Enterprise AI coding grows teeth: GPT‑5.2‑Codex weaves security into large-scale software refactors

With the recent release of GPT 5.2, OpenAI updated other related models, including its popular coding model Codex, bringing more agentic use cases to its fold. 

GPT-5.2-Codex, which OpenAI called in a blog post “the most advanced agentic coding model yet for complex, real-world software engineer,” has been optimized for long-horizon work with agents and will have stronger cybersecurity capabilities. 

The model is an offshoot of GPT-5.2, optimized for agentic building. 

“GPT‑5.2-Codex represents a step forward in how advanced AI can support real-world software engineering and specialized domains like cybersecurity—helping developers and defenders tackle complex, long-horizon work, and strengthening the tools available for responsible security research,” the company said in its blog post. 

Enterprises can access the new Codex model “in all Codex surfaces for paid ChatGPT users, and working towards safely enabling access to GPT‑5.2-Codex for API users in the coming ...
