OpenAIaccelerated the pace again and launched GPT-5.2-Codex, its most powerful artificial intelligence model for programming to date.
The announcement comes less than a month after GPT-5.1-Codex-Max and marks a new step in the race for AI-powered software development.
OpenAI volvió a acelerar el ritmo y lanzó GPT-5.2-Codex
What GPT-5.2-Codex is and why it is key for developers
According to what OpenAI explained on its official website, GPT-5.2-Codex is designed to program autonomously and handle complex tasks during extended sessions.
The model is based on GPT-5.2 and incorporates all the features of GPT-5.1-Codex-Max, such as autonomous agents, terminal use, and advanced context handling.
Improvements in large-scale code
OpenAI emphasized that this version is more robust when performing refactoring, code migrations, and massive changes in large repositories. This allows it to iterate on complex projects even when plans change or intermediate errors arise.

In addition, GPT-5.2-Codex interprets technical diagrams, screenshots, and mock-ups better, transforming them into production-ready prototypes.
The focus on cybersecurity
One of the central pillars of the launch is cybersecurity. OpenAI states that it is its most robust model for detecting vulnerabilities. It can analyze code and complete architectures, identifying risks in popular frameworks with greater speed.
El salto más grande desde GPT-4
The company clarified that it doesn't reach a high-risk level within its Preparedness Framework and can't automate attacks without human supervision.
Is it a big leap compared with GPT-5.1?
In benchmarks such as SWE-Bench Pro and Terminal-Bench 2.0, improvements exist but are moderate, which is logical given how recent the previous model is.
The progress lies more in stability, security, and sustained work than in an abrupt performance leap.

Availability
GPT-5.2-Codex will begin to be gradually rolled out for paying ChatGPT users starting today.
It will also arrive on the API in the coming weeks, while OpenAI collaborates with the security community to reduce malicious uses.
