r/opencodeCLI on Reddit: Opencode vs Codex CLI: Same Prompt, Clearer Output — Why?
January 16, 2026 -

Hi everyone! I came across Opencode and decided to try it out—was curious. I chose Codex (I have a subscription). I was genuinely surprised by how easy it was to communicate in planning mode with gpt-5.2-low: discussing tasks, planning, and clarifying details felt much smoother. Before, using the extension or the CLI was pretty tough—the conversation felt “dry.” But now it feels like I’m chatting with Claude or Gemini. I entered the exact same command—the answers are essentially the same, but Opencode explains it much more clearly. Could someone tell me what the secret is?

edit#1:
Second day testing the opencode + gpt-5.2-medium setup, and the difference is huge. With Codex CLI and the extension, it was hard for me to properly discuss tasks and plan — the conversation felt dry. Here, I can spend the whole day calmly talking things through and breaking plans down step by step. It genuinely feels like working with Opus, and sometimes even better. I’m using it specifically for planning and discussion, not for writing code. I don’t fully understand how opencode achieves this effect — it doesn’t seem like something you can get just by tweaking rules. With Codex CLI, it felt like talking to a robot; now it feels like talking to a genuinely understanding person.

February 25, 2026 -

switched to ChatGPT Pro not too long ago and i genuinely love codex - simple tool, does what it needs to do, no fluff

but opencode is on another level as a harness. subagents, grep tools, proper file navigation - it's a much more serious setup for real engineering work

and the fact that you're letting us use it freely with the same limits as codex is huge. props for not gatekeeping it unlike, well, you know who

appreciate it OpenAI, this is how you treat your users
