GitHub Copilot Pro vs ChatGPT Plus for Coding (2026)
GitHub Copilot Pro vs ChatGPT Plus for coding in 2026: price, premium requests vs Codex limits, models, IDE support, and which one a developer should keep.

Copilot Pro prices, AI credits and billing rules checked Oct 31, 2026 in GitHub’s plans docs and individual billing docs; Copilot models from GitHub’s supported models docs (Oct 24, 2026). ChatGPT Plus from OpenAI’s Plus help page (Oct 25, 2026), chatgpt.com/pricing (Oct 29, 2026) and Codex pricing (Oct 28, 2026). Every source is listed at the bottom. No affiliate links on this page (how we work).
GitHub Copilot Pro vs ChatGPT Plus, short version: Copilot Pro is $10 a month and lives inside your editor, with unlimited code completions and 1,500 AI credits for chat and agents. ChatGPT Plus is $20 a month and gets you Codex, OpenAI’s coding agent, on the web, in the CLI, in an IDE extension and on iOS, plus all of ChatGPT.
They’re not really the same product. Copilot Pro is the pair programmer that finishes your line before you’ve thought of it. Codex on Plus is the contractor you hand a ticket to. If you write code all day in an IDE, Copilot Pro is the cheaper, tighter fit. If you’d rather describe a task and review a diff, Plus does more per dollar for that job.
Verdict by situation
- You mostly want autocomplete and quick chat in the IDE: Copilot Pro. Completions don’t touch your credits and are unlimited on paid plans.
- You want an agent that takes whole tasks: ChatGPT Plus. Codex runs locally and in the cloud, and OpenAI publishes per-five-hour message estimates for every model.
- You want OpenAI’s bigger models for code: Plus. GPT-6.1 Sol and GPT-6 Astra are on Plus but not on Copilot Pro (they start at Pro+).
- You want Claude or Gemini in your editor for $10: Copilot Pro. It includes Claude Sonnet 5.5 and Gemini 3.8 Flash; Plus is OpenAI models only.
- You do both every day: $30 a month for both is a reasonable stack. More on that below.

Price and limits table
Verified dates in the caption below.
| Plan | Monthly | Yearly | Coding limit |
|---|---|---|---|
| Copilot Pro | $10 | Not offered | 1,500 credits/mo |
| ChatGPT Plus | $20 | Not offered | Per 5h + weekly |
Copilot: plans docs, verified Oct 31, 2026; annual Pro exists only as a legacy plan for existing subscribers. ChatGPT Plus: “$20/month (billed monthly)” per OpenAI help (Oct 25, 2026), monthly plans only per chatgpt.com/pricing (Oct 29, 2026). USD.
Neither one gives you a yearly discount if you’re buying as of Oct 31, 2026, so there’s no “lock in a cheap year” move on either side.
Copilot Pro’s credits vs Codex limits on Plus
These are two very different meters, and only one of them tells you a number you can plan around.
Copilot Pro gets 1,000 base credits plus a 500-credit flex allotment, so 1,500 GitHub AI Credits a month, where 1 credit is $0.01 (GitHub docs, Oct 31, 2026). Chat, agent mode, the Copilot CLI, the cloud agent and Spaces spend credits at per-token prices by model. Code completions and next edit suggestions don’t spend anything. The allowance resets “at 00:00:00 UTC on the first day of each calendar month,” whatever your billing date, and unused credits are forfeited.
If you searched for “premium requests”: that was the old meter, replaced on June 1, 2026. It still applies only to legacy annual plans. Details in GitHub Copilot premium requests explained.
Codex on ChatGPT Plus has no monthly bucket. OpenAI publishes estimated local messages per five hours on Plus (verified Oct 28, 2026):
| Model | Per 5 hours |
|---|---|
| GPT-6 Luna | 350–3,000 |
| GPT-6.1 Terra | 35–285 |
| GPT-6.1 Sol | 15–160 |
| GPT-6 Sol | 15–150 |
| GPT-6 Astra | 5–45 |
OpenAI adds that “These estimates are not fixed message limits” and “Weekly limits may also apply,” and it doesn’t publish the weekly size. Local and cloud tasks share the allowance. Full detail on Codex usage limits.
When you run out: Copilot Pro lets you upgrade (you pay only the price difference), set a dollar budget (“a $10 budget covers 1,000 AI credits”), or wait for the 1st. Codex on Plus lets you “Flexibly extend usage with ChatGPT credits,” but OpenAI doesn’t publish the credit price on Plus. So Copilot’s overage is priced and Codex’s isn’t. That’s frustrating for anyone trying to budget, and it’s a choice OpenAI keeps making.
