OpenAI Codex Now Embedded in JetBrains IDEs for Smarter Coding
624Developers using JetBrains IDEs can now access OpenAI’s Codex AI directly within their coding environment. This new integration means programmers can plan, write, test, review, and deploy code without switching between tools. It’s a big step toward more intelligent, AI-assisted coding right inside popular JetBrains editors.
Seamless Integration with Popular JetBrains Tools
The integration was announced on January 22, and it’s available starting with JetBrains IDE version 2025.3. Supported IDEs include IntelliJ IDEA, PyCharm, WebStorm, and Rider. Developers can use Codex with a JetBrains AI subscription, a ChatGPT account, or an OpenAI API key—all within the same AI chat interface.
This makes it easier for programmers to collaborate with AI while working on complex projects. They can ask questions, get code suggestions, or even delegate tasks directly inside their favorite IDEs. The goal is to streamline the development process and boost productivity.
Powered by Advanced AI for Better Coding and Security
The AI model behind this feature is GPT-5.2-Codex, OpenAI’s most advanced coding engine to date. It can handle complex tasks like large code refactors, migrating codebases, or building new features. OpenAI claims this model is especially strong in cybersecurity, helping teams identify vulnerabilities and reason about exploits more effectively.
Developers can choose different modes of interaction, from simple question-and-answer to more autonomous actions. They can also switch between AI models and adjust the reasoning depth, speed, and cost depending on what they need for each task. This flexibility makes the tool adaptable for various development scenarios.
The Codex feature is temporarily free when accessed through JetBrains AI, including free trials or tiers. This promotional offer started on January 22 and will last until the allotted credits are used up. However, using a standard ChatGPT account or an OpenAI API key does not include this free access, as JetBrains clarified.
Overall, this move aims to bring smarter, AI-powered coding assistance directly into the IDEs developers already rely on. It promises to make coding more efficient, secure, and collaborative, marking a new chapter in AI-assisted software development.
