Grok, the AI assistant built by Elon Musk’s xAI, can be used directly inside X, through the web at grok.com, and in mobile apps. According to the source material, SpaceX acquired xAI on Feb. 2, 2026, and the operation now runs under the name SpaceX Super Intelligence LLC, with the official X account listed as @SpaceXSI.
Grok now spans several products, not just a chatbot
The source describes Grok as a broader product suite rather than a single assistant.
- Grok chat is available on grok.com, on iOS and Android, and inside the Grok tab on X.
- Grok Imagine handles image and video generation.
- Grok Voice is used for voice conversations.
- Grok Build is a coding-focused AI agent available in terminal, web and mobile versions.
- Grok Bot is a persistent AI agent with its own cloud computer that can keep working on assigned tasks.
Grok 4.7 is the active flagship model
Based on xAI’s developer documentation cited in the source, the only listed flagship text model is Grok 4.7, released on Sept. 21, 2026. xAI recommends using Grok 4.7 for everything other than voice, image and video tasks, including coding work.
Standard API pricing for Grok 4.7 is $2 per million input tokens and $6 per million output tokens. For prompts above 200,000 tokens, pricing changes to $4 for input and $12 for output. The model is positioned as a flagship system for coding and knowledge work, with a 500,000-token context window. A faster version is also available, with double the output speed and double the price.
The same source lists two additional model entries or capabilities:
| Model | Release date | API pricing | Positioning |
|---|---|---|---|
| Grok 4.7 | 2026/9/21 | $2/$6 per million input/output tokens; $4/$12 above 200,000 tokens in a single prompt | Flagship model for coding and knowledge work, 500,000-token context |
| Grok Build 0.1 | 2026/5/29 (public API beta) | $1/$2 per million input/output tokens; $2/$4 above 200,000 tokens | Described by xAI as its fastest coding model, 256,000-token context |
| Grok Voice 3.0 | 2026/10/14 | $0.08 per minute for speech-to-speech | Real-time voice conversation |
The official pricing page referenced in the source also lists a 20% discount for Batch API usage and a 10% surcharge for U.S. regional endpoints. Earlier models, Grok 4.6 and 4.5, remain available through the API, with the same standard input and output pricing as Grok 4.7.
On performance, xAI’s own published figures show Grok 4.7 scoring 46.3% on CursorBench 4.0, up from 40.4% for Grok 4.6 but below Anthropic Fable 5.1 at 51.8%. In the same comparison table, Fable 5.1 is priced at $10 per million input tokens and $50 per million output tokens.
The source says xAI also described Grok 4.7 as using a larger base model than 4.6, with reinforcement learning tuned toward tasks that can take several hours to complete, and with training aimed at the operating framework behind Grok Bot. On safety, xAI said Grok 4.7 uses a new protection system. In its internal HackerBench v0.3 security test, 3.3% of risky dual-use requests were allowed through, and the model scored 62.4% on LatchBio’s biosafety evaluation.
The X Subscription merged Grok, Grok Bot, Cursor and X Premium
On Oct. 12, 2026, U.S. time, SpaceXSI launched The X Subscription, combining Grok, Grok Bot, Cursor and X Premium into one subscription structure, according to the source. Paid plans share the same usage pool, meaning Grok usage inside the Grok app, the Grok tab on X, or Cursor is deducted from the same allowance.
The article lists five individual tiers, from free access to a $200 monthly plan:
| Plan | Monthly price | Taiwan monthly/annual pricing before tax | Usage and features |
|---|---|---|---|
| Free | $0 | Free | Limited daily Grok chats and a starter Cursor allowance |
| Plus | $8 | NT$249 for monthly billing, NT$186.75 for the first six months, or NT$2,490 annually | Base usage; chat, voice, Imagine, Grok Build, API access and Cursor; X blue check and fewer ads |
| Premium | $30 | NT$990 monthly, NT$495 for the first month, or NT$9,900 annually | 4x the Plus allowance; adds Grok Bot, latest models, video generation and cloud agents; most X pages without ads |
| Super | $100 | NT$3,390 monthly, NT$1,695 for the first month, or NT$33,900 annually | 15x the Plus allowance; priority model access during peak periods |
| Ultra | $200 | NT$6,690 monthly, NT$3,345 for the first month, or NT$66,900 annually | 50x the Plus allowance; earliest access to new products and models |
The source says U.S. dollar pricing and plan details come from the official pricing page. Taiwan checkout prices were observed by Chain News on Oct. 16, 2026, using a Taiwan account, and were listed before tax. Annual billing equals 10 months of monthly fees. A Teams plan is also available starting at $30 per user per month.
