OpenRouter is running an exclusive extra 50% off on top of Google's own 50% introductory cut, landing Gemini 3.7 Flash at $0.375 per million input and $1.875 per million output tokens, and the discount expires 2026-08-27. Google's standing Vertex price through the end of 2026 is $0.75 and $3.75, doubling to $1.50 and $7.50 on 2027-01-01. r/singularity commenters read the second cut as Google wanting real-world agent traces to train on. Artificial Analysis price/performance charts do not have the OpenRouter discount factored in, so any cost comparison you read this week is understating it.
