Is there any evidence that it's not?

The fact that Anthropic models are offered at the same API pricing by not just themselves but AWS, Azure and Vertex despite Anthropic taking a major slice on licensing along with the cost an open weight 1T parameter model like K2.6 costs to run on any third-party provider, make it unlikely that API inference cost are subsidized by the labs.

Openrouter? i.e. Even excluding Deep Seek inference for very large open models is way cheaper. Maybe these providers are not very profitable but its highly unlikely that they are losing $4 for every $1 they make since selling inference is their only product...

Yes; they ban various uses of their subscriptions but say you can do whatever if you’re paying for the API without limits

		That's just market segmentation and them trying to maximize revenue it doesen't really say anything about their costs.

		That's not evidence. Very likely though, but the only evidence we get one way or another is when they IPO.

		This story isn't about those subscriptions - enterprise customers like Uber are paying the full API prices.
