I think the biggest advantage of ChatGPT compared to Claude is that there are fewer things outside the model itself, such as KYC, account bans, etc.
OAI and Anthropic both require KYC for models of similar intelligence. They both do account bans if the classifiers fire wrong. You simply hear about it less with OAI because Codex has fewer prosumers.
In terms of bans and KYC they are not meaningfully different.
