### 3. AI Providers
To configure custom AI providers:
1. Update the providers in [`packages/ai/src/chat/providers.ts`](https://github.com/onlook-dev/onlook/blob/main/packages/ai/src/chat/providers.ts). We already support Anthropic and OpenRouter as examples. You can follow the same format to add a new provider.

2. Update the usages by searching for [`initModel`](https://github.com/search?q=repo%3Aonlook-dev%2Fonlook+%22await+initModel%22&type=code)
3. Update your API keys in the `apps/web/client/.env` file to the provider's expected API keys.

Built-in providers:
- **OpenRouter** (default) — access to multiple models via a single API key
- **[MiniMax](https://platform.minimaxi.com)** — MiniMax-M2.5 models with 204K context window

Note: We support any provider from the [AI SDK providers](https://ai-sdk.dev/providers/ai-sdk-providers). You can add a custom provider by following these AI SDK provider guides: [OpenAI compatible](https://ai-sdk.dev/providers/openai-compatible-providers/custom-providers) and [Community](https://ai-sdk.dev/providers/community-providers/custom-providers).

Update @ai-sdk/openai-compatible to a valid version.

Version 1.0.34 does not exist in the npm registry. The latest stable versions are 2.0.8 and 2.0.9. Update the dependency to one of these versions or the latest available version that meets the project requirements.

In `@packages/ai/package.json` at line 36, The package.json entry for the
dependency "@ai-sdk/openai-compatible" uses a nonexistent version ("^1.0.34");
update that dependency in packages/ai/package.json by replacing the version
string with a valid released version such as "^2.0.9" (or "^2.0.8" if preferred)
so the dependency resolves correctly during installs.
