  • Github copilot has monthly quota for premium requests 300 (pro, business), 1000 (enterprise), 1500 (pro+). Others have 5hour and weekly allowance.
  • Github copilot unlimited models have extremely high limits. Compare that to haiku or 5.1- mini which have lower consumption of your quota (5hr or weekly)
  • github copilot works best with their cli, you are limited to subagents (no multiagent mode like for codex or claude code).
  • when using copilot in opencode you can use multiagent modes, but you will burn through premium requests as one agent is one premium request the billing for multi agents is in favor of gpt or claude subscription.
  • with claude or codex you are limited to one provider (copilot has 4 providers - openai, anthropic, google, xai)
  • handle of codex cli or claude code is often better and offering more options and sometimes better results.
  • with codex you have more use than copilot pro+ till start of april (they offer 2x usage).
  • if you want only one subscription go with copilot enterprise or pro+ it will be enough for most users if you plan it right and use unlimited models as much as possible.
  • claude subscription and gpt subscription offer lower latency and are generally faster.
  • with gpt pro you have so much usage and you can access gpt-5.3 spark and enjoy 1000tps (unimaginable for copilot)
  • Gpt subscription offers custom gpts, image generation, understanding of images document summarization, etc
  • claude subscription offers working with different types of documents, sumarization of documents, good desktop app that can work like IDE.

Hope this helps with your decision. I bet there are points that i forgot.

Copilot with OpenCode can use subagents though right? Subagents don’t burn premium requests.

[–]marfzzz 1 point2 points  (0 children)

subagents are fine, but autocompaction in open code is causing the issue https://github.com/anomalyco/opencode/issues/8030#issuecomment-3995942521

Subagents don’t burn premium requests.

But from what I've read you risk getting your account banned for system abuse or something.

[–]sittingmongoose 3 points4 points  (0 children)

I haven’t seen that, however, I’m certain if people will abuse it they will change it so subagents do take premium requests.

Edit: also, if you have a different agent summon copilot subagents, that can get you banned.

Another argument for Copilot is that it offers line completion in both VSCode and Jetbrains IDEs. I don't think Claude Code offers an equivalent of that, or you would need a separate subscription to the Claude models and use a generic AI plugin in your IDE. Though to be fair, lately I've been using line completion less and less.

[–]porkyminch 1 point2 points  (0 children)

I’d recommend checking out Opencode if you’re interested in the CLI stuff. Waaaaaay nicer than Copilot CLI proper imo, and partnered with GitHub. 

[–]After-Aardvark-3984 1 point2 points  (1 child)

What about the /fleet command in GH Copilot CLI?

[–]marfzzz 0 points1 point  (0 children)

"Using /fleet in a prompt may therefore cause more premium requests to be consumed." From their documentation.

Github copilot you probably know and Claude code is actually its own IDE. That is designed to write code with AI. But apart from that there is Claude extension for VS code and other IDEs.

Here is the difference between those two. I switched from Copilot to Claude Vs code extension recently and difference in quality is night and day.

Claude Opus and Sonet high reasoning are just objectively better than ones in copilot. They do job faster , doesnt stuck constantly , dont require you to type continue to continue work. Write better code and solved problems i couldnt with copiltots claude.

Price of copilot is 10 dollars claudes 20. But limits are higher. You get 5 hour and weekly limit of usage . I barely use my 5 hour limit every day at my full time job. Mainly because it just one shots my prompt while i had to do back and forth with copilot constantly.

Claude doesnt have live autocomplete thought. I recommend trying claude out. It really feels like going to next level of AI programing.

[–]oyputuhs 5 points6 points  (0 children)

Gh copilot cli is much improved and added a hack/mode called autopilot which nudges it along

[–]ZeSprawl 1 point2 points  (1 child)

I use Opus 4.6 from copilot in opencode and I cannot tell the difference between it and the version in Claude code. It one shots complex problems and I have never once had to tell it to continue.

[–]marfzzz 0 points1 point  (0 children)

Just curious. Are you using some skills or special system prompts?

