But as the GP points out, open-weight model providers are charging comparable rates and very likely have positive profit margins. That would imply that with API pricing tokens are sold at above cost.

He just told you. Because overwhelming public evidence supports the claim. Especially the pricing of open weight model inference. Why do you allow a prejudice to overshadow evidence?
