ChatGPT Pro vs Claude Max: Which $100 Plan Is Worth It?

September 11, 2026 · AI Rabbit Holes

Six months ago I wrote a post about leaving OpenAI, and Claude ran nearly all of my work.

Today my stack is split. ChatGPT Pro vs Claude Max stopped being a question about which model is smarter and became a question about how much of the good model you actually get to use before your plan cuts you off. That is the whole story, and it is why I quietly moved a chunk of work back to OpenAI over the last few weeks.

I'm not deleting anything. I still pay Anthropic, Fable is still the best model I own, and what I said six months ago was true when I said it. But the math changed, so I changed with it.

What Actually Changed at OpenAI

OpenAI has made one of the great comebacks in this space. Four specific things moved, and none of them are the "INSANE update" kind.

GPT-6 Astra Landed on the Pro Plan

Astra reached general availability on September 4. The part most write-ups get wrong: GPT-6 Pro, powered by Astra, sits in the main chat only on the Pro plans, Business Premium and Enterprise. Plus users get Astra inside ChatGPT Work and Codex, not in the standard model picker. So the flagship is genuinely what the $100 buys.

GPT-5.6 Sol Got Good Enough for Content Work

Sol is the model I use most now, and it does the unglamorous jobs well. Drafting, editing, tearing a draft apart, arguing with my own angle.

My read is narrow and it is about one job. For drafting and editing marketing content, Sol got good enough that I stopped reaching for Opus by reflex, and Opus 5 has been slower to follow a brief than it used to be. On the September 5 Authority Hacker podcast, Gael Breton went further than I would, calling GPT-5.6 "a superior model to Opus 5 in every way except design" while arguing Anthropic has no good fallback right now.

ChatGPT Images 2.5 Took Over My Image Work

OpenAI shipped ChatGPT Images 2.5 on September 8, with two API models, Flare and Sunburst. What matters to me is practical: transparent backgrounds, better single-element edits, and holding a subject's face steady across a reference photo. That is most of my thumbnail and diagram workflow, and it replaced what I covered when ChatGPT Images 2.0 shipped.

The Desktop App on a Mac Mini I Can Drive From My Phone

This is the one nobody talks about. OpenAI calls it remote connections. The ChatGPT desktop app runs on a Mac or PC, and you pair your phone to it and drive that session from anywhere.

I run it on a Mac Mini. That machine sits on my desk doing the work while I am somewhere else.

From my phone it looks like this. The green dot and the machine name mean the session is live on that Mac, not running in the cloud.

The catch is real and I want to be honest about it: if that machine sleeps, drops off the network, or the app closes, remote access stops. There is no magic here, just a paired session.

But it is the thing that makes a lot of agent tooling hard to justify for a non-technical marketer. I wrote about why you should avoid OpenClaw and looked at Hermes AI agents for a specific automation job. Both are more setup than this. Remote connections is a QR code and a machine you already own.

The $100 Question

Both companies sell a $100 plan and both sound identical on the surface. They are not, and the difference is how each one meters its best model.

ChatGPT Pro at $100 gives you 5x Plus usage. Claude Max starts at $100 and gives you 5x Pro usage. Same price, same multiplier, apparently the same deal.

It's not the same deal, and the difference is one sentence in Anthropic's own support docs: on Max you can use up to 50% of your weekly usage limits on Fable models. Fable is the model you are paying for. It is metered to half your allowance.

Every figure here is what the two companies published as of September 11, 2026, and this is a fast-moving corner of the market. Check both pricing pages before you buy anything.

There is a second change worth separating out, because it is easy to mix up with the Fable cap. On September 14 Anthropic replaces a temporary 50% boost to Claude Code weekly limits with a permanent 25% increase. That is Claude Code specifically, not your chat usage, and it has nothing to do with the Fable cap above.

Run the arithmetic. If your baseline is 100, the boost put you at 150, and the permanent raise puts you at 125. That is roughly 17% less than what heavy Claude Code users have been living on. Anthropic is correctly calling it a permanent increase over the original baseline. It is also a cut from what you had last week. Both things are true.

One caveat before anyone goes shopping: OpenAI paused new sign-ups to the $200 Pro tier on September 10. Existing subscribers are unaffected and the $100 tier is still open. So the $200-versus-$200 comparison is academic right now if you are not already in.

