OpenAI Models Top Anthropic on OpenRouter for First Time in Years

Users on OpenRouter spent more on OpenAI’s models than on Anthropic’s during the week of September 7.

It is the first time this has happened since the week of February 26, 2024, more than two and a half years.

Developers point to recent price cuts on OpenAI endpoints, changes in default routing, and cost differences across task types as possible reasons for the shift.
