OpenAI’s GPT-5.2-Codex now available across major IDEs through GitHub Copilot, expanding enterprise AI coding capabilities beyond VS Code.

GitHub has rolled out GPT-5.2-Codex support to Visual Studio, JetBrains IDEs, Xcode, and Eclipse, marking a significant expansion of OpenAI’s advanced coding model beyond its initial VS Code deployment. The update, announced January 26, 2026, makes the agentic AI model accessible across virtually every major development environment.

The expansion comes just 12 days after GPT-5.2-Codex became generally available in GitHub Copilot on January 14. OpenAI first released the model on December 18, 2025, positioning it as a specialized tool for software engineering and cybersecurity applications.

What Developers Get

GPT-5.2-Codex is now accessible through the chat model picker in ask, edit, and agent modes across supported platforms. Minimum version requirements apply: Visual Studio 17.14.19 or 18.0.0+, JetBrains plugin 1.5.61+, Xcode 0.45.0+, and Eclipse 0.13.0+.

The model improves on GPT-5.2 with better handling of long-horizon tasks and large code changes—particularly useful for enterprise refactoring projects. Windows environment support and cybersecurity capabilities also received upgrades, addressing common pain points in corporate development workflows.

Enterprise Adoption Hurdle

There’s a catch for business users. Copilot Business and Enterprise administrators must manually enable GPT-5.2-Codex through the policy settings before their teams can access it. Individual Copilot Pro and Pro+ subscribers get immediate access.

This opt-in requirement suggests GitHub is giving enterprise IT departments control over AI model adoption—a smart move given ongoing corporate debates about code security and intellectual property when using AI assistants.

The Bigger Picture

The timing is notable. On the same day as this IDE expansion, reports emerged claiming OpenAI has achieved 100% Codex usage internally—no human-written code required for certain projects. Whether that’s marketing hyperbole or genuine capability, it signals where the industry is heading.

Microsoft’s parallel announcement about GPT-5.2-Codex in Microsoft Foundry on January 14 shows the coordinated push to embed this model across enterprise development stacks. For developers still on older IDE versions or waiting for admin approval, the rollout may take weeks to reach their daily workflow.
