Grok AI

The headline feature is that the app reads the live web and public posts on X as it answers. Ask about a developing story and it pulls current pages and posts rather than relying on a training snapshot. That makes it a natural fit for anything where the last few hours matter: sports results, market moves, product launches or a hashtag you just saw.

DeepSearch runs a multi-step research task instead of answering in one pass. It plans the question, gathers sources from around the web, and returns a written brief with the reasoning laid out. It's the tool to reach for when you want a grounded answer to an open question, and xAI limits how many sources it consults per run to keep the output tight.

Grok 4.7 is xAI's current flagship, released on September 21, 2026. According to xAI, it works longer on difficult tasks, checks its own work more carefully and manages a 500,000-token context window, which is enough to hold a large codebase or a long document in one prompt. It sits at the top of the price-performance curve on coding benchmarks, and it accepts text and image input.

Voice mode turns the app into a spoken assistant. You talk, it talks back, and it keeps the thread of the conversation without you typing a word. It's the fastest way to use the chatbot on the move, and it's one of the few features that reaches the free tier, with higher minutes on the paid plans.

The Imagine tools generate and edit images and produce short videos with native audio, up to 1080p on the higher plans. You describe what you want, and you refine the result by describing the change in plain language rather than wrestling with a timeline. Since March 2026 this sits on paid plans only.

The xAI API serves the same models through a single endpoint that works with the SDKs you already use, including the OpenAI format. You get text, code, image, video and voice endpoints, a free Playground, and usage-based pricing billed per token. For developers, that's the shortest path from trying Grok to shipping it.

Grok Bot gives you always-on agents that work inside your tools on their own computer and keep running around the clock. Add-ons for Outlook, Excel and Google Workspace bring Grok into the apps a team already lives in, so summarizing a thread or drafting a reply happens without a context switch.
