I've been happilly using kimi models via the $10/month opencode-go[1] subscription for a few months now. I also use pi[2], instead of opencode. Their extensions api is nice, though OpenCode's is similar. My personal preference is more minimalism, add extensions when I want them, instead of the kitchen sink approach.

This is entirely for personal use and small projects. I don't have huge needs. I get access to gpt models via my employer for work things. But I'm also using pi with those models.

I use everything except for Anthropic's models in opencode.

I don't use Codex CLI myself, but you can configure it to point to OpenRouter instead. OpenRouter has some instructions for Codex CLI and Claude Code here (though they mention Claude Code is not guaranteed to work!):