Honest take: Copilot’s meter is a fuel gauge, Codex’s is a weather forecast. A five-hour window that refills is great for bursty work. A monthly pool is better if you code in long, even stretches and want to know exactly where you stand on the 20th.
Models you get on each
Copilot from GitHub’s supported models docs (Oct 24, 2026) and the GPT-6.1 Terra changelog (Oct 28, 2026). Plus from chatgpt.com/pricing (Oct 29, 2026) and Codex pricing (Oct 28, 2026).
Copilot Pro includes: Claude Haiku 4.5 and 5.5, Claude Sonnet 5 and 5.5, Gemini 3.8 Flash, GPT-5.3-Codex, GPT-5.6 Luna and Terra, GPT-6 Luna, GPT-6.1 Terra, Grok 4.5, 4.6 and 4.7, Kimi K3 and MAI-Code-1.1-Flash.
Not on Copilot Pro (Pro+ and up): Claude Opus and Fable, Gemini 4 Argon, GPT-6 Astra, GPT-6 Sol, GPT-6.1 Sol and GPT-5.6 Sol.
ChatGPT Plus includes: GPT-6.1 Sol, GPT-6 Astra, GPT-6 Sol, GPT-6 Luna and GPT-5.6 Terra in ChatGPT, and GPT-6.1 Terra in ChatGPT Work and Codex.
So the split is weird and worth spelling out. Copilot Pro is the multi-vendor buffet with the top shelf locked. Plus is single-vendor, but it gives you OpenAI’s top shelf. If GPT-6.1 Sol is what you want for hard problems, Copilot makes you pay $39 for Pro+, and Plus gives it to you at $20.
Model availability changes often on both sides, so check before you buy.
Where each works
Copilot Pro: GitHub lists Visual Studio Code, Visual Studio, JetBrains IDEs, Xcode, Vim, Neovim, Zed and Eclipse, plus “the terminal/CLI, through the GitHub Copilot desktop app, on the web, on mobile, in Slack, and in Teams” (Copilot plans page, Oct 31, 2026). All plans include the Copilot CLI and the Copilot app.
Codex on Plus: “Codex on the web, in the CLI, in the IDE extension, and on iOS,” plus cloud integrations like automatic code review and Slack (Codex pricing, Oct 26, 2026). OpenAI’s IDE page lists VS Code, Cursor, Windsurf, VS Code Insiders, Xcode and JetBrains IDEs (Codex IDE docs, Oct 26, 2026). And Plus subscribers can let some third-party tools draw on their allowance through Sign in with ChatGPT (OpenAI help, Oct 25, 2026).
Editor coverage is close. The difference is posture: Copilot is designed to sit beside your cursor. Codex is designed to go do something and knock when it’s done. Walter White said “I am the one who knocks,” and in fairness to Codex, at least it knocks with a pull request.
Microsoft 365 Copilot is a different product for Office apps and isn’t covered here.
Should you pay for both?
$30 a month total. Here’s how I’d think about it.
Copilot Pro’s unlimited completions are the part Codex on Plus doesn’t cover on paper: OpenAI’s Plus and Codex pricing pages describe an agent, a CLI, an IDE extension and cloud tasks, and say nothing about unmetered inline suggestions as you type. Meanwhile, Codex’s agent loop on GPT-6.1 Sol is the thing Copilot Pro can’t give you at $10. They overlap on chat, and that’s the bit you’d be double-paying for.
If you’d use Plus for non-coding stuff anyway (writing, research, images), both makes sense. If you’d buy Plus only for Codex, try Copilot Pro first and lean on its agent mode with cheaper models. If you blow through 1,500 credits in a week, that’s your answer.
One warning from the Silicon Valley school of agent management: Gilfoyle’s Son of Anton “fixed” bugs by deleting the code. Whatever agent you pick, review the diff before you merge.
Here’s what I’d do
I haven’t run a month on either plan; this is OpenAI’s and GitHub’s docs, side by side.
One subscription, mostly IDE work: Copilot Pro at $10. Turn off training on your data in Copilot settings (GitHub says it may train on individual subscribers’ interaction data unless you opt out).
One subscription, mostly “go build this”: ChatGPT Plus at $20, using Codex in the CLI or the IDE extension, with GPT-6.1 Terra as the everyday model, since OpenAI’s own estimates show more messages per five hours than Sol.
Both: fine at $30, as long as you use completions from one and the agent from the other. Paying twice for chat is the bit to avoid.
