# Vertex AI Gemini Live - Realtime API
Use Vertex AI's Gemini Live API (BidiGenerateContent) through LiteLLM's unified `/realtime` endpoint, which speaks the OpenAI Realtime protocol.
| Feature | Supported |
|---------|-----------|
| Proxy (`/realtime`) | ✅ |
| Voice in / Voice out | ✅ |
| Text in / Text out | ✅ |
| Server VAD | ✅ |
| Output transcription | ✅ |
## Setup
### 1. Auth
LiteLLM uses your Google Cloud credentials (OAuth2 Bearer token), not an API key.
```bash
gcloud auth application-default login
```
Or set a service-account key file:
```bash
export GOOGLE_APPLICATION_CREDENTIALS=/path/to/sa-key.json
```
### 2. Proxy config
```yaml
model_list:
- model_name: vertex-gemini-live
litellm_params:
model: vertex_ai/gemini-2.0-flash-live-001
vertex_project: your-gcp-project-id
vertex_location: us-east4 # or any supported region, or "global"
general_settings:
master_key: sk-your-key
```
### 3. Start the proxy
```bash
litellm --config config.yaml --port 4000
```
## Usage
### Python (websockets)
```python
import asyncio
import json
import websockets
PROXY_URL = "ws://localhost:4000/realtime?model=vertex-gemini-live"
API_KEY = "sk-your-key"
async def main():
async with websockets.connect(
PROXY_URL,
additional_headers={"api-key": API_KEY},
) as ws:
# Wait for session.created
event = json.loads(await ws.recv())
print(f"session.created: {event['session']['id']}")
# Send a text message
await ws.send(json.dumps({
"type": "conversation.item.create",
"item": {
"type": "message",
"role": "user",
"content": [{"type": "input_text", "text": "Say hello in one sentence."}],
},
}))
# Collect the response
async for raw in ws:
ev = json.loads(raw)
t = ev.get("type", "")
if t == "response.text.delta":
print(ev.get("delta", ""), end="", flush=True)
elif t == "response.done":
print("\n[done]")
break
asyncio.run(main())
```
### Node.js
```js
const WebSocket = require("ws");
const ws = new WebSocket(
"ws://localhost:4000/realtime?model=vertex-gemini-live",
{ headers: { "api-key": "sk-your-key" } }
);
ws.on("open", () => {
ws.send(JSON.stringify({
type: "conversation.item.create",
item: {
type: "message",
role: "user",
content: [{ type: "input_text", text: "Say hello." }],
},
}));
});
ws.on("message", (data) => {
const ev = JSON.parse(data);
if (ev.type === "response.text.delta") process.stdout.write(ev.delta);
if (ev.type === "response.done") ws.close();
});
```
### OpenAI SDK (Python)
```python
import asyncio
from openai import AsyncOpenAI
client = AsyncOpenAI(
base_url="http://localhost:4000",
api_key="sk-your-key",
)
async def main():
async with client.beta.realtime.connect(
model="vertex-gemini-live"
) as conn:
await conn.session.update(session={"modalities": ["text"]})
await conn.conversation.item.create(
item={
"type": "message",
"role": "user",
"content": [{"type": "input_text", "text": "Say hello."}],
}
)
async for event in conn:
if event.type == "response.text.delta":
print(event.delta, end="", flush=True)
elif event.type == "response.done":
print()
break
asyncio.run(main())
```
## Voice in / Voice out
For a complete voice example see [`voice_realtime_test.py`](https://github.com/BerriAI/litellm/blob/main/voice_realtime_test.py).
Key settings for audio:
- Microphone input: **16 kHz** PCM16 (`audio/pcm;rate=16000`)
- Speaker output: **24 kHz** PCM16 (Vertex AI returns audio at 24 kHz)
- Server VAD is enabled by default with 800 ms silence threshold
```python
# session.update with server VAD — the proxy ignores this for Vertex AI
# because VAD is already configured in the initial setup message.
await ws.send(json.dumps({
"type": "session.update",
"session": {
"modalities": ["audio"],
"turn_detection": {"type": "server_vad", "silence_duration_ms": 800},
},
}))
```
## Supported OpenAI Realtime Events
**Client → Proxy (→ Vertex AI)**
| OpenAI event | Notes |
|---|---|
| `input_audio_buffer.append` | Forwarded as `realtime_input.audio` |
| `conversation.item.create` | Forwarded as `realtime_input.text` |
| `session.update` | Silently ignored — Vertex AI does not support mid-session reconfiguration |
| `response.create` | Silently ignored — Vertex AI responds automatically after each turn |
**Vertex AI → Proxy (→ Client)**
| OpenAI event emitted | Vertex AI source |
|---|---|
| `session.created` | Synthesized after `setupComplete` |
| `response.text.delta` | `serverContent.modelTurn.parts[].text` |
| `response.audio.delta` | `serverContent.modelTurn.parts[].inlineData` |
| `response.audio_transcript.delta` | `serverContent.outputTranscription.text` |
| `conversation.item.input_audio_transcription.completed` | `serverContent.inputTranscription.text` |
| `response.done` | `serverContent.turnComplete` |
## Limitations
- `session.update` is not forwarded (Vertex AI only accepts one setup message per connection).
- Tool calling / function calling is not yet supported.
- Audio transcription requires `outputAudioTranscription: {}` to be set in the initial setup (done automatically by LiteLLM).
