- Retired
Summary
Gemini 3.1 Flash-Lite is on Google's deprecation list, with 7 May 2027 as the earliest date on which it can be shut down and Gemini 3.5 Flash-Lite named as its replacement. Until then it runs at $0.25 per million input tokens and $1.5 per million output tokens with a 1,048,576-token context window.
Google released Gemini 3.1 Flash-Lite on 7 May 2026 and lists 7 May 2027 against it on the deprecation page. Google states that the dates in that table are the earliest possible retirement dates rather than fixed shutdowns, and the model page still shows the model as stable. It is positioned for high-volume agentic workflows, simple data extraction and applications where latency and cost are the primary constraints.
It takes text, image, video, audio and PDF input and returns text, with caching, code execution, file search, function calling, Maps and search grounding, structured outputs, thinking, URL context, the Batch API and flex and priority inference. The output limit is 65,536 tokens and the Live API is not supported.
The replacement costs more: Gemini 3.5 Flash-Lite is $0.3 / $2.5 against $0.25 / $1.5 here, so budget for roughly a 20 percent higher input rate and a 67 percent higher output rate after the migration.
