Gemini 3.1 Flash Lite is Google's cheap, high-volume multimodal model, suited to people who need low-latency work such as classification, extraction and light agent steps at the lowest cost. OpenRouter lists it from 7 May 2026 with a context of 1,048,576 tokens, text, image, video, audio and file input, and text output. Google's pricing page shows the same standard paid rates as OpenRouter: $0.25 per million input tokens for text, image and video, $0.50 for audio, and $1.50 per million output tokens including thinking tokens, as listed on 5 November 2026. The catch is its lifespan. Google's deprecations page gives a shutdown date of 7 May 2027 and names gemini-3.5-flash-lite as the replacement, and the 3.5 Flash-Lite model costs more at $0.30 input and $2.50 output. Google's model page marks the stable id as stable, and a separate preview id has already been shut down. Figures come from Google's pricing, models and deprecations pages and the OpenRouter model list. We have not run it ourselves. We would use it for bulk, low-risk tasks now, and plan the move to its successor before May 2027.
