I think some model providers are implementing "eyes glaze over" where if you ask a boring simple question they route it to a cheap model but charge you for an expensive model, so consumers may want a proof of work certificate to know they're getting what they pay for.

I think a consumer facing system would be fantastic, but from how they're framing it in the article, it's all about internal company monitoring, with some fearmongering around LLM observability.
