The local time on February 5, OpenAI launched its latest coding model - GPT-5.3-Codex. This model has undergone significant upgrades based on the previous version GPT-5.2-Codex, not only improving coding performance but also integrating stronger reasoning capabilities and professional knowledge, making it show greater potential in handling complex tasks.

GPT-5.3-Codex achieved a "double leap" in performance, with a 25% improvement in running speed. Such an improvement allows it to efficiently handle various long-term tasks, especially excelling in complex scenarios involving research and tool usage. When using GPT-5.3-Codex, users can interact in real-time, guiding and collaborating as if working with colleagues, thus maintaining context continuity. This innovation provides a smoother user experience and offers more powerful support for developers and researchers.

OpenAI's technological advancement not only makes coding more efficient but may also change the way developers interact with AI. In today's rapidly developing technology environment, achieving more efficient workflows will undoubtedly help businesses and individuals stand out in the competition.

In addition, OpenAI has not stopped here. To further expand its influence in the market, OpenAI is actively hiring hundreds of "frontier deployment engineers" to win business from large enterprises. This strategy demonstrates OpenAI's ambitious vision for the future, aiming to maintain its leading position in the AI industry.

With the release of GPT-5.3-Codex, OpenAI once again shows us the limitless possibilities of artificial intelligence, and the future will be an era full of opportunities and challenges.