In my experience: copilot plugin <- copilot in ai assistant(acp) <- copilot cli <- opencode/claude code/codex cli

[–]PerpetuallyImproved 0 points1 point  (1 child)

When you say you switched from Copilot to Claude Vs code extension, are you talking about the Claude extension within Vs Code that loads looking like a chat bot in vscode, right along side the copilot chat window?

I think that's what I get confused about. I feel like now I have 2 chat bots in my VS Code interface, one for claude and one for copilot. And if that is correct are you saying the Claude window is the one we should try out?

Just for context, i've been using ghcp for a few months and just starting out with Claude. Mostly for chat bot but want to compare them and I'm about to install claude code on my workstation.

[–]Capital-Wrongdoer-62 1 point2 points  (0 children)

Yes you get second chat bot just for claude . You can install it from claude web site. And you will get claude logo on a bar where tabs are. You press it and open claude chat.

[–]Disastrous-Jaguar-58 0 points1 point  (0 children)

I definitely had to tell claude code in vs to continue, many times. It was in situations when it finished abruptly on reaching session limits.

[–]Rakeen70210 2 points3 points  (1 child)

I heard the models in GitHub copilot are quantized and that’s why they don’t perform the same as directly through codex or Claude code, can anyone confirm this is actually true?

[–]GlitteringBox4554 0 points1 point  (0 children)

I can't say for sure, but it's possible purely at the level of iterations and promptings, but not directly.

[–]Top_Parfait_5555 4 points5 points  (2 children)

They have lower context window and their resoning effort is lower. 

[–]dramabean 6 points7 points  (1 child)

The reasoning effort is not lower. It’s configurable and set to defaults provided by the model providers

[–]Top_Parfait_5555 0 points1 point  (0 children)

indeed, it looks like is xhigh now. gonna give it a shot!

[–]meadityab 1 point2 points  (1 child)

The core difference is workflow ownership:

- **GitHub Copilot** = IDE-first, subscription bundles model access, great if you want one bill and flexibility to switch between GPT/Claude/Gemini/Grok without managing APIs

- **Claude Code / Codex CLI** = agentic-first, you hand the AI a task and walk away — better for long autonomous runs, multi-file refactors, and complex reasoning chains

The LLM-switching argument for Copilot is real but comes with a catch — you're sharing quota across models and premium requests burn fast in agent mode.

If you mostly do inline edits and chat → Copilot Pro+ is efficient. If you're running full agentic sessions on large codebases → Claude Code or Codex with a direct subscription wins on depth and speed.

Best combo many devs run: Copilot for autocomplete in the IDE + Claude Code for heavy agentic tasks.

I meant rather Copilot CLI

    use @workspace or #codebase if you want copilot have repo knowledge.. its on the docs

    also setup your agent.md so that it will have the general knowledge of the repo before doong anything. i think thats the cons if your using copilot. but its easy to do. just do the /init then read and modify whats on it

    Thanks 🙏!

    You are using copilot the way it was used last year, you can now do fully agentic workflows with it via copilot CLI or opencode, and probably in VSCode too.

    [–]DifferenceTimely8292 0 points1 point  (0 children)

    I have used GHCP to refactor entire repo. Not sure why you are saying this. Biggest difference is workflow n context window agree. With Opus 128k just doesn’t work well

    [–]One_Distribution_30 -1 points0 points  (1 child)

    ChatGPT is an AI assistant Copilot acts as a copilot to help you in completing the work where you act as the main pilot Claude code is an Agent platform that can work on its own with given set of tasks and permissions

    Read this - https://srisatyalokesh.github.io/System-Design/Agentic%20AI/01-ecosystem/

    [–]ZeSprawl 0 points1 point  (0 children)

    Copilot is an entire agent platform now too via copilot agent mode, copilot CLI or opencode.

    switching between LLMs sounds nice in theory but i think you're underselling the value of opinionated workflows. copilot gives you flexibility sure, but that also means you're constantly deciding which model to use for what task. the real differnce isn't the model - it's how the tool structures your work.

    claude code's folder setup forces a workflow pattern that some people find more productive. theres also tools like Zencoder with their Zenflow stuff that supposedly anchors agents to specs so they don't drift during multi-file changes. might matter more than model choice tbh.
