[BUG]: v1alpha support for Live API in Google AKD Agents

[bhavyajoshi-mahindra]

How do I use 'gemini-live-2.5-flash-preview-native-audio-09-2025' in Google ADK agents. I am facing this issue:

from google.adk.agents import Agent
import os 

from google.genai.types import (
    GenerateContentConfig,
    HarmBlockThreshold,
    HarmCategory,
    SafetySetting,
)

from .prompts import AGENT_INSTRUCTION

genai_config = GenerateContentConfig(
    temperature=0.5
)

root_agent = Agent(
   name='agents',
   model="gemini-2.5-flash-native-audio-preview-09-2025",
   description="A helpful AI assistant.",
   instruction=AGENT_INSTRUCTION
)

I am getting this logs:

Starting client_to_agent_messaging task Connection closed: received 1008 (policy violation) models/gemini-live-2.5-flash-preview-native-audio-09-2025 is not found for API version v1alpha, or is not supported for bid; then sent 1008 (policy violation) models/gemini-live-2.5-flash-preview-native-audio-09-2025 is not found for API version v1alpha, or is not supported for bid.

Google AKD version : 1.19.0

The error occurs because ADK is using the Vertex AI model name format, but the model may not be available or the API version is incorrect. Fix it as follows: Set these environment variables:

GOOGLE_GENAI_USE_VERTEXAI=FALSE
GOOGLE_API_KEY=your_api_key_here
