Grok 4 Fast – a fast version of the AI model launched by xAI

What is Grok 4 Fast？

Grok 4 Fast is a fast version of the AI model launched by xAI. Its biggest advantage is speed—up to 10 times faster than the standard version, with a generation rate of 75 tokens per second. It can quickly complete simple queries, basic code generation, and other lightweight tasks, significantly improving efficiency. Currently in early access beta testing, the model is expected to be rolled out to more users in the future, potentially replacing the older Grok 3 and being adapted for mobile applications.

Key Features

• Language generation: Quickly generates various text formats, including stories, articles, and poems, while also offering creative writing ideas and inspiration to help users efficiently complete writing tasks.

• Code generation: Produces basic code snippets in multiple programming languages to meet simple development needs. It can also analyze user-provided code and suggest optimizations to improve efficiency and readability.

• Information retrieval: Rapidly answers factual questions across history, science, geography, and other fields. It can also quickly organize and summarize user-provided data or information, extracting key points to help users efficiently access and process knowledge.

Performance of Grok 4 Fast

• High response speed: Generates up to 75 tokens per second—10 times faster than the standard Grok 4.

• Limited depth and detail: To achieve faster responses, the model sacrifices some content depth and detail. For example, when generating SVG images of robots, it uses simplified forms to ensure speed.

• Best suited for simple tasks: Excels in scenarios such as quick queries, basic code generation, and fast information retrieval, greatly enhancing efficiency.

• Limitations with complex tasks: Less comprehensive than the standard version when handling complex or highly creative tasks. For example, when generating SVG code for an Xbox 360 controller, results appear abstract, and it may stumble on even simple queries like “Who are you?”.
