@TotteLofstrom I'm using Codex 5.3 and Composer 2.5 as well. Haven't really given GPT 5.5 a fair chance but I feel Opus in general is better at abstract reasoning, architecture, planning while Codex 5.3 is a great coder. Will give GPT 5.5 a try.
@jonatanpallesen Thanks for the source. Interesting that virtually every demographic is increasing their contribution over time. Like 5k per year. Extrapolating, the pakis are net positive in 9 years and somalis in 30 (!!)
