Elon Musk said on Nov. 1 that Grok Bot’s serving costs were unsustainably high relative to revenue, without providing figures or announcing a specific change. In the same week, OpenAI published restrictions on sharing paid accounts and said some plans will use one allowance across ChatGPT and Codex starting in December. The developments point to closer management of usage, but do not establish that flat-price AI subscriptions are ending.
Elon Musk said Nov. 1 that the cost of serving Grok Bot was “unsustainably high relative to revenue,” while OpenAI introduced new rules for paid account use and announced that some subscribers will share an allowance across ChatGPT and Codex from December. The changes sharpen questions about what a fixed monthly AI subscription includes, but neither company has announced that its subscription model is ending.
Musk’s remark came in response to an X user asking for a Grok Bot reset after users reported that their usage had run out quickly that week. Musk gave no cost, revenue or margin figures, and did not say whether xAI had changed the bot’s limits, pricing or reset policy. His statement referred to Grok Bot, not Grok chat generally.
According to xAI’s pricing information cited in the source, Grok Bot is included with its Premium, Super and Ultra plans, priced at $30, $100 and $200 per month, respectively. Its use draws from a shared weekly pool that also covers Grok chat and certain coding-tool use. xAI describes agent activity as measured by steps and tokens, so a complex task can consume more allowance than a brief exchange.
OpenAI’s help center says it limits how many paid accounts can be used on one device and how many subscriptions can be purchased using one payment card or device. The published rule covers Go, Plus and Pro plans, but the source says OpenAI has not published numerical thresholds. OpenAI also says Plus, Pro and Business subscribers will have a shared token-based allowance across ChatGPT and Codex beginning in December. The source says unlimited “Instant” chats remain outside that meter.
What Subscription Limits Mean for Users
These changes matter because the monthly price alone may not tell subscribers how much intensive use they can expect. Agent tasks can involve extended work and repeated model calls, while usage allowances may be shared across more than one product. A subscriber who uses both ChatGPT and Codex, for example, may need to track a combined allowance rather than treating each service as separate.
For businesses, this makes the distinction between a seat fee and usage-based costs more relevant to budgeting. The source’s comparison of OpenAI model rates says output-token use can differ substantially between models, with the most capable model consuming allowance much faster than the cheapest. That supports the general point that the cost of a task varies; it does not provide a complete estimate of what any particular customer will spend.
For individual users, the practical question is whether their plan’s limits match their workload. Before paying for a higher tier, a reset or extra credits, customers can check the provider’s current usage page and plan terms. The available information does not show that all users will face a price increase or that every subscription is becoming metered in the same way.

How Flat-Price AI Plans Are Metered
OpenAI’s subscription changes came alongside increases to some usage allowances. On Oct. 29, Thibault Sottiaux, who works on Codex and ChatGPT, posted that limits would be doubled for Pro 100, Pro 200 and Pro 500 tiers and Business Premium. The source says OpenAI’s release notes described the change more narrowly: Pro 100 and Pro 500 received doubled Work and Codex allowance, while a planned reduction for Pro 200 was cancelled. The distinction between a social post and the company’s release notes matters when identifying the exact scope.
OpenAI previously offered a $200-a-month ChatGPT plan described as providing “unlimited access” to its best models, according to the source. In January 2025, chief executive Sam Altman wrote on X that OpenAI was losing money on Pro subscriptions because people used them more than expected. That historical statement is a comparison, not evidence of the current profitability or limits of the plan.
Subscription terms also vary by provider and product. The developments described here concern specific plans, account-sharing rules and usage pools; they do not establish a single policy across the AI industry. The source notes that Anthropic’s Claude subscriptions also have limits, but provides no detailed comparison of those limits.

What the Companies Have Not Said
Musk did not say what costs or revenues he was referring to, what prompted the comment, or whether xAI had already adjusted Grok Bot’s usage pool. His use of the past tense does not by itself confirm that a limit changed. The source also mentions reports of a post from Grok’s official account about adjusted allocations and a dashboard fault, but says it could not independently locate that post; those details remain reported rather than confirmed here.
OpenAI has not published the numerical thresholds for its new device and payment-card restrictions in the information provided. The exact December allowance, how it will be displayed to users, and how quickly different tasks will draw it down are also not specified. The source does not establish whether the changes will lead to higher prices, more frequent limits or different terms for particular customers.
Watch for Published Usage Rules
The next stated milestone is OpenAI’s planned shared allowance for Plus, Pro and Business users in December 2026. Subscribers will need to see the final account guidance and usage displays to understand how the combined ChatGPT and Codex pool works in practice. xAI could clarify Grok Bot’s weekly allowance or explain whether any change was made, but the source provides no announced date for further details.
Until providers publish clearer figures, customers can compare plan terms, monitor their usage and ask business sales teams for written information about allowances and overage costs. No industry-wide end to flat monthly pricing has been confirmed.
Key Questions
Did xAI announce a new Grok Bot limit?
No specific limit change was announced in Musk’s cited reply. He said serving Grok Bot cost more than its revenue could sustain, but did not describe a new cap, reset schedule or price.
When will ChatGPT and Codex share an allowance?
OpenAI says the shared allowance for Plus, Pro and Business plans is scheduled to start in December 2026. The source does not give the exact allowance amounts.
Which OpenAI plans are covered by the account-use rules?
The cited OpenAI help-center information covers Go, Plus and Pro. It says limits apply to paid accounts used on one device and subscriptions purchased using one payment card or device, but gives no numerical thresholds.
Do these changes mean AI subscriptions are ending?
No. The developments show more explicit account and usage management for particular products. They do not establish that fixed-price subscriptions are ending across OpenAI, xAI or the wider AI market.
