GPT-4o (2024-05-13) pricing

On OpenRouter, GPT-4o (2024-05-13) costs $5 per million input tokens and $15 per million output tokens. Counting three tokens read for every token written, its average price is $7.5 per million, more expensive than 92 % of paid models (9.8 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 $0.0175. At 1,000 tasks a day, budget $525 a month. The price calculator redoes this with your own volumes.
