">

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](/studio-app/connect-your-agent) 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](/guides/voice-and-audio#free-or-heygen-quality).
