Gemini 3.5 Pro

Google · not a catalogue row

• This catalogue, last fetched from OpenRouter on 2026-08-28, has no google/gemini-3.5-pro row. It does not invent a Pro price or an Elo.
• Gemini 3.5 Flash is in this catalogue and has an LMArena score. Whether anything is both better and cheaper is computed on that page, not frozen here.
• The closest Pro-named rows here are Gemini 3.1 Pro Preview and Gemini 2.5 Pro, both of which have an LMArena score in this catalogue. Neither is Gemini 3.5 Pro.
