xAI has created a new AI tool called Grok Code Fast 1, designed to assist programmers in writing code for apps and websites. It started on August 28, 2025, and for now, people can use it for free for one week on several popular platforms. Included in the list are GitHub Copilot, Cursor, Cline, Kilo Code, Roo Code, opencode, and Windsurf. After this free period, there will be a small charge to use it.
According to Elon Musk’s company xAI, Grok Code Fast 1 delivers high efficiency and can manage a broad variety of coding tasks. It is built on a brand-new design that makes it work faster than older tools. Grok Code Fast 1 works with a variety of programming languages such as TypeScript, Python, Java, Rust, C++, and Go. Programmers say it works with both the front end (what users see) and back end (the server side) of software.
One important fact is that this AI can use command line tools, help search for code bugs, and edit files directly. It is trained on a lot of code from real life, so it can solve problems and finish coding tasks without needing much help from people.
During company tests, Grok Code Fast 1 scored 70.8 percent on the SWE-Bench-Verified benchmark, which shows it is very good at working with real-world programming challenges.
If you try Grok Code Fast 1 during the free week, you do not need to pay. After the trial ends, using it will cost $0.20 (about 17 rupees) for every million input tokens, $1.50 (about 132 rupees) for every million output tokens, and $0.02 (about 1.7 rupees) for each million cached input tokens. If the tool needs to repeat tasks, it uses cached input tokens, which cost less.
Grok Code Fast 1 is designed to be useful for both beginners and experienced programmers. It can help create new projects, fix errors, and make coding faster and easier. The model is very helpful for anyone working alone or in a team. It will soon get updates, and xAI says it will keep improving its speed, support different types of media, and add new features.
This launch shows how AI is changing the way developers work. Grok Code Fast 1 offers speed, affordability, and simplifies coding for all users. Many people expect it will make a big difference in programming and software development. All details in this article are based on the latest official information and news reports
