## Tips and Notes

*   **Prompt Caching (Manual Activation Required):**
    *   Prompt caching is available for supported Gemini 2.5 models.
    *   However, for the **Google Gemini provider**, caching is **not enabled by default**.
    *   You **must manually check** the "Enable Prompt Caching" box in the provider settings to activate it.
    *   **Reason:** This manual step is a temporary workaround due to potential response delays sometimes observed with Google's caching mechanism when accessed directly via this provider.
*   **Pricing:**  Gemini API usage is priced based on input and output tokens. Refer to the [Gemini pricing page](https://ai.google.dev/pricing) for detailed information.
