We all consider Anthropic an AI company.
But what if it’s a cloud?
Anthropic is growing much faster than the other clouds : 15x last year. GCP’s growth is far behind at 82%. But at current growth rates, Anthropic is closer to GCP’s pace, doubling next year.1

And developers are discovering the value of open models.
OpenRouter offers a useful view into the model market.1 It is not the whole AI economy. But it is close to the API frontier, where developers can switch models quickly, compare price-performance daily, & route each request to the best available option.
Since 2025, open models have grown sharply on OpenRouter. In the latest model-level snapshot, open-weight models generated 69.1% of named open-versus-closed token volume. Closed models produced 30.9%.
