Switch to Codex from Claude Code?

[SteamIQ]

Apologize for the rookie question. I have been working with Claude Code CLI forever, MAX 20x plan, hit my weekly limits regularly. Opus 4.6 was a phase change for me. Everything was jamming along and I was very happy.

Since I was using Cursor to manage my files, I would open 3 Ubuntu windows and Create/Dev/Review as my workflow. I'm up to Epic 49 if that gives a sense of scale. Not sure itf thats a lot or not haha.

Anyways on really tough tasks or code reviews I would occasionally utilize Codex in the Cursor agents tab. Sometimes I would run Claude and Codex on the same story and then "compare notes". But Claude did the heavy lifitng because of my subscription. Codex was ala carte.

Does Codex have a standalone CLI interface like Claude Code where I could run them side by side on a similar plan? I haven't been very happy with Opus 4.7 and wondering if the grass is greener on other side of the fence. Is this just install Codex in my folder and run it similar to Claude Code?

Feels like more BMAD users are doing it in Claude Code but I have heard great things about Codex. Anyone made the switch?

Thanks for any guidance.

Codex is like claude code and i am just trying to use codex with bmad, too but i have to admit i'm not sure how it should be handled since the bmad commands don't appear in codex when typing / (after reinstalling bmad).

Claude Code vs Codex：从「单恋」到「多角关系」

我们同时用Claude Code和Codex，踩过一些坑。

我的经验

Claude Code优点：

• 长期记忆(MEMORY.md)让context保持稳定
• 与MCP集成更成熟
• 周订阅模式适合高频用户

Codex优点：

• 按次付费，预算可控
• 某些代码任务更快
• 与OpenAI生态兼容

关键发现

我们最大的token消耗不是LLM调用本身，而是context reinjection。用MEMORY.md后，Claude Code的context成本降了40%。

建议

如果你是BMAD重度用户，可以考虑：

1. 主力用Claude Code（BMAD文档更多）
2. 复杂代码review用Codex对比
3. 设置双引擎预算上限

王家卫式思考

世界上有一种选择叫做Claude vs Codex，它让你在两个AI之间反复横跳，然后发现你需要的是两个。

你们觉得BMAD更适合哪个引擎？

Well I guess I will answer my own question. I bought a $100 Codex plan. You invoke the slash commands by typing $bmad-create-story etc.

It's not as intuitive as Claude and it takes a few mental gymnastics to switch over commands in your head if you are used to Claude.

But I did devise a nice way to use both. I kept Claude as my planner, investiagtion arm and then have it prompt Codex to write code. Codex follows instructions very well, Claude is good at solving problems. Codex is more efficient at token usage too. I could probably downgrade Claude to $100 and keep Codex and have both. Each seems to have a speciality, right now GPT5.5 xhigh/fast winds for me in terms of writing code.

I was finding after the 1MM 4.6 Opus release that my confidence in Opus was failing a bit. Opus 4.7 did not help. Maybe when they ship teh next release they will fix it, until then I will use GPT5.5.
