For what I use them for, the LLM market has become a two player game, and the players are Anthropic and Google. So I find it quite interesting that OpenAI is still the default assumption of the leader.
ChatGPT dominates the consumer market (though Nano Banana is singlehandedly breathing some life into consumer Gemini).
A small anecdote: when ChatGPT went down a few months ago, a lot of young people (especially students) just waited for it to come back up. They didn't even think about using an alternative.
codex cli with gpt-5.2-codex is so reliably good, it earns the default position in my book. I had cancelled my subscription in early 2024 but started back up recently and have been blown away at how terse, smart, and effective it is. Their CLI harness is top-notch and it manages to be extremely efficient with token usage, so the little plan can go for much of the day. I don’t miss Claude’s rambling or Gemini’s random refactorings.
Interestingly Claude is so far down in traffic it's below things like CharacterAI, it's the best model but it's something like 70% ChatGPT, 10% Gemini and Claude is only 1% or so
What do you use them for?
GPT5.2 Codex is the best coding model right now in benchmarks. I use it exclusively now.
Only in HN and some reddit subs I even see the name claude. In many countries AI=ChatGPT.
