# Gemini 3.8 Live

Gemini 3.8 Live (`gemini-3.8-live`) is our flagship low-latency, audio-to-audio
model engineered for real-time dialogue, rapid turn-taking, and voice-first AI
applications. It features acoustic nuance detection, affective dialogue,
proactive audio, and support for both synchronous and asynchronous function
calling.

For complex agentic tasks requiring multi-step reasoning and configurable
thinking budgets, see
[Gemini 3.8 Live Extended Thinking](/docs/models/gemini-3.8-live-extended-thinking).

## Migrating from Gemini 3.1 Flash Live  {% id="migrating" %}

Gemini 3.8 Live is the generally available (GA) successor to
`gemini-3.1-flash-live-preview`. When migrating to `gemini-3.8-live`, note the
following improvements and behavioral updates:

*   **Model string**: Update your model string from
  `gemini-3.1-flash-live-preview` to `gemini-3.8-live`.
*   **Asynchronous function calling**: `gemini-3.8-live` supports both
  synchronous and asynchronous (`NON_BLOCKING`) function calling, allowing
  your application to execute background tools without pausing the
  conversation. See
  [Asynchronous function calling](/docs/live-api/tools#async-function-calling).
*   **Proactive audio and affective dialogue**: Both features are now supported
  on `gemini-3.8-live`. You can enable proactive responses so the model only
  chimes in when relevant, and use affective dialogue for emotion-aware
  responses. See
  [Proactive audio](/docs/live-api/capabilities#proactive-audio) and
  [Affective dialogue](/docs/live-api/capabilities#affective-dialog).
*   **Thinking level**: `gemini-3.8-live` operates exclusively at
  `thinkingLevel="MINIMAL"` to guarantee the lowest possible
  time-to-first-audio. If your application requires `LOW`, `MEDIUM`, or `HIGH`
  thinking levels, use
  [`gemini-3.8-live-extended-thinking`](/docs/models/gemini-3.8-live-extended-thinking).
  See [Thinking in the Live API](/docs/live-api/thinking).
*   **Client content**: `send_client_content` is supported for appending text or
  structured context turns mid-session as well as seeding initial history. See
  [Incremental content updates](/docs/live-api/capabilities#incremental-updates).

For a detailed feature comparison across all Live API models, see the
[Model comparison](/docs/live-api/capabilities#model-comparison) table in the
capabilities guide.
