What it really costs

Pricing model from the October 2026 comparison matrix. Figures marked (est.) are triangulated from secondary sources, not vendor-published; (secondary) figures come from secondary reporting.

The X Subscription (x.ai announcement dated 2026-10-12, rolled out 2026-10-12/13 — replaces SuperGrok for new sign-ups; some trackers recorded an Oct 2 page date, unresolved): Free $0; Plus $8/mo; Premium $30/mo (4x Plus usage; Grok Bot starts here); Super $100/mo (15x); Ultra $200/mo (50x). One shared WEEKLY usage pool across Grok + Cursor + X Premium (no absolute caps published — multiples of an unpublished Plus base only); 3rd-party models in Cursor billed separately at API list from first use (legacy Cursor plans included some — a real loss on switching). Existing SuperGrok/Cursor/X Premium subs keep legacy plans; switching is PERMANENT (support cannot undo) with prorated refunds on eligible plans; switch offers appear in billing settings (Chris's account 2026-10-13: Premium $20/mo for 6 months, then $30). API Grok 4.7 $2/$6 per 1M (<200K prompt), $4/$12 (≥200K)

From the research report

Landscape Report, October 2026 edition — §1.4.

Standout: Grok 4.7 released Sep 21, 2026 (xAI docs — primary): frontier model for coding, agentic tasks, knowledge work; 500K context; knowledge cutoff May 2026; reasoning controls; tools: function calling, web + X search (the X firehose is the differentiator for social/news monitoring), code execution. Voice API and Imagine (image/video) APIs available.

Pricing (current): Consumer (xAI pricing page via notcheapai.com, Sep–Oct 2026): Free $0; SuperGrok $30/mo; SuperGrok Plus $100/mo; Lite ($10) and Heavy ($300) reported by third-party trackers but not shown on xAI's own page — unverified; Business ~$30/seat/mo reported, secondary. API (primary: docs.x.ai, updated 9/21/26): Grok 4.7 $2 input / $6 output per 1M tokens below 200K prompt tokens; doubling to $4/$12 at ≥200K (the "200K prompt cliff"); cached input $0.50. Subscriptions and API billed entirely separately.

Key limits: Rebrand in progress ("© 2026 SpaceXAI LLC" on official pages, coverage still says xAI — expect confusion). Consumer page says Grok 4.6 while docs list 4.7. High reasoning-effort token consumption raises real per-task costs (TechRepublic, 9/22/26). No published enterprise SLA tier found.

Key limits

Latest Grok models require Premium or above; Grok Bot not on Plus; "200K prompt cliff" doubles API cost; rebrand confusion (xAI → SpaceXAI → SpaceXSI in 2026); no enterprise SLA found
