Grok Statistics: Usage, Benchmarks & Trends [2026]

In early 2025, Elon Musk’s Grok AI became one of the most discussed chatbots on the market. The AI chatbot, integrated into X (formerly Twitter), has seen rapid user growth in a short period.

Today, Grok refers to a series of AI models developed by xAI, including Grok-1, Grok-2, Grok-3, Grok 4, and the latest Grok 4.3.

In this article, you’ll learn the latest Grok statistics about user growth, visit trends, benchmarks, and other key insights into its expansion in the AI market.

Let’s first explore Grok statistics on the number of visits, user demographics & geography, and compare it with other generative AI models.

Grok’s popularity saw its most significant spike in February 2025, coinciding with the release of its 3rd version, when user growth jumped by 436.34% in a single month. Traffic to grok.com climbed again into early 2026, reaching 42.45 million unique visitors in March before cooling to 25.06 million by May. Overall, Grok shows a pattern of sharp growth around major releases, followed by moderate declines as adoption stabilizes.

Grok’s reach extends well beyond grok.com

The grok.com figures above cover only the standalone website. Grok’s true reach is far larger, because it is integrated more deeply into X than any frontier model is into any other social platform.

Grok reached around 117 million monthly active users by mid-2026, up from 64 million in early 2026, which makes it the third most-used AI assistant in the United States behind ChatGPT and Gemini. Grok has been downloaded close to 100 million times since launch across its iOS and Android apps, and records roughly 6.7 million daily active users.

Inside X, Grok powers the search bar, the “Explain” button on posts, the recommendation layer, and a dedicated assistant tab for Premium subscribers. It draws on X’s live firehose of about 550 to 600 million monthly active users for real-time context. In other words, the standalone web traffic is only a fraction of how many people actually interact with Grok.

Grok AI’s average visit duration of 11 minutes 20 seconds is the longest among these competitors, well ahead of Gemini’s 7 minutes 8 seconds and ChatGPT’s 5 minutes 54 seconds. This suggests that while fewer people visit grok.com directly, those who do tend to stay and engage longer.

xAI is also training Grok 5 on its Colossus 2 supercluster, with variants reported to reach up to 10 trillion parameters, though it has not yet been released.

Since its release, Grok has made significant progress in AI capability. Below is a breakdown of Grok 4.3 performance in key AI benchmarks, measured independently by Artificial Analysis.

Grok at Artificial Analysis Intelligence Index

The Artificial Analysis Intelligence Index ranks AI models based on reasoning, knowledge, coding, and mathematical abilities across nine evaluations. On the current version 4.1 of the index, Grok 4.3 scores 38, placing it 38th of 155 models and above the average of 29.

Grok 4.3 costs $1.25 per million input tokens and $2.50 per million output tokens, among the cheapest of the frontier models, and runs at 164.9 output tokens per second.

Grok Intelligence Evaluations

Grok 4.3 performs strongest in scientific reasoning. Below is a closer look at how it compares to other leading models across several Artificial Analysis benchmarks.

Grok 4.3 holds its own in scientific reasoning, scoring 90.1% on GPQA Diamond, close to the frontier leaders. It trails the strongest models on agentic coding benchmarks like Terminal-Bench, where the gap to GPT-5.5 and Claude Opus 4.8 is widest.

Grok Context Window

The context window defines how much information an AI model can process in one interaction. Grok 4 Fast’s limit is 2 million tokens, the largest among major models. In contrast, the current Grok 4.3 handles 1 million tokens.

All in all, Grok AI experienced rapid growth through 2025 and into early 2026, with grok.com traffic surging around each major release before cooling from its early-2026 peak. With around 117 million monthly active users and deep integration into X, Grok has established itself as the third most-used AI assistant in the United States. Benchmark tests still highlight its strong positions in scientific reasoning, even as the frontier flagships pull ahead on agentic coding.
