ChatGPT Pro vs Claude Max (and Ultra): Which $100 or $200 Plan to Buy

ChatGPT Pro vs Claude Max used to be a simple $200 question. It is now two questions, because both plans start at $100 a month, and Anthropic renamed its $200 plan at the end of October. Since 30 October 2026, Claude Max 20x is called Claude Ultra. It drops the five-hour limit for verified accounts, and Anthropic's pricing page now lists it at 10x Pro's weekly usage rather than 20x. Almost every comparison ranking for this search still describes a plan that no longer exists under that name.

This guide compares the plans tier by tier, as of 2 November 2026. It covers the $100 match (Claude Max against ChatGPT Pro 100) and the $200 match (Claude Ultra against ChatGPT Pro 200). It also covers the top models each plan unlocks, what happens at a limit, and the API credits both vendors now bundle. Every price, limit and model row comes from OpenAI's and Anthropic's own pricing and help pages, quoted where it matters. Neither company publishes a message count, so this page does not invent one.

The Key Takeaways

• Same two price points: Claude Max and ChatGPT Pro 100 both cost $100 a month. Claude Ultra and ChatGPT Pro 200 both cost $200. Only OpenAI sells a third tier, Pro 500 at $500.
• The five-hour window is the real split at $100: Claude Max keeps a limit that resets every five hours. OpenAI's Codex pricing docs say "Pro plans currently have no five-hour limit".
• At $200, neither has a five-hour limit: Claude Ultra removed it on 30 October 2026 for verified accounts. Both plans still have weekly limits.
• Claude Ultra is listed at 10x, not 20x: Anthropic's pricing page now says "10x Pro usage every week" for the plan formerly sold as Max 20x.
• Both bundle API credits at the same face value: $100 on the $100 plans and $200 on the $200 plans, but neither vendor lets you spend them on its own chat app or coding agent.

ChatGPT Pro vs Claude Max: The Short Answer

Buy Claude Max or Claude Ultra if most of your heavy use is Claude Code, long documents or Claude's writing. Buy ChatGPT Pro if most of it is Codex, deep research or OpenAI's Pro reasoning mode. The price ladder is identical at $100 and $200. So the decision rests on three things: your coding agent, what the five-hour window costs you, and which top model you reach for.

At $100, ChatGPT Pro 100 is the more forgiving plan for long sessions, because Claude Max still resets every five hours. At $200, that difference disappears. Claude Ultra then wins on context window and on including Anthropic's top model, Claude Fable 5.2. ChatGPT Pro 200 wins on a dedicated reasoning mode and on OpenAI's always-on agent, Dot. Have you not yet hit a limit on a $20 plan in a normal week? Then buy neither. The cheaper single-vendor comparisons in Claude Pro vs Max and ChatGPT Plus vs Pro answer that question first.

What Changed on 30 October: Claude Max 20x Is Now Ultra

Anthropic renamed both Claude Max plans on 30 October 2026. The $100 plan formerly called Max 5x is now just Max. The $200 plan formerly called Max 20x is now Ultra. Prices did not change, and existing subscribers moved over automatically. Anthropic announced it on its official account:

We’re renaming our Max plans:

Max 5x → Max
Max 20x → Ultra

Max is still $100/month, and Ultra is still $200. If you’re a subscriber, there’s nothing you need to do.

We’re also removing the 5-hour limit for verified Ultra accounts, starting today with most existing subscribers. Newer accounts keep a temporary limit until they’re verified, which helps us prevent fraud and abuse. You'll get an email when it's removed.

Weekly limits remain unchanged. View our plans here: http://claude.com/pricing

The change matters for this comparison in two ways. First, Claude Ultra now matches ChatGPT Pro 200 on the five-hour question, which was Claude's biggest disadvantage at $200. Second, the multiplier moved. The old name promised 20 times Pro's usage. The Claude pricing page now lists Ultra at "10x Pro usage every week", and Anthropic's help centre says the same. The Next Web noted that Anthropic's announcement did not mention the change. If you bought Max 20x expecting twenty times Pro, read your weekly meter in Settings, then Usage, before you renew.

ChatGPT Pro vs Claude Max at a Glance

The table below puts the four plans most buyers choose between side by side. Every cell is taken from claude.com/pricing, chatgpt.com/pricing, OpenAI's help centre or the Codex pricing docs, checked on 2 November 2026. "Not published" means the vendor does not state a number.

OpenAI also sells Pro 500 at $500 a month. It has the highest usage of the three Pro tiers and is the only one with Ultrafast, a faster speed mode for GPT-6 Astra and GPT-6.1 Sol. Anthropic has no plan above $200 for individuals.

