The X Subscription combines X Premium, Grok, and Cursor access under one account. X says there are five tiers, from Free to Ultra, and existing subscribers can link their X, Grok, and Cursor accounts as the gradual rollout reaches them (launch announcement, plan and rollout details).
Each tier includes a shared AI usage pool across Grok and Cursor. On Grok, that pool covers Chat, Imagine, Voice, Bot, and API access; higher tiers get larger allowances, which refresh weekly. If the allowance runs out, users can buy top-ups or wait for the refresh. Third-party models in Cursor are available at API list prices and do not draw from an included allowance (official pricing page).
The page lists Free, Plus, Premium, Super, Teams, and Enterprise, so it currently shows six options including organizational plans. Prices and feature-by-feature limits are not stated in the available page text.
