Maybe, but that classification by itself doesn't mean anything. Gold is a commodity, but having it is still very desirable and valuable.

Even if all LLMs were open source and publicly available, the GPUs to run them, technical know how to maintain the entire system, fine tuning, the APIs and app ecosystem around them etc. would still give the top players a massive edge.

Of course realizing that a resource is a commodity means something. It means you can form better predictions of where the market is heading, as it evolves and settles. For example, people are starting to realize that these LLMs are converging on fungible. That can be communicated by the "commodity" classification.
