# Gemini 3.7 Flash Is Now Available

Google released Gemini 3.7 Flash, and we have refreshed the whole Gemini lineup in AI Data Stream: 3.7 Flash and 3.1 Pro replace the old previews, with automatic migration and no action needed on your part.

Google has released [Gemini 3.7 Flash](https://blog.google/innovation-and-ai/models-and-research/gemini-models/introducing-gemini-3-7-flash/), calling it their most intelligent workhorse model yet, and it is generally available - no more preview labels. We have taken the opportunity to refresh the entire Gemini lineup in AI Data Stream.

## What Changed for You

**Nothing you need to do.** AI Data Stream automatically migrates your model selection:

- **Gemini 3 Flash (preview)** → **Gemini 3.7 Flash**
- **Gemini 3 Pro (preview)** → **Gemini 3.1 Pro**

Google retired the Gemini 3 Pro preview earlier this year and deprecated the Gemini 3 Flash preview, so both have been removed from the picker. Your API key, settings, and conversations all remain the same.

We have also added **Gemini 3.5 Flash Lite** as the new fastest option. **Gemini 2.5 Flash Lite is not being migrated** - it stays in the picker as the cheapest option, so nobody's costs change without them choosing it.

## Pricing

As always, AI Data Stream is bring-your-own-key: you are billed by Google directly at their published rates.

- **Gemini 3.7 Flash** launches with introductory pricing of **$0.75 / $3.75** per million input / output tokens through **31 December 2026**. From 1 January 2027 the standard price is **$1.50 / $7.50**.
- **Gemini 3.1 Pro** is **$2.00 / $12.00** per million tokens for prompts up to 200k tokens ($4.00 / $18.00 above that).
- **Gemini 3.5 Flash Lite** is **$0.30 / $2.50** per million tokens.
- **Gemini 2.5 Flash Lite** remains the budget choice at **$0.10 / $0.40** per million tokens.

## What Is New in Gemini 3.7 Flash

Gemini 3.7 Flash is built for complex multi-step work - exactly the kind of tool-driven analysis AI Data Stream runs when it queries your connected data sources. It brings a 1M-token context window, tunable thinking levels, and substantially improved agentic reliability over the 3 Flash preview it replaces. It is a stable, generally available model, which also means Google Search grounding is supported - as it now is across our whole Gemini lineup.

With this update, the complete Google model lineup in AI Data Stream is:

- **Gemini 3.7 Flash** - Best balance, the recommended default
- **Gemini 3.1 Pro** - Most advanced, for the most demanding analysis
- **Gemini 2.5 Pro** - Previous-generation reasoning model
