Gemini 3.5 Flash is Google's fast multimodal model for people who wanted strong coding and agent work at a Flash-tier price, and it is now superseded. Google announced it on 19 May 2026 and called it its strongest agentic and coding model yet, citing its own score of 76.2% on Terminal-Bench 2.1. OpenRouter lists a context of 1,048,576 tokens, text, image, video, audio and file input with text output, and a price of $1.50 per million input tokens and $9 per million output tokens on its cheapest route as listed on 5 November 2026. Google's own pricing page no longer has a 3.5 Flash row, so we could not cross-check the price with the maker. Google's deprecations page says the model is no longer available in AI Studio, though the endpoint is not shutting down: requests to gemini-3.5-flash are routed to gemini-3.6-flash. Figures come from Google's launch post, its deprecations page and the OpenRouter model list. We have not run it ourselves. We would not start a new project on it. Test Gemini 3.6 Flash first, and keep this entry to read older results and prices.
