- * Fetches available models from a provider using the SDK's fetch infrastructure.
- *
- * This function uses createTimeoutFetch() which wraps Tauri's HTTP plugin,
- * making it compatible with Tauri's sandboxed environment and consistent
- * with how the Vercel AI SDK providers make their API calls.
- *
- * @param providerType - The provider to fetch models from
- * @param baseUrl - Optional custom base URL (for local LLMs, custom deployments, etc.)
- * @param apiKey - Optional API key for authentication (required for some providers)
- * @returns Array of model IDs available from the provider
- * @throws Error if the provider doesn't support model fetching or if the request fails
- *
- * @example
- * ```typescript
- * // Fetch OpenRouter models
- * const models = await fetchModelsFromProvider('openrouter');
- *
- * // Fetch OpenAI models with API key
- * const models = await fetchModelsFromProvider('openai', undefined, apiKey);
- *
- * // Fetch from local Ollama instance
- * const models = await fetchModelsFromProvider('openai', 'http://localhost:11434/v1');
- * ```
+ * Fetches available models from a provider.