The $100 Tier: Claude Max vs ChatGPT Pro 100

At $100, ChatGPT Pro 100 gives longer uninterrupted sessions and Claude Max gives a published, predictable multiplier. Anthropic states exactly what Claude Max buys: "5x Pro usage every 5 hours and every week". OpenAI states no multiple for Pro 100 at all. Its help article on Pro tiers ranks them only against each other: "Pro 200 includes more usage than Pro 100."

The five-hour window decides most $100 buyers

Claude Max runs two meters at once: a limit that resets every five hours and a weekly limit across all models. If you burn the five-hour allowance at 11am, you wait until mid-afternoon, even with most of your week left. ChatGPT Pro 100 does not have that first meter in Codex. OpenAI's Codex pricing documentation lists five-hour estimates for Plus and then states, "Pro plans currently have no five-hour limit." Weekly limits "may also apply."

That asymmetry is the single most useful fact at this price. A developer who works in long, unbroken blocks gets more continuous time from Pro 100. A developer who works in bursts across the day barely notices the Claude Max window. Our breakdown of how Claude's session and weekly limits work covers the mechanics of the Claude meters in detail.

What else $100 buys on each side

Claude Max adds Fable to the plan, priority access at high-traffic times, early access to new features and $100 a month in Claude Platform API credits. ChatGPT Pro 100 adds Pro reasoning, Dot, "unlimited and faster image creation", "maximum deep research", "maximum memory and context" and $100 a month in OpenAI API credits. On 29 October 2026 OpenAI also doubled the Work and Codex allowance on Pro 100. OpenAI warned that a larger allowance "does not guarantee twice as many completed tasks."

The $200 Tier: Claude Ultra vs ChatGPT Pro 200

At $200, Claude Ultra and ChatGPT Pro 200 are closer than they have ever been, because both now run without a five-hour limit. The remaining differences are the weekly allowance, the top model and the context window.

Claude Ultra: ten times, not twenty

Claude Ultra gives "10x Pro usage every week" and no five-hour limit for verified accounts, according to Anthropic's pricing page. Verification is automatic and based on account and payment history. Anthropic's Ultra help article says a new account keeps a temporary five-hour limit until it is verified. To check, open Settings, then Usage. If there is no "Current session" bar, the account is verified. Ultra also has a separate weekly limit for Fable, and it doubles the API credit to $200.

The Claude Max plan, by contrast, is 5x every five hours and every week. So the step from Max to Ultra doubles the weekly allowance and removes the five-hour wall. It does not quadruple anything, whatever the old "20x" name suggested.

ChatGPT Pro 200 after the 29 October reversal

ChatGPT Pro 200 keeps the allowance OpenAI had planned to cut. OpenAI's help centre says "The reduction announced in our September 29 email is canceled", and subscribers on the lower allowance had it doubled to match. Pro 200 does not include Ultrafast, which OpenAI reserves for Pro 500. It does keep separate weekly message limits for GPT-6 Pro in Chat, which OpenAI says are "separate from your Work and Codex allowance." OpenAI publishes no number for them.

Which Models Each Plan Unlocks

Claude Max and Ultra unlock Anthropic's whole lineup, including its top model, while ChatGPT Pro unlocks a reasoning mode that ChatGPT Plus cannot reach. That is the one true capability gap on each side.

On Claude, Opus, Sonnet and Haiku are on every paid plan, Pro included. Fable is the exception. Anthropic's help centre says Fable runs on pay-as-you-go usage credits on Pro. On Max and Ultra it is "a standard part of your plan", usable for up to 50% of your weekly limit. The 50% is a ceiling inside the same weekly limit, not extra usage on top. If you are unsure whether you need Fable at all, Claude Fable vs Opus compares the two models directly.

On ChatGPT, Plus already reaches GPT-6 Astra and GPT-6.1 Sol. Pro adds "Pro reasoning powered by GPT-6 Astra" and GPT-5.6 Sol Pro, which OpenAI's pricing page lists for Pro and not for Plus. Pro also lifts the context window from 256K to 400K on reasoning models and from 54K to 128K on GPT Instant.

Claude's context runs larger. Anthropic lists "Up to 1M varies by model" on every paid plan, and its help centre puts Fable 5.1, Opus 5.5, Opus 5, Sonnet 5.5, Sonnet 5 and Haiku 5.5 at 1M tokens in chat. Fable 5 and the Opus 4 models stay at 500K, and other models at 200K. If your work is one very long document or a large codebase in a single session, that difference matters more than any usage multiplier. For model quality rather than plan limits, see Claude vs ChatGPT on the models themselves.

