xAI releases Grok 4.6 with an increased focus on long-term tasks, software development, and interactive applications. The model is available as of today.
Elon Musk’s company, formed by the merger of SpaceX and xAI, is wasting no time with new model launches. After barely a month, Grok 4.6 is already succeeding Grok 4.5. The new model is designed to perform complex tasks across multiple steps.
According to xAI, Grok 4.6 can research information, analyze data, work within a codebase, and transform an idea into a finished project. The model is immediately available in Grok Build, via Cursor (which was acquired by SpaceX), and via the company’s API console, although the latter option is not yet available in the EU.
Greater emphasis on long-term tasks
SpacexAI states that Grok 4.6 has undergone a longer training period than its predecessor. In doing so, the company used model-generated data for reasoning and technical concepts, supplemented by engineering data and a customized training method. The Grok 4.6 model was trained on knowledge work tasks and general coding assignments.
These include kernel optimization, web development, and computer-aided design. For longer assignments, Grok 4.6 reportedly tests and checks itself more frequently before proceeding. SpacexAI places its model on nearly equal footing with the latest models from OpenAI and Anthropic. On benchmarks, it scores slightly lower than GPT-5.6 Sol and Fable 5 Max, but better than Grok 4.5.
Cheaper but more controversial
Grok 4.6 aims to distinguish itself primarily on price. The cost of the base version starts at $2 per million input tokens and $6 per million output tokens. A fast variant costs double. xAI says it has implemented safety measures for applications such as vulnerability patching and AI research.
Much controversy surrounds the Grok models, and the company makes little effort to distance itself from it. After all, owner Elon Musk does not believe in ethical AI practices or imposing guardrails. Earlier iterations have been guilty of racist and anti-Semitic remarks, and in the EU, it has been reprimanded for distributing illegal nude images. Companies considering implementing Grok in their business environments would do well to keep this background in mind.
