Oh nice, so Claude/OpenAI isn't as important as (Claude)Code/Codex/OpenCode these days? How is opencode in comparison, the idea of zen does seem quite nice (a lot of flexibility to experiment with different models), though it does seem like a bit more config and work upfront than CC or codex
I'd say OpenCode > Codex > Claude Code in terms of the TUI interface UX. OpenCode feels a lot nicer to use. I haven't noticed a code quality difference, only a difference in the UX
I'm not sure about Zen, but OpenAI seems to be giving me $20 / week worth of tokens within the $20/month
Also for absolutely free models, MiniMax M2.1 has been impressive and useful to me (free through OpenCode). Don't judge the state of the art through the lens of that, though
