Summary
Gemini 3.5 Flash is a Gemini 3 Flash release from mid-2026, at $1.5 per million input tokens and $9 per million output tokens. That is twice the input price and 2.4 times the output price of the newer Gemini 3.6, 3.7 and 3.8 Flash models, which offer the same limits and modalities.
Gemini 3.5 Flash is listed with a May 2026 update and is positioned by Google for the agentic era, for multi-step workflows and complex coding iterations. Its pricing is the reason to look closely: at $1.5 / $9 it is the highest-priced Flash model in this dataset, while the three later Flash releases cost $0.75 / $3.75 for the same 1,048,576-token input limit and 65,536-token output limit.
It takes text, image, video, audio and PDF input and returns text, with structured outputs, caching, function calling, code execution, search grounding, URL context, file search, thinking, the Batch API and computer use in preview. The Live API is not supported.
No deprecation has been announced.
