JetBrains has integrated xAI's Grok family of large language models (LLMs) into its integrated development environments (IDEs) to enhance its AI chat capabilities, offering models such as Grok 4, Grok 4.1 Fast, Grok 4.1 Fast (Non-Reasoning), and Grok Code Fast 1. This integration provides users with the flexibility to select the model that best suits their workflow for tasks like code refactoring, error fixing, and test generation. Users can access these models by ensuring they have an active JetBrains AI subscription or by starting a free trial directly from their IDE, after which they can interact with the AI chat to utilize the models' capabilities.
