According to CoinMeta, OpenAI has overtaken Anthropic after a gap of 2 and a half years, with the Astra model taking first place in user spending last week. According to the latest data from OpenRouter, users spent more on the OpenAI model last week than on Anthropic, marking the first time since February 2024 that Anthropic's leading position has been broken. The spending on the Astra model accounted for about 19% of the combined spending on OpenAI and Anthropic, surpassing Opus by 16%, making it the most profitable model last week. The comeback of OpenAI began long ago, with some users continuing to use it even after significant price reductions on Terra and Luna. After the launch of Astra, the spending share of OpenAI finally exceeded 50%. However, this only represents the relative spending on OpenAI and Anthropic within OpenRouter and cannot be directly equated with the total revenue of the entire API market or the two companies.