Two conditions are highlighted. First, using third-party models such as Anthropic or OpenAI inside Cursor is only available on Premium and above, and those calls are billed separately based on API pricing rather than being included in the subscription fee. Second, existing SuperGrok, Cursor or X Premium subscribers can keep their old plans and pricing, or switch in billing settings to the new structure, with prorated refunds for the old plan.
How the source breaks down plan selection
The article maps plan choices to different user profiles:
| Use case | Suggested plan |
|---|---|
| Occasional Grok questions on X and checking post context | Free |
| Daily research, writing and image generation, plus an X blue check | Plus at NT$249 per month |
| Handing full tasks to an AI agent, generating video and coding | Premium at NT$990 per month, including Grok Bot and Cursor Pro-level benefits |
| Engineers using Grok Build or Cursor all day and often hitting limits | Super or Ultra |
| Developers integrating Grok into their own products | Pay for API usage without a monthly subscription |
The source says Premium includes what used to be the benefits of SuperGrok, Cursor Pro and X Premium+, which together totaled $90 per month. For users already paying for both Cursor and X subscriptions, the new plan is described as usually more cost-effective. For those using only one of the services, the article suggests starting with Plus.
For coding users, usage still matters. The source says each new plan includes at least twice the Grok coding allowance inside Cursor compared with the equivalent older Cursor plan. But if a user mainly relies on Claude or GPT inside Cursor, those calls now require separate prepaid API spending and are not covered by the monthly fee.
For teams, the per-user monthly price matches the individual plan level. The source says the Teams plan is cheaper than the older Cursor Teams offering, includes three times the coding usage, and adds single sign-on, an admin console and unified billing.
Annual billing equals 10 months of monthly fees, or roughly an effective 17% discount from standard monthly pricing. The official pricing page, as cited in the source, says users can cancel at any time, but cancellation must be completed at least 24 hours before renewal to avoid the next charge.
How Grok is used across chat, media, voice, coding and agents
Chat on X, the web and mobile apps
Users can start on grok.com or by downloading the iOS or Android app. Inside X, access is through the Grok tab at x.com/i/grok. The source notes that xAI said on July 22 that Grok 4.5 had already been deployed on grok.com, X and the app, while the release notes for Grok 4.6 and 4.7 said those versions launched first in Cursor, Grok Build and the API.
Grok also has add-ins for Word, Excel, PowerPoint, Outlook and Google Workspace, allowing it to be called directly inside documents and spreadsheets. Since July, users have also been able to set automation schedules so Grok can run tasks on a timer or after receiving an email, then report back.
Grok Imagine for images and video
Imagine is Grok’s image and video generation feature. Plus includes Imagine, while the official pricing page cited in the source lists video generation as a Premium-and-above feature. Developers can also access it through the API, with image generation starting at $0.02 per image and video generation starting at $0.02 per second.
Grok Voice 3.0 for spoken interaction
The Grok app supports direct voice conversations through Grok Voice 3.0, released on Oct. 14, 2026. According to xAI’s announcement cited in the source, Grok Voice 3.0 handles millions of conversations per day in Tesla vehicles. It is also used in Starlink customer service centers to answer 20,000 calls per day, with about 70% resolved without human intervention. Developers can use the speech-to-speech API to build customer service systems or voice assistants.
Grok Build for coding
Grok Build launched in May as a terminal tool, was open-sourced in July, and became available on the web and mobile for all plans starting Aug. 19.
Grok Bot as a persistent cloud agent
Grok Bot launched in August. Each bot has its own cloud computer, can sign in to websites and tools used by the customer, and can keep working on a schedule. The source draws a clear distinction: Grok chat answers prompts, while Grok Bot is meant to take on an entire task. Access starts at Premium.
Developer access through the xAI API console
Developers can register in the xAI API console and create an API key, then call the model using the name grok-4.7. The API also includes server-side tools for web search, X search and code execution, billed by usage. The source gives two examples: web search costs $5 per 1,000 calls, and X search costs $5 per 1,000 returned posts.
