codex-ts fails at markdown / codex-rs doesn't support ChatGPT login?

I was trying out the typescript codex, but found that its output was hideous and borderline unreadable (it wasn't rendering markdown at all), and I found this issue -> https://github.com/openai/codex/issues/1246 <- which says I should be using codex@native instead for nice markdown rendering.

So I fired it up, only to find that it's demanding an API key, and not honoring the typescript codex's auth. Is this expected? I want to use my Plus subscription with codex, but this seems to be a blocker. Was even considering subscribing to Pro if things turned out well.

I really wanted to try GPT-5 in a TUI in a style similar to Claude Code today, but it just doesn't seem like things are up to par yet? Maybe I should check back in a few months. :(
