Grok AI: What It Can Do, How It Works and How Much It Costs

August 18, 2026 3 Min Read

Grok AI is no longer just another chatbot. With the arrival of Grok 4.5, xAI is pushing Grok toward coding, AI agents, research and everyday work. The latest model has a 500,000-token context window, configurable reasoning and tools such as web search, X search, code execution and function calling.

But Grok 4.5 is only one part of the platform. Grok can also generate images and videos, analyse files, handle voice conversations and connect with supported apps and data. So, what exactly can Grok do, and how much does it cost?

What Is Grok AI?

Grok is the AI assistant developed by xAI. Users can access it through the web, iOS and Android apps, while developers can use Grok models through the xAI API.

One of its biggest advantages is access to real-time web and X search. This allows Grok to look up current information instead of relying only on its built-in knowledge. It can also analyse uploaded PDFs, images, spreadsheets, audio and code.

What Is New in Grok 4.5?

Grok 4.5 is the latest flagship model from xAI, launched in July 2026. xAI describes it as a model built particularly for coding, agentic tasks and knowledge work.

The biggest change is its focus on completing actual tasks rather than simply answering questions.

Grok 4.5 supports low, medium and high reasoning levels, with high reasoning set as the default in the API. It also supports function calling, structured outputs, web search, X search and code execution.

Its 500,000-token context window also allows it to work with large amounts of information in a single task.

What Can Grok 4.5 Do?

Coding is one of the main areas where xAI is positioning Grok 4.5. It can help developers write, debug and work through software-engineering tasks, while its tool-use capabilities allow it to interact with external systems.

Grok 4.5 is also being used in Grok Build, xAI’s coding environment. It can work on software projects and more complex workflows instead of simply producing a piece of code in a chat window. xAI has also made Grok 4.5 available in Cursor and GitHub Copilot.

For regular users, Grok remains useful for writing, research, brainstorming and analysing information.

Grok AI Can Also Create Images and Videos

Grok is not limited to text.

Through Grok Imagine, users can create images and videos. The platform also supports voice conversations, allowing users to interact with Grok without typing every request.

This makes Grok useful for content creators who want to move between research, writing and visual creation without constantly switching AI tools.

How Much Does Grok AI Cost?

Grok is free to start, although the free version has usage limits. xAI’s current pricing page lists SuperGrok at $30 per month, with higher limits, access to Grok 4.5, connectors, image generation and video generation.

For developers, Grok 4.5 API pricing is currently $2 per million input tokens and $6 per million output tokens. Cached input tokens cost $0.30 per million tokens. Longer requests of 200,000 tokens or more use higher pricing.

Is Grok AI Worth Using?

Grok AI has become much more than a chatbot. Grok 4.5 gives the platform a stronger focus on coding, reasoning and AI agents, while web search, X search, file analysis, voice, image generation and video generation make it useful for everyday users as well.

For developers, Grok AI 4.5 is particularly interesting because it combines reasoning with tools and a large context window. For content creators and general users, the wider Grok platform offers a single place for research, writing and media creation.

The bigger question is no longer whether Grok can compete with other AI assistants. It is how much of your daily work you can actually move into one Grok workflow.
