Hey All,

We heard your feedback and this gemini-2.5-flash-native-audio-preview-09-2025 model is much better at function calling and has reduced audio cutoffs. Can you please try again with the new model and let us know what you think?

Thank you!

Hello @chunduriv , we’re using the new gemini-2.5-flash-native-audio-preview-09-2025 and it seems to be having the same issues, if not worse. We are able to reproduce this on https://aistudio.google.com/live. Steps to reproduce:

  1. Go to live api studio: https://aistudio.google.com/live

  2. Enable ‘Function calling’

  3. Click ‘edit’ and go to the code editor

  4. Paste the below json:
    ```
    [
    {
    “name”: “sendProductImageLinksTool”,
    “description”: “Sends product images to the chat UI for display. Use this when showing product photos, comparisons, or visual references.”,
    “parameters”: {
    “type”: “object”,
    “properties”: {
    “images”: {
    “type”: “array”,
    “description”: “Array of image objects with URL and pronounceable name (max 10 images)”,
    “items”: {
    “type”: “object”,
    “properties”: {
    “url”: {
    “type”: “string”,
    “description”: “The image URL”
    },
    “pronounceableName”: {
    “type”: “string”,
    “description”: “A short, easy-to-pronounce name for this specific image (e.g., ‘Nike Pegasus 41 - Side View’, ‘iPhone 15 - Front’)”
    }
    },
    “required”: [
    “url”,
    “pronounceableName”
    ],
    “propertyOrdering”: [
    “url”,
    “pronounceableName”
    ]
    }
    },
    “collectionTitle”: {
    “type”: “string”,
    “description”: “A generic title for the collection of images being shown (e.g., ‘Nike Running Shoes’, ‘iPhone 15 Series’, ‘Washing Machine Comparison’)”
    }
    },
    “required”: [
    “images”,
    “collectionTitle”
    ],
    “propertyOrdering”: [
    “images”,
    “collectionTitle”
    ]
    }
    }
    ]
    ```

  5. Save

  6. Type “Show me images of iPhone” (or speak it)

  7. You’ll see “Something went wrong” (Gemini internal error) - if it works, refresh the page (not just the app) and try again
