OpenAI’s Codex Programming Tool Launches on JetBrains IDEs

On January 23, 2026, it was reported by Neowin that OpenAI’s Codex programming tool has launched on JetBrains IDEs, allowing developers to use both cloud-based and local coding agents simultaneously.

OpenAI released the cloud-based Codex agent in May of last year, which can execute multiple software engineering tasks in parallel. In August, it added support for code editors like VS Code and Cursor.

The new extension is compatible with Rider, IntelliJ IDEA, PyCharm, and WebStorm, enabling users to plan, write, test, and deploy code without leaving their code editor.

Users can access Codex through a ChatGPT account, OpenAI API Key, or JetBrains AI subscription. Currently, it is in a limited-time free phase, with each user allocated a promotional quota. After this quota is exhausted, AI Credits will begin to be consumed, with the underlying technology based on GPT-5.2 Codex.

However, it’s important to note that the JetBrains IDEs do not automatically install or enable the AI Assistant plugin; developers must install it manually.
