TL;DR
Elon Musk said on Nov. 1 that serving Grok Bot cost more than its revenue could sustain, but gave no figures or details of a specific limit change. In the same week, OpenAI published paid-account sharing limits and said ChatGPT and Codex will share an allowance from December. The developments point to more metering beneath flat monthly prices, not the end of subscriptions.
Elon Musk said Nov. 1 that the cost of serving xAI’s Grok Bot was “unsustainably high relative to revenue,” while OpenAI published new limits on paid-account sharing and announced that ChatGPT and Codex will use a shared allowance from December. The changes show how AI companies are tightening or restructuring usage beneath monthly subscriptions, though neither Musk’s post nor OpenAI’s announcement means flat-price plans are ending.
Musk made the comment in reply to an X user asking for a Grok Bot usage reset after people reportedly exhausted their usage quickly that week. His response gave no cost, revenue or margin figures, and did not say whether xAI had changed the weekly usage pool, would reset accounts, or planned a price adjustment. The remark referred to Grok Bot, xAI’s task-performing agent, not Grok chat generally.
According to xAI’s pricing information, Grok Bot is included with its Premium, Super and Ultra plans, priced at $30, $100 and $200 per month respectively, and draws from a shared weekly usage pool. xAI’s documentation says usage depends on agent steps, tokens and the work requested, rather than simply the number of messages. Those details help explain why an agent task can consume a different amount of capacity from a short chat reply; they do not establish how much Grok Bot costs xAI to serve.
OpenAI’s changes cut across both access and usage. Its help center says paid ChatGPT accounts are subject to limits on how many can be used on one device and how many subscriptions can be bought with one payment card or device. The policy covers Go, Plus and Pro plans, but the cited help page does not publish a numerical threshold. OpenAI also says Plus, Pro and Business subscribers will draw from one allowance across ChatGPT and Codex beginning in December. The source material says unlimited “Instant” chats remain outside that meter.
Infographic 01 · One week, four moves
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.

Monthly Prices, Measured Usage
For subscribers, a fixed monthly bill does not necessarily buy an unlimited amount of every model or feature. Usage pools and task-based meters can make the practical value of a plan depend on which tools a person uses and how demanding their work is. Before upgrading, users may need to check their account’s usage page and the plan’s specific limits rather than treating “unlimited” as applying to every capability.
For businesses, a subscription seat price may not be enough to forecast spending or capacity when employees use agents that run for longer periods or draw on more expensive models. OpenAI’s changes also mean ChatGPT and Codex usage will be accounted for together for covered plans from December. Companies may want vendors to specify allowances and overage or reset terms in writing. That is a budgeting implication, not evidence that any particular customer’s bill will rise.

From Pro Plans to Agent Pools
The developments follow an earlier warning from OpenAI about the economics of high-use subscriptions. In January 2025, chief executive Sam Altman said the company was losing money on its $200-a-month ChatGPT Pro subscriptions because people used them more than expected. That statement concerned OpenAI’s plan at the time; it does not establish the financial performance of current plans or of xAI’s service.
The source article says OpenAI announced its $200 monthly ChatGPT plan in December 2024 with “unlimited access” to its best models. The more recent details describe a more qualified arrangement: access is tied to plan rules and allowances, with some activity measured separately. On Oct. 29, OpenAI also increased the Work and Codex allowance for Pro 100 and Pro 500, and cancelled a planned reduction for Pro 200, according to its release notes. Those increases happened in the same week as the new sharing rules and December shared meter.
OpenAI’s published rate card, as described in the source material, charges different amounts of allowance for different models; the most capable model uses about 100 times as much allowance per output token as the cheapest. This comparison applies to output-token allowance on that rate card, not to the price or cost of every AI request. Anthropic’s Claude subscriptions also have usage limits, according to the source article, but no specific new Claude policy is identified in the material.
“The cost of serving Grok Bot was unsustainably high relative to revenue.”
— Elon Musk, replying on X on Nov. 1, 2026
Limits and Costs Still Undisclosed
Musk did not disclose Grok Bot’s costs, revenue or margins, or say what changed in response to the costs. His use of “was” prompted some observers to infer that a cost adjustment had already occurred, but that interpretation is not confirmation. The source article also mentions reports of a post from Grok’s official account about adjusted allocations and a dashboard fault, but says the writer could not locate the post; those details remain reported rather than independently confirmed in the material provided.
OpenAI’s account-sharing page, as described in the source, does not state how many paid accounts are permitted on one device or how many subscriptions can be tied to one card or device. The exact mechanics of the December shared allowance—including how usage will be allocated between ChatGPT and Codex—are also not detailed here. It is not clear whether OpenAI or xAI will make further changes to prices, resets or usage pools.
Watch December Metering Details
The next specified milestone is December, when OpenAI says the shared ChatGPT-Codex allowance begins for Plus, Pro and Business plans. Subscribers and business administrators can check OpenAI’s help center and account usage pages for implementation details, including how the allowance is displayed and which activities count toward it.
For Grok Bot, the source material identifies no announced reset, new limit, price change or timetable from xAI. Any further account or pricing changes would need to come from the company or its published plan terms. Until then, Musk’s post supports only the narrower conclusion that he described Grok Bot’s serving costs as unsustainable relative to revenue; it does not establish the scale of the problem or what xAI will do next.
Key Questions
Is Grok Bot included in every xAI plan?
No. According to xAI’s pricing page as described in the source, Grok Bot is included with Premium at $30 per month, Super at $100 and Ultra at $200. It is not included with Free or Plus.
Did Musk announce a Grok Bot usage cut or reset?
No specific change was announced in the quoted post. Musk said serving Grok Bot was “unsustainably high relative to revenue,” but did not confirm a cut, reset, price change or new limit.
What is OpenAI changing for shared accounts?
OpenAI’s help center says it limits how many paid accounts can be used on one device and how many subscriptions can be purchased with one card or device. The source says the rule applies to Go, Plus and Pro, but gives no numerical threshold.
How will ChatGPT and Codex usage be combined?
OpenAI says Plus, Pro and Business users will have a shared allowance across ChatGPT and Codex from December. The source does not spell out all allocation mechanics. It says unlimited Instant chats remain outside that meter.
Are flat monthly AI subscriptions ending?
The material does not report an end to flat monthly plans. It indicates that those prices increasingly sit alongside usage pools, plan limits and metering, so a monthly fee should not automatically be read as unlimited access to every model or feature.
