## 2. Gemini Models
For Gemini models (e.g., `gemini-1.5-pro`, `gemini-2.0-flash`), the **GenAI SDK** (`google-genai`) is the **PREFERRED** method. The legacy `vertexai` SDK is still supported but GenAI SDK is recommended for new projects.

* **OpenMaaS**: Verify the model is available in your region. See [Model Availability by Location](https://docs.cloud.google.com/vertex-ai/generative-ai/docs/learn/locations#genai-open-models).

* **Source of Truth**: Always check [Gemini Model Locations](https://cloud.google.com/vertex-ai/generative-ai/docs/learn/locations#google-models) for the authoritative list.
* **Preview Models**: All Preview models (e.g., Gemini 2.0, experimental versions) are often **ONLY** available in the `us-central1` or `global` regions.
* **Stable Models**: (e.g., Gemini 1.5 Pro) Available in `us-central1`, `europe-west4`, and many other regions.
* **Preview Models**: All Preview models (e.g., Gemini 3.1, experimental versions) are often **ONLY** available in the `us-central1` or `global` regions.
* **Stable Models**: (e.g., Gemini 2.5 Pro) Available in `us-central1`, `europe-west4`, and many other regions.
* **Important**: If you get a 404/400 error, try switching your client location to `us-central1` or `global`.
2. **Enable Llama Models**: For **Llama 3.3** and **Llama 4**, you **MUST** enable the model in Model Garden before use. Go to the [Model Garden](https://console.cloud.google.com/vertex-ai/model-garden), search for the model card (e.g., "Llama 3.3 API Service"), and click **Enable**. Only then can you make inference requests.
