The growth in Codex users is coming at the expense of Claude users. Codex now has over 20 million weekly active users, and at the same time, more and more users are canceling their Claude subscriptions.

In personal conversations, I'm hearing real frustration with Anthropic, and I feel the same way. Opus is incredibly annoyingly verbose and has developed an almost arrogant attitude. Fables' rates make it difficult to use in subscription plans because the rates are used up so quickly. And you won't find a good mid-tier model like Luna or Terra in OpenAI with Sonnet: too expensive, too slow.

Yes, Anthropic is slowly trying to find solutions, such as the concise output mode that was released yesterday. But overall, I'm finding that I simply don't want to use Claude anymore. I'm annoyed and starting to hate it.

Honestly, every single day I have to double-check everything, repeatedly point out errors, and hear statements like "You're right, I overlooked that..." or "You're right, that was wrong." It's so 2024 that I'm shocked Opus is constantly lazy, sloppy, and annoying.

If this continues, Codex will quickly break the 30 million mark, and Anthropic will soon play a subordinate role. How things will look in Business and Enterprise might be a different story.

tl;dr love for codex, dislike for claude. It's sad to see the downfall of Anthropic.
