GPT-4o (2024-11-20) pricing

On OpenRouter, GPT-4o (2024-11-20) costs $2.5 per million input tokens and $10 per million output tokens. Counting three tokens read for every token written, its average price is $4.375 per million, more expensive than 86 % of paid models (5.7 times the median of $0.76).

A concrete example: a task that sends 2,000 tokens (about 1,500 words) and receives a 500-token answer costs $0.01. At 1,000 tasks a day, budget $300 a month. The price calculator redoes this with your own volumes.

Tokens already sent and cached are billed at $1.25 per million.
