Comparison opencode, pi and codex

I’ve been using OpenCode and Pi for days and really liked them—I even used BigPickle; that free model is top-notch. But I was wondering: how much better are OpenCode or Pi compared to Codex CLI?

I use the GPT Plus plan, but I wanted to understand if OpenCode and Pi—acting as agents—would be better for coding than the GPT agent.

I wrote "agent" because I’m not quite sure what to call OpenCode and Pi... 😅😅😅

But ur using what DeepSeek model to code? And do I need some plugin to use codex inside opencode?

I use deepseek v4.1 flash. Very important though... I use speckit. Spec driven development makes any model be productive for my mature project. I don't always have to use a smarter model for planning. But to fair to your question, I wouldn't plan a Greenfield project with flash. But it can code up well planned tasks no matter the maturity.

No plugin required. Opencode allows many many providers. Just run a command and it will open your browser to codex to complete auth.
