# Grok 4.6: what xAI's new model is actually for

> xAI's Grok 4.6, out 12 August 2026, is built for long multi-step tasks at $2/$6 per million tokens.

*Not the smartest model on the market, and not trying to be. It's built to work through long jobs without giving up — and it's a third of the price.*

Most new AI models are announced as being cleverer than the last one. Grok 4.6, released by Elon Musk's xAI on 12 August 2026, was announced as being better at sticking with a job — which is a more useful thing than it sounds, and a good excuse to explain what 'agentic' actually means.

## What 'long-running agent' means

When you ask a chatbot a question, it answers once. When you give an AI a job — 'research these twenty companies and build me a comparison', or 'work through this codebase and fix the failing tests' — it has to take many steps in a row, deciding what to do next each time, without a human checking between steps. That is an agent, and the difficulty is not intelligence so much as stamina and self-correction.

xAI says Grok 4.6 does more checking of its own work on long tasks. That matters enormously. If a model makes a mistake at step 12 of a 60-step job and never notices, everything after that is built on the error. A model that catches its own slips is worth more than one that is marginally smarter but blunders on.

## How good is it, and what does it cost?

On a composite score made from nine different tests, Grok 4.6 reached 61 — level with OpenAI's GPT-5.6 Sol, and two points behind Anthropic's Claude Opus 5. That is genuine top-tier company.

The price is where it gets interesting: $2 per million tokens of input and $6 for output, against $5 and $30 for GPT-5.6 Sol. A million tokens is around 750,000 words. So you are paying roughly a third for a very similar score.

> **Info:** A cheaper model with a similar score is not automatically the better buy. What matters is whether it finishes your particular job correctly. The sensible test is to run a real task on both and compare results, not scores.

## The catch

Grok 4.6 is notably weak at command-line work — the text-based way developers control computers — scoring 26% on a standard test for it. If your use involves an AI running commands and managing files, that is the thing to check carefully. For research, writing, analysis and building first drafts of software, the weakness matters much less.

There is also a reliability point worth knowing if you follow the news. xAI has been promising a successor, Grok 4.7, since late July, and it still had not arrived by mid-September. Musk said it needed more tuning because the model stopped too early on difficult tasks and did not check its own work carefully enough. All of that came from his posts rather than official documentation.

The practical advice: judge what you can use today. Grok 4.6 is a capable, well-priced model for long multi-step work that does not lean heavily on the command line. That is a real and useful thing, regardless of what is promised next month.

## Why 'steps' matter more than speed

xAI makes one claim that is worth understanding properly, because it is the most useful way to compare AI models for real work. On long jobs, Grok 4.6 reportedly reached the finish in about 53 steps, where Anthropic's Claude Opus 5 took 103 for comparable work. Fewer steps means less time, less cost, and — most importantly — fewer chances to go off course.

Think of it like asking two people to assemble flat-pack furniture. One reads the instructions carefully, makes a plan, and works steadily. The other starts immediately, gets halfway, realises a panel is backwards, and undoes fifteen minutes of work. Both may finish. One of them finishes in half the time with fewer scratches. Measuring AI by how quickly it starts talking misses this entirely.

The honest caveat is that these step counts are measured by the company selling the model, using its own setup. That does not make them false, but it does mean the number to trust is the one you get when you run your own real task on it. Most providers offer enough free or cheap usage to do exactly that before committing.

## Key takeaways

- xAI released Grok 4.6 on 12 August 2026, a month after its previous model.
- It is built for long jobs — research across many steps, working through a codebase, building a first version of an idea.
- It costs $2 per million words of input and $6 for output, roughly a third of what comparable models charge.
- On a nine-test composite score it is level with OpenAI's GPT-5.6 Sol and just behind Anthropic's Claude Opus 5.
- Its biggest weakness is command-line work, where it scores 26% on a standard test.

## FAQ

### What is Grok 4.6 good for?
Long multi-step tasks: research across many sources, working through a codebase, or turning an idea into a first working version. xAI says it checks its own work more on extended jobs.

### How much does Grok 4.6 cost?
$2 per million input tokens and $6 per million output — roughly a third of GPT-5.6 Sol's $5/$30 for a similar composite score.

### Is Grok 4.6 as good as ChatGPT or Claude?
On a nine-test composite it matches GPT-5.6 Sol and trails Claude Opus 5 by two points. It is clearly weaker at command-line work.

### Is Grok 4.7 available?
No. It has been delayed repeatedly since late July 2026, with Musk citing tuning problems around task management and self-checking.
