December 19th.OpenAI Today, 19 December, the announcement of the launch of GPT-5.2-Codex is the most advanced and most advanced of allAgentProgramming AI Model,Training design specifically to address complex real-life software engineering issues。
The model integrates GPT-51-Codex-Max's end-operating capabilities based on GPT-5.2's universal intelligenceIts core breakthrough is the introduction of the "context compression" technique, which multiplys its efficiency when dealing with long-range tasks such as code reconstruction and migration。
For the actual work environment of the developers, GPT-5.2-Codex significantly enhanced the reliability of smart body coding in the original environment of Windows 10, Windows 11。
The improvement of visual performance is another highlight:THE MODEL NOW ALLOWS FOR A MORE PRECISE READING OF TECHNICAL CHARTS, UI SCREENSHOTS AND DESIGN SKETCHES。The developers need only provide design prototypes, which Codex can quickly convert to functional prototypes and assist in moving to the production stage。
On technical indicators, GPT-5.2-Codex updated its achievements in authoritative benchmark tests such as SWE-Bench Pro and Terminal-Bench 2.0。
By means of more reliable tools to call and optimize the accuracy of the facts, it can independently complete the full-process exercise created from the coding library to the Pull Request, and is considered a reliable "smart partner" for the developers to handle long-term coding tasks。
In operational cases, the GPT-5.2-Codex application capacity in the area of cybersecurity has also grown. In support of AI's value in defensive security work, OpenAI revealed a real case: Andrew MacPherson, the chief safety engineer at Privy, used the previous generation model (GPT-51-Codex-Max) in combination with the Cordex CLI toolReact Server Components successfully reproduced and dug into three unknown holes。
In the course of the study, AI smarts assisted in the completion of standard defence processes such as the build-up test environment, the reasoning attack surface and fuzzing. This case shows that an advanced AI system has been able to significantly shorten the cycle from “assumption” to “validation gap”。
In view of the potential dual-use risks associated with a strong code generation capability, OpenAI has adopted a more cautious approach in deploying GPT-5.2-Codex. Although the model has not yet reached the “high” risk level as defined in the internal “preparation framework”, the Government has introduced multiple protection mechanisms at the model and product levels。
1AI quotes Boven, OpenAI announced the launch of the “Trusted Access Pilot Scheme”. The plan will extend invitations to carefully scrutinized security experts and organizations to qualify for access to the higher-authority model for threat simulation, malicious software analysis and stress testing of critical infrastructure in a controlled environment。
OpenAI has now sent GPT-5.2-Codex in full to all ChatGPT pay users, covering all Cordex interfaces。For API users, OpenAI plans to gradually open access in the coming weeks。
