Quick answer
Same $20, very different receipts. As of Nov 1, 2026, ChatGPT Plus ($20/month, monthly only) gets you Codex in the web app, CLI, IDE extension and iOS, plus cloud tasks and automatic code review. Claude Pro ($20 monthly, or $17/month billed yearly as $200 up front) gets you Claude Code in the terminal and IDEs, with Opus included.
Which codes more? Neither company lets you answer that with a number. OpenAI publishes ranges of local messages per five hours for Plus; Anthropic publishes no message count for Pro at all, only “1x” against its own bigger plans. Anyone telling you one plan gives “3x more coding” is reading tea leaves.
What you can decide on:
- Pick Codex on Plus if you want cloud tasks, code review on pull requests and a Slack integration in the same subscription, or if you already pay for ChatGPT.
- Pick Claude Code on Pro if you want the yearly discount, Opus models in the terminal, and one shared allowance across Claude chat and coding.
- Pick both if you’re hitting limits on one; $40 a month, or $37 with Claude Pro billed yearly.
The two plans are Pawnee and Eagleton from Parks and Rec: neighbors, same zip-code price, and each convinced it’s the nicer town. The difference is in the services, not the sign at the border.

Usage limits and resets
Codex on ChatGPT Plus
OpenAI publishes estimated local messages per five hours on Plus (Codex pricing page, verified Nov 1, 2026):
| Model | Per 5 hours |
|---|---|
| GPT-6 Astra | 5–45 |
| GPT-6.1 Sol | 15–160 |
| GPT-6.1 Terra | 35–285 |
| GPT-6 Sol | 15–150 |
| GPT-6 Luna | 350–3,000 |
The fine print matters more than the table. “These estimates are not fixed message limits; check your usage dashboard for current limits and reset times.” “Cloud tasks may use more of your allowance than local messages.” “Local messages and cloud chats share your plan’s usage allowance. Weekly limits may also apply.” OpenAI doesn’t publish the size of that weekly limit.
When you hit it: check /status in the CLI or the usage dashboard. “Starting a new chat does not reset your usage limits.” If you hit a limit mid-turn, “Codex can continue working on that turn, subject to fair-use limits.” After that, your options are adding ChatGPT credits (“Eligible Plus and Pro users can buy credits without changing plans”), applying a banked reset if you have one, upgrading, or waiting. “OpenAI Support does not reset ChatGPT or Codex usage limits” (Codex help 11369540, verified Nov 1, 2026). Credits last 12 months; OpenAI doesn’t publish a per-credit price (help 12642688, verified Oct 31, 2026).
Full walkthrough: Codex usage limits.
Claude Code on Claude Pro
Anthropic: “Pro and Max plans have a five-hour session limit and a weekly limit.” The five-hour window “starts when you send your first message, and your limit resets in full five hours later.” The weekly limit resets “at a fixed time each week that is assigned to your account” (help 11145838 and 11647753, verified Nov 1, 2026).
What Anthropic doesn’t give you is a number. claude.com/pricing lists Pro as “1x” for both windows and Max as 5x, which tells you the ratio but not the size. There’s one more catch: Anthropic says these limits “are shared across Claude and Claude Code, meaning all activity in both tools counts against the same limits”, so a long chat session in the Claude app eats into your coding time.
When you hit it: wait for the reset (Claude Code can auto-continue when it resets), turn on usage credits billed at standard API rates, or upgrade. Pro also gets a small “wrapping up” allowance to finish an in-progress response, up to once per weekly period (help 11145838, verified Nov 1, 2026). The message-by-message guide is in Claude Code usage limits.
So which has higher limits?
Unknowable from official numbers, and that’s the honest, slightly maddening answer. OpenAI gives ranges that swing by 9x on a single model; Anthropic gives no count. Both say task complexity changes how far the allowance goes. If you’ve used both and one felt roomier, that’s your answer for your codebase, not a law of physics.
Models and tooling differences
Models. The Plus card on OpenAI’s Codex pricing page lists “GPT-6.1 Sol and GPT-6 Luna”, while the limits table on the same page also gives Plus estimates for GPT-6 Astra, GPT-6.1 Terra and GPT-6 Sol (verified Nov 1, 2026). Claude Pro includes Opus, Sonnet and Haiku, with context “Up to 1M, varies by model”; Fable on Pro is “paid with usage credits” (claude.com/pricing, verified Nov 1, 2026).
Where you run it. Codex on Plus covers “the web, in the CLI, in the IDE extension, and on iOS”. The IDE extension supports VS Code, Cursor, Windsurf, VS Code Insiders, Xcode and JetBrains (Codex IDE docs, verified Oct 26, 2026). Claude Code runs in the terminal and in VS Code, Cursor and other forks, and JetBrains, all drawing on the same limits (help 11145838, verified Nov 1, 2026).
Cloud work. This is Codex’s clearest edge at $20. Plus includes “Cloud-based integrations like automatic code review and Slack integration”, and Codex Cloud is available on eligible Plus accounts (Codex help 11369540, verified Nov 1, 2026). Claude Pro’s pricing card lists “Hand off and schedule tasks” as a Pro feature, but it doesn’t spell out a GitHub code-review integration for Claude Code on Pro, so we’re not claiming one.
Billing. Claude Pro’s yearly option saves $36 a year ($240 vs $200). ChatGPT Plus has no annual billing (OpenAI Plus help, verified Oct 25, 2026). Neither subscription includes API usage, and both sell extra usage separately.
Data. OpenAI says Plus and Pro conversations may be used for training unless you turn that off in settings (Codex help 11369540, verified Nov 1, 2026). Check both companies’ privacy controls before pointing either at client code.
Put side by side, these plans are Seinfeld’s “Bizarro Jerry”: same price, same shape, everything mirrored. Codex is generous with surfaces and stingy with clarity on weekly limits; Claude is generous with models and stingy with any number at all.
When to upgrade
If $20 runs out every day, the next steps up (as of Nov 1, 2026):
- Codex: ChatGPT Pro “From $100”, with $100, $200 and $500 tiers, and “Pro plans currently have no five-hour limit” (Codex pricing page).
- Claude: Max at $100 (“5x Pro usage every 5 hours and every week”) or Ultra at $200 (no five-hour limit for verified accounts, “10x Pro usage every week”). Anthropic renamed Max 20x to Ultra: “Existing Max 20x subscribers move to Ultra automatically, with no price change” (Ultra plan, verified Nov 1, 2026). Both are monthly only.
The big-tier fight has its own page: Codex Pro vs Claude Code Max.
Here’s what I’d do
If you already pay for ChatGPT, start with Codex on Plus and use the cloud tasks; it’s the cheapest way to get both chat and an agent that reviews pull requests. If you code mostly in a terminal and want Opus, take Claude Pro on the yearly plan and save $36. If you run out on either within the first month, add the other for $20 before you jump to a $100 tier, because two $20 plans with separate allowances can be cheaper than one big one.
