Our verdict

Check the price before you migrate on version number alone. Gemini 3.6 Flash costs $1.5 / $7.5 per M tokens against $0.3 / $2.5 for Gemini 3 Flash, five times the input and three times the output, for a context window that is effectively unchanged at roughly 1M. What the money buys is a different job: 3.6 is tuned for agentic work, front-end and app generation, and it adds video input. If you run realtime voice, OCR or budget RAG pipelines, Gemini 3 Flash remains the correct and much cheaper choice. Move to 3.6 only for agentic or code-generation workloads.
