Google began rolling out Gemini 3.7 Flash as a selectable model in Search's AI Mode on August 14. The option is available globally in English to Google AI Pro and Ultra subscribers, but Google has not said it will replace AI Mode's default model or become available to the free tier.
Google added Gemini 3.7 Flash as a selectable model in Search's AI Mode on August 14, one day after introducing the model for coding and agent workloads. Robby Stein, Google's vice president of product for Search, said the rollout is global in English for Google AI Pro and Ultra subscribers. Users can open the model menu with the plus icon in AI Mode's Ask anything bar.
A paid option, not a new default
Google describes Gemini 3.7 Flash as better at following instructions and understanding user intent. Search Engine Journal reported that the model appears under the Gemini 3 section of AI Mode's menu alongside Auto and Pro. The announcement does not say that 3.7 Flash will become AI Mode's default model, join its automatic routing system or reach free users.
That distinction matters. The rollout gives eligible subscribers another model they can choose; it does not establish that every AI Mode response now uses Gemini 3.7 Flash. Google's AI Mode help page still described Fast and Pro when retrieved on August 14 and had not yet documented the new option, so availability may also vary while the rollout propagates.
Separate from the August 13 model release
Google introduced Gemini 3.7 Flash on August 13 as a workhorse model for coding and agents. The company said the release improves instruction following, multi-step planning and tool use, and made it available across developer and enterprise products as well as Gemini Spark for eligible subscribers. The Search announcement is a distinct product integration rather than a second model launch.
What to watch in AI Mode
For practitioners who test AI Mode, the selector creates a straightforward way to compare the same query across 3.7 Flash, Auto and Pro. Differences in answer structure, source selection or citations can be observed, but they should not be attributed to the model alone without repeated tests because Search results, account state and staged rollout conditions may also change. The practical impact is therefore bounded: paid English-language users get an additional model choice, while the default experience and broader availability remain unconfirmed. SEO and publisher teams should not infer a platform-wide traffic or citation shift from this rollout alone.
