GPT-5.2 Codex

GPT-5.2 Codex is an agentic coding model engineered to address the practical challenges of enterprise software development. By functioning as a reasoning engine rather than a simple autocomplete tool, it is designed to handle the complexities of large repositories, legacy code, and evolving project requirements. The model is built to process diverse inputs, including partial documentation, diagrams, and screenshots, allowing it to provide security-aware assistance that integrates directly into professional development workflows.

Optimized specifically for agentic coding tasks, this model serves as a specialized iteration within the broader GPT-5.2 family. It is deployed across major integrated development environments and enterprise platforms, where it supports developers in managing dependencies and streamlining security reviews. By focusing on sustained reasoning and context-heavy engineering tasks, the model provides a robust solution for teams looking to maintain high standards of code quality and security within their existing infrastructure.
