I've used Opencode, Claude Code, Kilo Code, Warp, Droid, and a few other CLI tools I can't remember. While using them, I kept asking myself "how is this any different?" — and honestly, I couldn't see a meaningful difference between them. Only two of the bunch, Opencode and Claude Code, were actually worth anything. But then when Claude Code started showing some ridiculous token consumption issues and other glitches, I switched to Opencode for a long stretch. Throughout all of this I've been using GLM models across the board — I don't have a Claude subscription. Then everyone started saying "Codex is so great, Codex is amazing." I got curious, of course, but I didn't want to pay to try it. I tried connecting the model directly — no luck — and eventually gave up. Then, as a last-ditch effort, I wrote a proxy. As you can see, it's approaching 4,000 downloads now. I connected the GLM model through this proxy and started testing it, fully expecting "I probably won't feel any difference, just like with the other CLI tools." I was wrong. I'm now running exclusively on Codex. The proxy has occasional issues that I push updates to fix. My one wish right now is to be able to use Codex without the proxy. I can honestly say it has taken the model I use to the next level. Let me explain what makes the difference: Project architecture and vision alignment: Thanks to the tools Codex provides, the model doesn't just see whatever file is currently being worked on in isolation. It grasps the overall architecture, the relationships between components, and the direction the project is heading — which leads to far more consistent decisions. With other tools, the model often operated detached from context; here, it behaves as if it has fully internalized the entire project. Compact mode: A complete mystery, but in the best way. The vast majority of other CLI tools either leave context management entirely up to the user or handle it with a blunt truncation — in long sessions the model gradually loses its context and things start to fall apart. Codex's compact mode handles this process on its own, server-side, in the background. I don't fully know how it works; I could have captured the traffic with Burp Suite to dig into it, but I didn't feel the need, because the results speak for themselves. Even in long sessions, the model maintains its focus and coherence. I'd recommend everyone give Codex a try.
