Google launches Gemini 3 Flash as the default model in the Gemini app
Gemini 3 Flash pairs Gemini 3 reasoning with Flash speed, replacing 2.5 Flash as the default in the Gemini app and in AI Mode on Search.
Google has announced Gemini 3 Flash and placed this model in the default position in the Gemini app, while also replacing Gemini 2.5 Flash in AI Mode on the Search tool. The default change takes place on two surfaces with large user bases, indicating that Google treats this as the standard configuration for mainstream tasks.
The model’s main point is combining the reasoning capability belonging to the Gemini 3 generation with the processing speed characteristic of the Flash line. Published pricing stands at 0.50 USD per million input tokens and 3 USD per million output tokens, placing the product in the segment balancing quality and operating cost.
For enterprises, a Flash model with better reasoning capability opens the possibility of using AI for high-volume tasks such as request classification, document summarisation or answering internal queries, which previously required weighing accuracy against cost.
What needs noting is that the price above is calculated per token, so actual cost depends on context length and call volume. The model becoming the default also means the behaviour of these surfaces changes without users actively choosing it, so output results and regression tests should be reassessed.
