Gemini 3.5 Flash - access through LLMTR
Built for production apps that need 1M context, a 65K output ceiling, tool use, PDFs, and media inputs without moving to a heavier Pro tier. It is the stable Flash path for teams migrating from Gemini 3 Flash Preview while keeping a strong balance of speed, quality, and cost.
