Among a programmer's tools, the JetBrains series of IDEs has always been an unshakable "heavyweight weapon." Today, this sword has officially been equipped with the strongest core from OpenAI. According to IT Home, OpenAI's programming tool Codex has now officially landed in all JetBrains development tools. This means that whether you are building complex backend logic in IntelliJ IDEA, optimizing AI models in PyCharm, or refining the front-end interface in WebStorm, you can directly summon this "AI programming assistant" to help.

The core highlight of this cross-industry integration is Codex's powerful "dual-mode" combat capability: it allows developers to smoothly switch between cloud-based intelligences and local programming environments, handling multiple software engineering tasks in parallel. Previously, Codex has already proven its strength in lightweight editors such as VS Code and Cursor. Now, its arrival in Rider, IntelliJ IDEA, and PyCharm has truly achieved a full-cycle AI closed loop from code planning, writing, to testing and publishing. Developers no longer need to run between multiple windows; they can complete the entire process with one click within the editor.

What has caught the attention of the tech community even more is that this sudden introduction of Codex is based on a brand-new GPT-5.2Codex. This level of capability injection has elevated the accuracy and logical understanding of code generation to a new dimension. To make it easy for users to get started, OpenAI provides extremely flexible "entry methods": you can log in using your existing ChatGPT account, or access via the OpenAI API Key, or even directly use the JetBrains AI subscription to start. The most exciting thing is that this feature is currently in a limited-time free phase, and each user has a personal promotional quota to use.

However, developers who want to experience this wave of computing power should pay attention to a small detail: JetBrains does not automatically "promote" this plugin by default. You need to manually install and enable the AI Assistant in the plugin market to unlock this digital brain hidden inside the IDE. This is not just a simple plugin update, but a milestone in the deep reshaping of productivity tools by AI.
