As much as I dislike OpenAI’s ongoing shenanigans and disdain for their own customers, I tried to sign up for Claude last week.
Turns out that Anthropic’s signup flow has been silently broken for months for Firefox users: https://old.reddit.com/r/ClaudeAI/comments/1bq06yz/phone_ver.... You get the SMS verification code, and you can enter it, but you get a barely visible “Invalid verification code” error message followed near-instantly by a refresh of the page. I reached out to support, but like many others, heard nothing back.
This barely-disguised contempt for what should likely be their most valuable power-user base suggests to me that a lot of the recent departures from OpenAI are being driven by push instead of pull, and I’m not convinced that Anthropic will remain a competent competitor in the LLM arms race long-term.
