# Gemini 3 Pro Thinking Level

> Migrate the pinned thinking-level example to Gemini 3.1 Pro Preview and stream the async response.

<Warning>
  Google shut down Gemini 3 Pro Preview on March 9, 2026. The pinned `gemini-3-pro-preview` ID currently aliases to `gemini-3.1-pro-preview`; replace it explicitly before running.
</Warning>
