AI BriefingInside JetBrains: The Company Reshaping How the World Writes Code
Key point
JetBrains is building AI workflows that boost developer productivity and code quality by integrating OpenAI's GPT-5 and other models.
Details
JetBrains is a company that provides tools used by 15 million engineers worldwide, including IntelliJ, PyCharm, and WebStorm. Recently, JetBrains has been integrating OpenAI models into its tools and workflows to help developers focus on design and architecture.
Internally, the company uses ChatGPT, GPT-5, and Codex, and for external customers, it has introduced GPT-5 into its coding agent Junie and AI Assistant. This allows developers to delegate repetitive tasks to agents and focus on more complex system design and review.
JetBrains' goal in adopting AI goes beyond simply increasing speed—it aims to secure sustainable engineering excellence.
- Speed: Reducing boilerplate code, minimizing context switching, and enabling fast iteration.
- Quality: Generating safe code that is easy to read and maintain.
The development environment of the future is expected to evolve toward engineers guiding AI agents, designing systems, and reviewing outputs, rather than typing code directly themselves.
