Gemini 4 Flash leaks: codenamed "Hydrogen" - Gemini 4 Flash is in internal testing under the codename Hydrogen. - It maybe also routing in Antigravity. There's a model ID, gemini-3.8-flash-router, which can be related to Gemini 4 Flash. - I am expecting Gemini 4 Flash to be fast and efficient and carrying essence of Argon. - It can launch this week or next week, with Google employee teasing something that can be flash model.
