Author of the article here. Yes, sorry for this. I think I rushed to post that and did not expected to be read by so many people. I used Codex TUI on MacOS using `gpt-5.6-sol xhigh` vs Claude Code TUI on MacOS using `opus-5 xhigh`. Of course it was a mixed work with subagents being Sonnet 5 in case of Claude Code and Terra 5.6 and Luna 5.6 in case of Codex.