What Happens When You Hit the Limit

ChatGPT Pro lets an agent finish the task it is working on, while Claude Max and Ultra stop until a reset unless you have switched on usage credits. Both vendors then let you keep going for extra money.

OpenAI's Codex pricing documentation puts it this way. "If you reach your usage limits during an active turn, the agent will be able to continue working on that turn, subject to fair use limits." After that, Plus and Pro subscribers can buy credits. Credits cover Codex, ChatGPT Work and the Word, Excel and PowerPoint add-ins, but not every ChatGPT model or feature. Our guide to how ChatGPT credits work covers the rates.

Anthropic's equivalent is usage credits. With them enabled, a Claude Max or Ultra plan switches "to consumption-based pricing at standard API rates" once any included limit runs out. Billing continues until you reach a monthly spend limit you set. Turn usage credits on before a deadline day, not during one. Claude Code shares the same pool: Anthropic's help centre says limits are "shared across Claude and Claude Code, meaning all activity in both tools counts against the same limits."

API Credits: Same Dollar Amounts, Different Rules

Both vendors now include monthly API credits worth the plan's own price at $100 and $200. Neither set of credits extends your chat or coding-agent allowance.

Claude Max and Ultra include $100 and $200 a month for the Claude Platform, claimed into one Console organization after seven days on the plan. Anthropic says the credits "don't cover interactive Claude Code sessions or extra usage after you hit your plan's limits." Claude Pro gets none.

ChatGPT Pro 100, 200 and 500 include $100, $200 and $500 a month, claimed into one linked API organization after seven days. OpenAI says the grant "does not increase your ChatGPT or signed-in Codex usage allowance." Monthly grants expire at the end of the billing cycle and do not roll over. ChatGPT Plus gets none.

So the credits are a bonus for people who build their own apps or agents. If you never call an API, value both $200 plans at $200 of app usage, not $400.

Claude Max vs ChatGPT Pro for Coding, Research and Writing

Claude wins for developers who live in Claude Code. ChatGPT wins for researchers who live in deep research. Writing is a model preference, not a plan feature.

For coding

Pick the plan that matches the agent you already run. Claude Code is included on every paid Claude plan and draws from the plan's limits. Codex is included on ChatGPT Plus and Pro, and on Pro it shares one Work and Codex allowance with ChatGPT Work. If you have no preference yet, ChatGPT Pro 100 is the safer $100 buy for long sessions, because of the missing five-hour window. At $200 the two are even on that point, so the agent decides. For per-plan costs of the terminal agent alone, see what Claude Code costs on each plan.

For research and analysis

ChatGPT Pro has the stronger case. OpenAI lists "maximum deep research" and Pro reasoning as Pro features, and Dot runs in the background on Pro only. Claude Max and Ultra include Anthropic's Research feature. But Claude Pro already has Research, so the $100 or $200 buys more of it rather than a different tool.

For writing and long documents

Claude has the edge on long inputs, with up to 1M tokens of context listed on every paid plan against 400K on ChatGPT Pro. Whether you prefer Claude's or ChatGPT's prose is a test you run yourself on the $20 plans before paying five times more.

Which One Should You Buy?

Start at $100, not $200, on whichever vendor runs your main tool, and let one ordinary month decide the rest. Both vendors sell these tiers monthly only, so you are never locked into a year.

If you are paying for several AI subscriptions already, run the AI subscription audit before adding a $100 one.

The option that avoids picking a side

Most people searching this comparison are not choosing a model. They are choosing which company gets $100 or $200 a month. For everyday chat, you do not have to pick a side. Ask Claude for the long document and GPT for the second opinion, in the same window, without a second bill. Fello AI puts Claude, GPT, Gemini, Grok, DeepSeek, Perplexity, Kimi, GLM and Qwen behind one subscription in a native Mac, iPhone and iPad app. It starts from $11.99 a month in most countries (October 2026 pricing), has a free tier, and holds 4.7 stars across 27,000+ reviews. It does not replace Claude Code or Codex for agent work. It replaces the second chat subscription.

The Verdict

ChatGPT Pro vs Claude Max is now a fair fight at both price points, and the coding agent you already use is the tiebreaker. At $100, ChatGPT Pro 100 is the better buy for long uninterrupted sessions, because Claude Max still resets every five hours. At $200, Claude Ultra has caught up on that point and leads on context and on including Fable, while ChatGPT Pro 200 leads on Pro reasoning and Dot. Ignore any comparison still calling Claude's top plan "Max 20x": the plan is Ultra, the page says 10x weekly, and that is the number to judge it by.
