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. Enter
