    GPT-5.3-Codex

    OpenAI

    Transform your coding experience with smart, interactive collaboration.
    GPT-5.3-Codex represents a major leap in agentic AI for software and knowledge work. It is designed to reason, build, and execute tasks across an entire computer-based workflow. The model combines the strongest coding performance of the Codex line with professional reasoning capabilities. GPT-5.3-Codex can handle long-running projects involving tools, terminals, and research. Users can interact with it continuously, guiding decisions as work progresses. It excels in real-world software engineering, frontend development, and infrastructure tasks. The model also supports non-coding work such as documentation, data analysis, presentations, and planning. Its improved intent understanding produces more complete and polished outputs by default. GPT-5.3-Codex was used internally to help train and deploy itself, accelerating its own development. It demonstrates strong performance across benchmarks measuring agentic and real-world skills. Advanced security safeguards support responsible deployment in sensitive domains. GPT-5.3-Codex moves Codex closer to a general-purpose digital collaborator.
