 <Callout type="note" title="Notes:">
 
-- A gemini-pro model or `gemini-pro-vision` are required in your list for attaching images.
+- `gemini-flash-latest`, `gemini-flash-lite-latest`, and `gemini-pro-latest` point to the latest available model for each variant, so they are usually safer choices over time as Google deprecates older fixed model IDs.
 - Using LibreChat, PaLM2 and Codey models can only be accessed through Vertex AI, not the Generative Language API.
   - Only models that support the `generateContent` method can be used natively with LibreChat + the Gen AI API.
-- Selecting `gemini-pro-vision` for messages with attachments is not necessary as it will be switched behind the scenes for you.
-- Since `gemini-pro-vision` does not accept non-attachment messages, messages without attachments are automatically switched to use `gemini-pro` otherwise Google responds with an error.
 - With the Google endpoint, you cannot use both Vertex AI and Generative Language API at the same time. You must choose one or the other.
-- Some PaLM/Codey models and `gemini-pro-vision` may fail when `maxOutputTokens` is set to a high value. If you encounter this issue, try reducing the value through the conversation parameters.
