OhMyGame ships without a model. On first launch, it walks you through setup.
1. Get started
Language and appearance follow your system. You can change them at any time in Settings.
2. Choose your AI
You can use the built-in OhMyGame agent with a model provider, signing in or pasting an API key. You can also use a Claude Code, Codex or OpenCode CLI you already have. Use + to add a custom or local endpoint, or Skip this step to move on without a model.
A language model alone can design and build a game. To generate media, connect the matching provider in Settings → Providers:
| To make | Connect |
|---|---|
| Design docs, code, playtests | Any language model provider |
| Images and sprites | Codex CLI (local sign-in), OpenAI (API key), OpenRouter, or Volcengine Ark / BytePlus ModelArk |
| Video | OpenRouter, Volcengine Ark / BytePlus ModelArk, or MiniMax |
| 3D models, rigging, animation | Meshy, Tripo, or Hyper3D (capabilities vary by provider) |
| Voice, sound effects, music | Doubao Speech and Seed Audio (Volcengine) |
Signing in with ChatGPT doesn’t cover OpenAI’s image API. Add a separate API key in the OpenAI provider’s Image models section, or use the Codex CLI image provider, which uses your local Codex sign-in.
3. Choose where to start
Describe a game in the prompt box on the home screen, start a blank project, or import a folder you already have. If you’re new, start with a Web Game: it’s tuned for the browser, and it previews, playtests and publishes without extra setup.
Good to know
- Web search works without setup.
- Making games locally needs no account. Sign in only to publish.
- To see this setup again, open Settings → About → View getting started.
