I'm not saying Open AI pricing is entirely unrelated to size/cost. I'm saying why are we assuming that OpenAI is serving say OAI-Opus but at half the price of Anthropic when they could just be serving GPT-5.x which is genuinely near half the cost of Opus at scale.

The official API output tokens cost of GLM-5.2 is like a third of Gemini-3.1-Pro. The model is Open weights so we know it's not just a ploy to grab users at the cost of bleeding money. You can actually serve the model profitably at similar prices.

They have near a billion consumer users every week. Compute efficiency at scale would be at the forefront of any training effort. It makes a lot more sense to me that they have more compute efficient models (even with the scaling) than Anthropic rather than just serving Opus/Fable at half the costs Anthropic are incurring.
