> It was not until the last year or so that Anthropic started punching above their weight.

Anthropic's stuff been useful for the last two years I'd say, especially in the beginning of Claude Code, but as soon as the Codex TUI was available, I was daily-driving both of them, literally executing the same prompts for each of them and comparing the final results, and Codex simply writes better code in 9/10 cases (but still not always).

Claude Code has only been around for a year and change. At least for our internal tests 2 years ago Anthropic models started to at least become semi-useful but they still were not great, they struggled with structured output. Prior to that their alignment strategy made the products highly unhelpful in an API context. The past 6 months to a year is where Anthropic has really shined, they have model parity and sometimes taking the lead and more importantly their product offering on the consumer side has crushed it.
