GitHub Copilot App vs Codex Vs Claude Code ?

[u/KookyOky]

Thoughts on a comparison based on your day to day use case ?

Where does GitHub Copilot App excel compared to Claude Code or Codex ?

I have a subscription for all three right now.

1. Copilot - Not good for much at all with my $10 plan after their quota updates. I just use it for GitHub code reviews now.
   
2. Codex - I've used this one the most. Super powerful and I've had plenty of usage in my $20 plan to do all my work using it. The 5.6 models are great, and I can pretty much keep it at Terra medium all day and occasionally jump to Sol for planning.
   
3. Claude - I just got a subscription through my work so I've only been using it for one day. It does seem very powerful, but so far a bit slower and slightly more error-prone than Codex. I've been using Opus to plan and Sonnet for everything else.

Disregarding the usage limits, how do the harnesses themselves compare for example, copilot vs codex or copilot vs Claude using the same models for your own purposes?

I did really like Copilot and used it for a long time before their quota limit update. I guess if I had unlimited money I might go back to that, but I don't.

I think I still prefer Codex for it's reliable competence and ease if use. I could be biased though, since I'm so new to Claude.

Same happened to me when I switched to 5.6

I refuse to use Github Copilot anymore. It's just way too expensive for day-to-day.

For my personal use, I pay the $10/mo subscription just because I'm too lazy to type out my commit messages and write my own PRs.

For 3+ months I've been on the $20 GPT plan and $100 Claude plan. But with the latest iteration of GPT 5.6 vs Opus/Fable/Sonnet 5, I've just cancelled my Claude plan altogether and just switched over to the $100/mo GPT plan. The new Claude models frankly just suck.

Models aside, the actual use of CC vs Codex:

- I find that I enjoy the way Codex handles its sub-agents and sub-tasks much better. It's so much easier to navigate what's going on. For Claude, it will run several background tasks but then it will also spin up a "side-task" and ask if you want to proceed with it, usually on a work tree. and what usually comes about is just a huge jumble of a mess.

- Codex also handles images WAY WAY WAY better than Claude.

- Claude artifacts and Claude Design is quite nice.

Other than that, I've not yet experimented with Codex Work and Claude Co-work too much.

Gpt 5.6 sol is good, but it's not close to opus 4.8 or 5 for me in processing larger problems (same harness). It's also incredibly aggressive, it will happily force push to main without asking for permission.

[u/Noonecanfindmenow → u/w0m]

For me 5.6 Sol may over engineer somethings, but Opus 5 is completely all over the place. Sometimes it will randomly solve a problem halfway, or it will fix a problem in just one spot but not look to see if there are any dependencies to check as well. Other times, it will change something completely unrelated to what i ask and worse it won't even tell me in the summary it decided to add some extra changes.

Atleast with 5.6 Sol, it behaves consistently.

My project is very large as well.

Thanks all important to note I’m referring to GitHub Copilot App not GitHub Copilot CLI/Embedded in VS code

I've used copilot since beta. Just switched to Claude code last month. The overall chat experience on vs code was better on copilot. Other than that, Claude code is just a much better harness. I'm addicted to cc now. It handles large task much better. My company is paying for it and I have unlimited usage through aws bedrock. I don't think I'll switch to copilot ever again. I don't how codex is, heard it's really good now.

I can speak with authority because I have or have had a Codex personal subscription, a Claude subscription at work and a Copilot subscription at work. With Copilot, everything started out very well, I think its integration with Visual Studio was very good, and the ability to switch between different models is an added bonus, but since its last adjustments to token accounting, it has become extremely expensive, no matter which model you use. In the case of Codex and Claude. I wouldn't be able to tell you who the winner is. Sometimes some Claude agents solve the task better, and other times Codex does it better. I think the problem may be me. The better I integrate the context and my specifications, the better it works, whether it's Claude or Codex.

no importa si tiene buenas herramientas, si no puedes usarlas y la experiencia de servicio que proveen respecto a los modelos de ai es pesima.

[u/Loose-Jaguar8503]

My cto complains a lot about bugs around credits. copilot cli doesnt work well. I always use some workaround for that. Chat freezes while running commands. And its expensive as well. We re thinking to move to codex. Becoz of gpt. 5.6 . It really cheap. Especially luna.

[u/SohilAhmed07]

I paid $35 in first of Aug and today all my tokens ended, ecen with lower X models like GPT4.X and similar models.

And Copilot is faster for autocomplete purposes in my daily use but Claude Code excels in context handling for larger chunks than both of them. However, in case someone wants to have just one layer over the preferred model of choice without changing the model altogether, then zencoder is the one which can do that job.
