At what point does this become false advertising, or even fraud? Imagine paying AWS for a high-performance server, but 5% of customers who order one quietly get a slower, cheaper server and still pay the full price. That's a serious claim and makes me skeptical Anthropic is doing something like that without more evidence.
Actually, as a person who rented a dedicated server two (not from aws) this exact thing happens quite often.
For example a provider quietly underclocks your cpu or puts it is an energy saving plan hoping you won't notice.
