The new upgrade allows users to ask follow-up questions in search.

Google Search is getting its biggest revamp in 25 years with a Gemini 3.5 Flash integration, as AI-powered search quickly gains popularity among consumers.

The first in the Gemini 3.5 series, Flash is now the default model for the Gemini app and AI Mode in Search globally, Google said at its annual I/O conference yesterday (19 May).

Gemini 3.5 Flash outperforms Gemini 3.1 Pro on coding and agentic benchmarks, while hitting speeds four-times faster than other frontier models, the company said.

The newest in the Flash series makes significant leaps on agentic and multimodal benchmarks set by the likes of Claude Sonnet 4.6, Claude Opus 4.7 and GPT-5.5. It outperforms others in financial analysis, while reaching just under GPT-5.5’s achievements in agentic computer use.
