Grok 4.6, Explained Simply

Grok 4.6 is a newly released, highly capable AI model made by xAI. It is designed for people who need heavy-duty help with computer programming, complex multi-step tasks (often called "agentic" tasks, meaning the AI can take actions to reach a goal), and deep knowledge work.

What it does well

This model shines in three main areas: writing code, completing complex multi-step tasks on its own, and sorting through large amounts of information. It also lets you adjust its "reasoning effort"—meaning you can tell the AI to think quickly with low effort, or think deeply for harder problems using "high" or "xhigh" effort.

What it costs and what it can handle

• Context window: 500k tokens. A "token" is a piece of a word, so 500k tokens means it can read and remember hundreds of pages of text or code at one time.
• Inputs and outputs: It can read both text and images, but it can only write out text. There is no limit to how much text it can write back to you.
• Pricing: It uses a tiered pricing system based on how much text you give it at once (the "prompt"). If you give it under 200k tokens, it costs $2 per 1M input tokens, $0.50 for "cached" input (text it has seen recently and remembers), and $6 per 1M output tokens. If you give it over 200k tokens at once, the price goes up to $4 for input, $1 for cached input, and $12 for output.

Worth knowing

• Currently, Grok 4.6 is only available through the xAI API. An API is a tool for software developers to connect the AI into their own apps, so everyday users cannot chat with it directly just yet.
• While it can look at images, it cannot generate or output images itself—it only replies with text.
