TL;DR
AI providers are keeping flat monthly plans but adding or clarifying limits on how subscribers use them. OpenAI is combining some ChatGPT and Codex allowances in December and restricting multiple paid accounts tied to one device or card; Elon Musk said Grok Bot’s serving costs were unsustainably high relative to revenue, without providing figures or announcing a specific change.
OpenAI is tightening how some paid AI use is counted, while xAI chief executive Elon Musk said Grok Bot’s serving costs were unsustainably high relative to revenue. The developments, reported between October 29 and November 1, 2026, suggest providers are refining usage limits beneath monthly subscriptions—not announcing an end to flat-rate plans.
On Nov. 1, Musk replied on X to a user asking for a Grok Bot reset after people reported using up their allowance quickly. “The cost of serving Grok Bot was unsustainably high relative to revenue,” he wrote. The post gave no cost, revenue or margin figures and did not say whether xAI had changed limits, prices or reset policies. It referred to Grok Bot, xAI’s agent, rather than Grok chat generally.
OpenAI’s help center says it limits how many paid accounts can be used on a device and how many subscriptions can be bought using one card or device. The rules cover Go, Plus and three Pro plans, but the company has not published the numeric thresholds. OpenAI also says that beginning in December, Plus, Pro and Business plans will share an allowance across ChatGPT and Codex, measured in tokens. Unlimited Instant chats are outside that shared meter, according to the source material.
The changes are not all reductions. OpenAI’s Oct. 29 release notes say Pro 100 and Pro 500 received twice their previous Work and Codex allowance, while a planned reduction for Pro 200 was cancelled. A developer associated with Codex and ChatGPT posted a broader description of doubled limits, but the release notes specify which allowances changed. More allowance and tighter accounting arrived in the same week.

More allowance, more metering: the week the AI flat rate cracked
In four days, OpenAI raised some limits, tightened others and announced one shared meter, and Musk called the cost of serving Grok Bot unsustainably high relative to revenue.

OpenAI gives more on top plans
Pro 100 and Pro 500 get twice their Work and Codex allowance. A planned cut on Pro 200 is cancelled.
Limits per card and per device
ChatGPT may block a new subscription if too many are tied to one card or device. Applies to Go, Plus, Pro 100, 200 and 500. No number published.
One meter from December
Plus, Pro and Business: one token-based allowance across ChatGPT and Codex. Unlimited Instant chats stay outside.
Musk: Grok Bot cost too much
One sentence, past tense. No figures, no new limit, no word on resets or prices.
Paid resets on ChatGPT pull next week’s allowance forward; they do not add usage. Credits are a prepaid balance used after the included allowance.

Subscription Prices Meet Usage Meters
For subscribers, a monthly price alone may not describe how much work a plan can handle. A short chat and a prolonged agent task can consume very different amounts of computing resources, and allowances may be shared across products. Users comparing plans will need to check which tools draw on the same pool, how usage is measured and whether their tasks fall within stated limits.
For companies, the changes make budgeting harder if staff use both chat tools and coding agents under one subscription. The source reports that OpenAI’s rate card assigns very different token costs to models, with its most capable model consuming allowance about 100 times faster per output token than its cheapest. That comparison is specific to the rate card described; it does not establish the cost of every task or provider. Businesses may need written details on included usage and overage terms before committing to plans.
The broader business issue is that flat monthly billing can coexist with metering. Providers can retain a familiar subscription price while setting shared pools, account controls or task-based limits. That may make costs more predictable for some users, but it also means the practical value of a plan depends on the rules behind its headline price.

How the Plans Reached This Point
The source traces the debate to OpenAI’s December 2024 launch of a $200-a-month ChatGPT plan described as offering “unlimited access” to its best models. The following month, chief executive Sam Altman wrote on X that OpenAI was losing money on Pro subscriptions because people used them more than expected. That earlier comment is evidence of a cost concern at the time, not a current accounting of the plan’s finances.
xAI’s current model also combines a subscription with a usage pool. The source says Grok Bot is included in the Premium, Super and Ultra plans, priced at $30, $100 and $200 a month, respectively, and draws from a weekly pool shared with Grok chat and models used in the Cursor coding tool. xAI’s documentation says usage is measured in agent steps and tokens, not simply message counts, and depends on the task’s type and effort.
OpenAI’s October changes likewise cover both access and allowance: account-level restrictions address how subscriptions are used, while the December change combines ChatGPT and Codex usage. These are provider-specific rules; the available material does not establish a single industry-wide policy or a coordinated change among companies.

Limits and Costs Still Unspecified
xAI has not disclosed Grok Bot’s actual costs, revenue or margin, and Musk did not identify what, if anything, changed before his post. He did not confirm a usage-pool reduction, a reset, or a price adjustment. The source says some reports attributed a separate explanation to Grok’s official account, including references to adjusted allocations and a dashboard fault, but its author could not locate the post. That account remains reported rather than independently confirmed here.
OpenAI’s help center describes card and device restrictions without giving the number of subscriptions that trigger them. The source also does not provide the precise size of the December shared allowance or establish how often users will encounter its limits. It is not yet clear how these rules will affect typical subscribers, since usage depends on individual plans and tasks.
These developments do not prove that flat-rate AI subscriptions are ending across the industry. The evidence supports a narrower finding: providers are managing access and consumption more explicitly while continuing to offer monthly plans. The financial effect on providers and customers remains unknown from the published information cited.
The next stated milestone is OpenAI’s plan to begin sharing the relevant Plus, Pro and Business allowance across ChatGPT and Codex in December 2026. Subscribers will be able to assess how the change works once it takes effect and the company’s usage pages show how consumption is tracked. The source provides no further date for updated limits or additional pricing details.
xAI’s next steps are less clear: Musk’s post did not announce a timetable or a specific policy change. Users and companies can monitor provider help pages and plan terms for updated allowance, reset and account-sharing rules. For business buyers, the immediate practical step is to request specific usage and overage terms in writing; individual subscribers can review their usage before paying to upgrade, reset or buy credits.

What changes is OpenAI making to ChatGPT and Codex allowances?
Starting in December, OpenAI says Plus, Pro and Business plans will use one token-measured allowance across ChatGPT and Codex. The source says unlimited Instant chats remain outside that meter.
How many paid accounts can use one device or payment card?
OpenAI’s help center says it limits subscriptions associated with a card or device, but the source material says the company has not published a numeric threshold.
