Grok
xAI's assistant, built into X and grok.com. Grok 4.6 brings a 500K-token context and long-running agent workflows, with real-time X data, image generation and voice mode.
About Grok
Grok is xAI's assistant, and the only frontier chatbot wired directly into a live social network. If your questions are about what is happening right now — a breaking story, a sentiment shift, a thread you half-remember — Grok answers from the X firehose rather than from a stale index.
What is Grok?
Grok is built by xAI and shipped through X, standalone mobile apps and grok.com. The current flagship is Grok 4.6, released on 12 August 2026. It builds on Grok 4.5 with an explicit focus on long-running agents: multi-step research, analysing whole codebases, building applications and producing finished work artifacts rather than short answers. It carries a 500K-token context window. Alongside the text model sit Grok Imagine for image and video generation, a low-latency voice mode, and Grok Build 0.1, a cheaper coding-focused model. The house style is deliberately blunter and less filtered than rival assistants, which is either the point or the problem depending on your use case.
Key Features
- Grok 4.6: xAI's frontier model with a 500K-token context, tuned for multi-step agentic tasks rather than single-turn chat.
- Real-time X integration: Live posts, trends and public conversation as a first-class data source, which no other major assistant has.
- Grok Imagine: Image and short-form video generation, included from the $10 SuperGrok Lite tier upward.
- Voice mode: Fast, natural spoken conversation on mobile.
- Cheap API: Grok 4.6 at $2/$6 per million tokens undercuts most frontier competitors, with Grok Build 0.1 cheaper still for coding.
Who Should Use Grok?
Grok makes most sense for traders, journalists, marketers and analysts who need real-time social signal, and for developers who want frontier-class agent capability at a low API price. X Premium+ subscribers get it bundled, which makes it an easy add-on for people already paying. SuperGrok Lite at $10 is the value pick if you mainly want Grok Imagine. Teams in regulated or brand-sensitive environments should test the output style carefully first — Grok's looser filtering is a genuine consideration.
Pricing
There is a free tier on X and grok.com with tight limits. SuperGrok Lite, announced in March 2026, is $10/month and targets light users who mainly want Grok Imagine. SuperGrok is around $30/month, and SuperGrok Heavy around $300/month for the highest limits and earliest features. The API bills separately: Grok 4.6 at $2 per million input and $6 per million output tokens, Grok Build 0.1 at $1/$2 per million for coding, with older models such as Grok 4.3 cheaper still. Note that there is no Grok 5 — 4.6 is the current flagship.
Pros and Cons
| Pros | Cons |
|---|---|
| Only major assistant with live social-network data | Best usage limits need $30/month or more |
| 500K-token context and strong agent workflows | Heavy tier at ~$300/month is steep |
| API pricing undercuts most frontier rivals | Less filtered output is a poor fit for some workplaces |
| Image and video generation bundled from $10 | Smaller integration and plugin ecosystem |
Bottom Line
Grok has quietly become a serious frontier assistant rather than a novelty. Grok 4.6 is competitive on agentic work, the API is cheap, and the real-time X integration is a capability nobody else can copy. It is the best choice when timeliness matters most, and a strong second subscription alongside ChatGPT or Claude. It is not the right default for enterprises that need conservative, tightly filtered output.
