Several comments in this thread have used Anthropic's lower pricing as a criticism, but it's probably moot: a month from now Anthropic will release its own $200 model.

Do you happen to have comparisons available for o1-pro or even o1 (non-preview) that you could share since you seems to have tried them all?
From an API standpoint, it seems like enterprises are currently split between anthropic and ChatGPT and most are willing to use substitutes. For the consumer, ChatGPT is the clear favorite (better branding, better iPhone app)
