Today at Google I/O, Google released Gemini 3.5 Flash. This one skipped the -preview modifier and went straight to general availability, and Google appear to be using it for a whole lot of their key products: 3.5 Flash is available today to billions of people globally:

1. For everyone via the Gemini app and AI Mode in Google Search
   
2. For developers in our agent-first development platform Google Antigravity and Gemini API in Google AI Studio and Android Studio
   
3. For enterprises in Gemini Enterprise Agent Platform and Gemini Enterprise.
   

As usual with Gemini, the most interesting details are tucked away in the What’s new in Gemini 3.5 Flash developer documentation. It mostly has the same set of platform features as the previous Gemini 3.x series, albeit with no computer use. The model ID is gemini-3.5-flash. The knowledge cut-off is January 2025, and it supports 1,048,576 input tokens and 65,536 maximum output tokens.

Full analysis : Gemini 3.5 Flash costs $1.50 per 1M input tokens and $9 per 1M output tokens, 3x the price of Gemini 3 Flash Preview and 6x the price of Gemini 3.1 Flash-Lite.
