Frontier and GPT-5.3-Codex mark major OpenAI expansion

OpenAI has unveiled Frontier, a new enterprise platform designed to help organisations build, deploy, and manage AI agents capable of executing real operational work.

The launch reflects accelerating enterprise adoption, with businesses reporting measurable productivity gains across manufacturing, finance, sales, and energy operations through agent deployment.

Frontier addresses a growing gap between AI model capability and real-world implementation. The platform equips AI agents with shared organisational context, system access, governance permissions, and feedback learning mechanisms.

By integrating across existing cloud infrastructure, enterprise software, and data environments, Frontier enables AI coworkers to operate across workflows rather than within isolated tools.

Alongside the platform release, OpenAI introduced GPT-5.3-Codex, its most advanced agentic coding model to date. The system combines the coding strength of earlier Codex iterations with expanded reasoning and professional task execution.

Benchmark performance leads across SWE-Bench Pro, Terminal-Bench, OSWorld, and GDPval, reflecting gains in software engineering, computer use, and knowledge work automation.

Cybersecurity capabilities also advance with the release. GPT-5.3-Codex includes enhanced vulnerability detection training and operates under strengthened safeguards designed to support defensive research while mitigating misuse.

Together, Frontier and GPT-5.3-Codex position AI agents as scalable digital coworkers capable of executing complex technical and enterprise workloads end-to-end.