Which Jobs I Moved and Which Ones Stayed

Forget which model is better and ask which job goes where.

Stayed with Claude Code and Fable: building and running systems. Client site work, the cron publisher, skills, anything touching a repo. This is where my work actually lives and moving it would be moving my whole shop.

Moved to GPT-5.6 Sol: drafting, editing, and red-teaming content. First drafts, tightening, and having a second model attack a piece before it ships. This is high-volume work, and high-volume work is exactly what you don't want metered to half your week.

Moved to ChatGPT Images 2.5: thumbnails, featured images, and the diagrams in posts like this one. Subject preservation is the reason. Getting my own face to stay consistent across a reference photo was the job I kept redoing, and that is the thing 2.5 fixed.

Stayed on OpenRouter: open-source model pulls. DeepSeek, Kimi, GLM when a job is cheap and bulk and does not need a frontier model. That runs under $50 a month and I covered the setup in my post on using OpenRouter inside Claude Code.

I put numbers on that gap a while back. I rebuilt my homepage with Opus and then ran the same task through five open-source models, and the spread was not close. Kimi was the most expensive of them at roughly 30 cents, while GLM came in near two cents. Running it on the frontier models would have cost several times more. Quality was not equal either, which is the point. Frontier models earn their price on work that needs them, and most bulk jobs do not.

Notice the pattern. The expensive, careful, system-level work stayed. The high-volume repeatable work moved to the plan that does not ration it.

Where Claude Still Wins

First, Fable is still the best model I own. Not "was." Is. When I need the highest-quality single output and I am willing to spend limits on it, that is the one I reach for.

Second, Claude Code is still home base. My skills, my systems, my client work all live there. A model being marginally better somewhere else does not beat the system you have already built, which is the whole argument I made for running Claude Code and Codex together.

Third, design. The Authority Hacker guys rate Claude ahead on front-end design, and Gael's own workflow is to run Codex and call Opus specifically when something needs to be designed. Their broader conclusion isn't "drop Claude" either. It is that you have to decide whether the frontier model is worth the money or whether the step below it fits your plan comfortably.

Why the Switch Cost Me an Afternoon

Here is the part I did not expect. Moving this much work between two vendors took an afternoon.

Not because I'm fast. Because almost none of my work lives inside a chat window. It lives in skills, which are plain markdown files that load into Claude Code or Codex. Prompt, rules, examples, guardrails, all in text.

So moving a job from one vendor to another was mostly pointing a different tool at the same files. The system was portable because it was never tied to a model in the first place. That is the same reason I package these as the Claude Code Skills Stack, and it is the single most useful thing I can tell you here.

The model was never the bottleneck. The system is the asset. If a pricing change at one company can strand your entire workflow, you don't have a workflow, you have a subscription.

So here is where I actually stand. I pay for both $100 plans and I reassigned the work between them. I haven't downgraded Max, I'm only considering it. I'm eyeing the $200 ChatGPT tier and haven't moved.

None of that is urgent, because nothing I built is locked to either one. If Anthropic loosens limits next month, the work moves back the same afternoon.

ChatGPT Pro vs Claude Max FAQs

If I can only afford one, which should I buy?

Buy on the job that eats most of your week. If that is writing, editing and images, ChatGPT Pro at $100 gets you more usable output because flagship access is not separately metered. If it is building and running systems inside a repo, Claude Code is worth the cap and nothing else is close.

What is the Claude Fable 50% limit?

On the Max plan, Anthropic's support docs state you can use up to 50% of your weekly usage limits on Fable models at no extra cost. Fable is the flagship, so half your weekly allowance is the ceiling on the model you upgraded for.

What happens to Claude Code limits on September 14?

A temporary 50% increase to Claude Code weekly limits expires and a permanent 25% increase replaces it. Against the original baseline that is a raise. Against what heavy users had over the summer it is about 17% less. This applies to Claude Code, not to chat usage, and it is separate from the Fable 50% cap.

Can I still buy the $200 ChatGPT Pro plan?

Not as a new subscriber as of September 10, when OpenAI paused new sign-ups to that tier. Existing subscribers are unaffected and the $100 Pro plan is still available.

Does this comparison change if I never generate images?

Yes, and it gets closer. Images are a whole category moving to OpenAI, so take that out and you are weighing drafting volume against system work. If you build more than you write, staying on Max alone is defensible.
