- OpenRouter data shows users spent more on OpenAI's models than on Anthropic's during the week of September 7, marking the first weekly crossover in more than 2.5 years.
- The last time OpenAI models outpaced Anthropic models in OpenRouter weekly spend was the week of February 26, 2024, per the platform's own post.
Why it matters: The reversal ends a 2.5-year streak in which Anthropic models led OpenRouter's weekly spend rankings, suggesting a meaningful shift in developer demand on one of the largest third-party AI API aggregators at a moment when both companies are actively competing for enterprise share.
