## What to use instead

gemini-2.5-flash, named first, is closed to some callers (Google: "we are limiting access to the 2.5 models to users who have actively used them in the past." Projects that already called it keep it; new projects are told to use 3.5 Flash-Lite or 3.8 Flash.). No replacement that holds is named yet. Flash has stayed the name for the fast tier across four generations, so this is the natural target. Google now limits 2.5 Flash to projects that already used it, so a new project should take the current Flash id.
