Where exactly are they behind?

I'm following this very closly and i'm stunned. Any infos on why you think they are behind antrophic in years?

I do see less quality from reasoning at chatgpt compared to Gemini but otherwise i'm not seeing a year or years gap.

They’re about even in general, but for me OpenAI is slightly or significantly ahead in the areas I care about the most. E.g. claude code is a backend slop cannon if you don’t tell codex/gemini to review the outputs.

Anthropic is _unquestionably_ ahead product wise because of their agentic coding tools, but they are not _years_ ahead. In particular, their advantage is in the harness, which is not hard to replicate!
