TL;DR
Elon Musk said on Nov. 1 that the cost of serving xAI’s Grok Bot was “unsustainably high relative to revenue,” without giving figures or announcing a specific limit change. OpenAI has also tightened rules on sharing paid subscriptions and plans to combine ChatGPT and Codex allowances in December, while raising some Pro usage allowances. The developments point to more metering under flat monthly fees, not confirmation that those fees are ending.
Elon Musk said on Nov. 1 that the cost of serving xAI’s Grok Bot was “unsustainably high relative to revenue,” while OpenAI set new restrictions on paid-account sharing and announced a shared usage allowance for ChatGPT and Codex starting in December. The moves show providers putting tighter boundaries around heavy AI use, but neither announcement confirms that monthly subscription prices are ending or that a specific new cap has been imposed.
Musk’s statement came in reply to an X user asking for a Grok Bot reset after users reported running out of usage quickly. At 20:34 UTC on Nov. 1, Musk wrote: “The cost of serving Grok Bot was unsustainably high relative to revenue.” He gave no cost, revenue or margin figures and did not say whether xAI had changed the usage pool, planned a reset or would adjust prices. His comment referred to Grok Bot, xAI’s agent, not Grok chat generally.
OpenAI’s help-center rules say the company limits how many paid accounts can be used on one device and how many subscriptions can be purchased with one payment card or device. The limits cover Go, Plus and Pro plans, but OpenAI does not publish a numerical threshold in the source material. From December, OpenAI says Plus, Pro and Business users will draw from one shared allowance for ChatGPT and Codex, measured in tokens. The company says unlimited Instant chats remain outside that allowance.
The changes do not all reduce access. On Oct. 29, OpenAI said it would double the Work and Codex allowance on its Pro 100 and Pro 500 plans and cancel a planned reduction on Pro 200. Those adjustments, alongside the new account rules and shared meter, show a more differentiated system: some customers receive more allowance, while use across products is being tracked together.

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.

Why AI Usage Is Being Metered
For customers, a flat monthly fee may no longer tell the whole story of how much they can use a service. Agent tasks can run through multiple steps and consume more computing resources than a short chat reply. xAI says Grok Bot usage is measured by agent steps and tokens, and that consumption depends on the task and the effort it requires. A weekly pool can consequently run down at different rates for different users.
OpenAI’s published rate card also illustrates why workloads may carry different costs: the source reports that its most capable model consumes allowance per output token at about 100 times the rate of its cheapest model. That figure concerns relative token use on the cited rate card, not a general estimate of a customer’s bill. For users, the practical point is to check the plan’s usage page and allowance before paying for an upgrade, reset or extra credits. Businesses may need to budget for a seat fee plus metered consumption and request usage terms from vendors in writing.
These policies do not prove that providers are abandoning subscriptions. They indicate that a fixed price can coexist with limits, shared pools and different rates for different kinds of work. The distinction matters when comparing plans: “unlimited” access to a particular chat mode does not necessarily mean unlimited use of agents, advanced models or tools.

OpenAI launched a $200-a-month ChatGPT Pro plan in December 2024, describing access to its best models as unlimited. In January 2025, chief executive Sam Altman wrote on X that the company was losing money on Pro subscriptions because customers used them more than expected. That earlier remark is relevant to today’s debate, but it does not establish the current economics of any plan.
xAI launched its X Subscription on Oct. 12, 2026. According to the pricing information cited in the source, Grok Bot is included in Premium at $30 a month, Super at $100 and Ultra at $200, and is not included in Free or Plus. Its use draws from a shared weekly pool that also covers Grok chat and xAI models in the coding tool Cursor. These terms describe the cited plans and may change.
OpenAI’s late-October allowance changes and its December pooling plan arrived in the same period as Musk’s post. Together, they provide a reason to examine how subscriptions define usage. They are not, by themselves, evidence of a coordinated industry-wide decision or a universal shift to pay-per-use.
“The cost of serving Grok Bot was unsustainably high relative to revenue.”

Limits and Costs Still Unpublished
Musk did not say what xAI changed, whether the reported fast usage reflects a revised pool or a temporary issue, or whether a reset, price change or new cap is coming. His use of the past tense does not, on its own, confirm that a change has already taken effect. The source also describes a reported post from Grok’s official account about adjusted allocations and a dashboard fault, but says the post could not be independently located; those details remain reported, not confirmed.
OpenAI has not published the number of subscriptions permitted per card or device in the information provided. The exact mechanics of its combined ChatGPT and Codex allowance—including how it will be displayed and how different tasks will draw it down—also need to be checked against the policy when it takes effect. The source provides no new figures for provider costs, revenue or margins, so claims about the profitability of specific plans cannot be verified from these announcements.
Watch December Usage Rules
The next stated milestone is OpenAI’s planned move to a shared ChatGPT and Codex allowance in December. Customers should look for the full plan terms and usage-meter details as the change approaches. xAI has made no specific follow-up change in the cited statement; any reset, revised weekly pool or price adjustment remains unannounced in the source material.
For now, readers comparing subscriptions can check each provider’s current plan page and account usage display rather than assuming that a fixed monthly price covers every workload without limits. Further official terms or policy updates would clarify how the providers apply these allowances in practice.
Key Questions
Is the AI flat-rate subscription model ending?
The announcements do not confirm that monthly subscriptions are ending. They show that fixed fees can come with usage pools, shared allowances and account restrictions.
Did Musk announce a new Grok Bot limit?
No specific new limit was announced in the cited post. Musk said serving Grok Bot was “unsustainably high relative to revenue,” but gave no figures and did not describe a cap, reset or price change.
What is OpenAI changing in December?
OpenAI says Plus, Pro and Business users will have one shared allowance across ChatGPT and Codex, measured in tokens. The source says unlimited Instant chats remain outside that meter.
Not in the supplied information. OpenAI’s help page describes limits on paid accounts per device and subscriptions per card or device, but does not provide a numerical threshold in the source material.
What should users check before buying an upgrade?
Check the current plan terms and usage page, including which models and tools draw from a pool and whether agent tasks count differently. The reported policies do not establish a single usage rate for every task.
