SpaceXSI Folds Grok, Cursor, and X Premium Into "The X Subscription" - New Cursor Plans Put Third-Party Models Outside the Flat Fee

On October 12, 2026, SpaceXSI announced The X Subscription, a single contract covering Grok, Grok Bot, Cursor, and X Premium¹. New customers can sign up from the day of the announcement, and the company plans to extend it worldwide over several days. At the same time, the existing SuperGrok, Cursor, and X Premium plans stopped accepting new subscribers.

For anyone who relies on Cursor at work, the bundle itself matters less than how billing now works. The usage included in the monthly price of the new plans is for Grok models. Using third-party models in Cursor requires Premium or a higher tier, and that usage is metered at API list price.

The announcement page’s title names the publisher as “SpaceXSI,” while the copyright line at the bottom reads “SpaceXAI LLC”¹. In earlier coverage, this site referred to the company’s AI unit as SpaceXAI after it absorbed xAI. This article follows the announcement page title and uses SpaceXSI.

Five plans, one usage allowance for Grok and Cursor

The five plans are priced per month in US dollars, excluding tax¹².

Plan	Monthly price	Included usage
Free	$0	Limited
Plus	$8	Base
Premium	$30	4x Plus
Super	$100	15x Plus
Ultra	$200	50x Plus

SpaceXSI describes Premium as combining what SuperGrok, Cursor Pro, and X Premium+ offered, which it says added up to $90 a month when bought separately¹. The Free plan comes with day-to-day Grok access and an entry-level allowance for Cursor’s coding agents.

Grok and Cursor draw on the same allowance. Within Grok, usage of Chat, Voice, Imagine, and Grok Bot counts against it, and it resets every week. Once it runs out, users can buy more (top-ups) or wait for the reset. There is no requirement to split it: the whole allowance can go to one product, so whatever goes unused in Grok is available to Cursor. SpaceXSI claims that every tier gives at least double the coding usage with its own models compared with the equivalent Cursor plan.

Third-party models in Cursor move outside the flat fee

This is the part with a large practical impact. Under the new plans, only Premium and higher tiers can use third-party models in Cursor, and that usage is charged on top of the monthly fee at API list price¹. Cursor’s pricing page likewise says that Plus is limited to Grok models and that Premium and above carry no allowance for third-party models². In its comparison table, the row “Third-party models at API list price” shows ”—” for Free and Plus and a check for Premium, Super, Ultra, Teams, and Enterprise. Users can set a spending cap.

In other words, a new Cursor customer who mainly works with third-party models cannot budget on the monthly fee alone. The fee buys Grok model usage; anything else is added according to how much is consumed. Because the total depends on which models a team uses and how heavily, it helps to know the team’s usage by model before signing up.

Customers on an existing Cursor plan keep the third-party usage that their plan includes until they switch over to the new bundle¹. Switching shifts that usage to metered billing, so teams that lean on third-party models should estimate the metered cost before moving for the switching offers alone.

The set of third-party models is also changing. In August, OpenAI notified SpaceX that it would end its contract to supply models to Cursor, and as of October 14 its announcement page still gives November 12, 2026 as the planned end date³.

Team seats cost what individual plans cost

Teams buy Premium, Super, or Ultra seats at $30, $100, or $200 a month each, matching the individual prices¹. A seat carries the usage of the corresponding individual plan, and team plans also bring SSO, role-based access, SOC 2 compliance, usage analytics, and a single invoice for the organization. SpaceXSI says the per-seat price is lower than the previous Cursor Teams plans and that coding usage is three times higher.

In the comparison table on Cursor’s pricing page, SAML/OIDC SSO and a team marketplace for in-house plugins, skills, and rules are checked in both the Teams and Enterprise columns². Seat management via SCIM, access controls covering repositories, models, and MCP, and audit logs are checked only under Enterprise. According to SpaceXSI, Enterprise customers get one shared allowance for both products and administer Grok and Cursor in a single dashboard¹.

Existing subscribers can stay put, with no migration date yet

Current SuperGrok, Cursor, and X Premium subscribers can either keep what they have today, at the same price and with the same features, or switch to the bundle¹. The option to switch is being rolled out gradually and appears in account billing settings once it is available. Moving ends the old plan with a refund for the unused portion, and time-limited offers are attached to switching.

The old plans will not last indefinitely, however. SpaceXSI says those who have not switched will eventually be migrated, but it has not set a date and will notify customers before anything changes. Annual subscribers keep their plan until the term ends, and any later change applies only at renewal.

People who pay for more than one of the products separately can connect their Cursor, Grok, and X accounts in billing settings and receive a suggested plan based on what they have now. Neither the announcement nor Cursor’s pricing page says how adding seats to an existing Cursor Teams plan will be handled, for example whether those seats can stay on the old plan.

Two months from acquisition to a single price list

Cursor’s relationship with SpaceX began with a model training partnership in April 2026, and the acquisition closed on August 14. In July, before the deal closed, Cursor introduced Cursor Start, a lower-priced India-only plan built around its own models.

The new pricing can be read as taking that own-model-first approach and applying it to every new contract. If SpaceXSI’s description holds, teams whose work is mostly covered by Grok models may get more usage for the same monthly fee. Teams that have relied mainly on third-party models will need to set caps on metered usage and compare total costs against other tools, with OpenAI’s planned November 12 cutoff also in view.
