Anthropic bet on model design, but OpenAI may pull ahead with stronger serving architecture

Anthropic is described as having made a strong bet on model design, but one that was undermined by weaker serving architecture. The post argues that OpenAI has the advantage not just in model quality, but also in the **system for serving models at scale**. In the author’s view, if **GPT-6** delivers as expected, OpenAI could pull even further ahead because the company would combine better models with stronger infrastructure around them.
