Built-in Provider Configuration

Add a built-in provider

Open Options → API Providers, choose Add Provider, select a built-in provider, enter its API key when required, choose a model if the provider exposes one, and enable it. Use Test Connection before selecting the provider for translation, subtitles, or an AI feature.

Translation providers such as Google Translate, Microsoft Translate, DeepL, and DeepLX are suitable for translation features. LLM providers also support AI Smart Context, custom prompts, subtitle AI segmentation, and Custom AI Actions. Custom AI Actions and Notebase structured results require a model with reliable structured output.

Keep configuration current

Provider catalogs, model IDs, quota policies, and supported options change often. Select models from the extension UI or fetch them from a provider when that control is available; do not rely on a documentation list of default models. Use the provider's official documentation for pricing, regions, quotas, and API-key creation.

If a response is malformed, test the connection, confirm the selected model and API key, and review provider-specific options. Disable reasoning output when the provider exposes it and the model adds reasoning text before a structured response.
