Codex Security began as Aardvark, launched last year in private beta. Since then, we've significantly improved signal quality, reducing noise, improving severity accuracy, and lowering false positives, so findings better align with real-world risk.

OpenAI rolls out Codex Security, an AI agent that evolved from its research project Aardvark to automate vulnerability discovery, validation, and remediation

OpenAI is rolling out Codex Security, an AI-powered application security agent that finds, validates and proposes fixes for vulnerabilities.

We're introducing Codex Security. An application security agent that helps you secure your codebase by finding vulnerabilities, validating them, and proposing fixes you can review and patch. Now, teams can focus on the vulnerabilities that matter and ship code faster. [video]

OpenAI launches GPT-5.4, saying it is its “most capable and efficient frontier model for professional work” and its first with native computer use capabilities

The latest model comes with native computer use capabilities, allowing it to take on jobs across your device and applications.

GPT-5.4 sets new state of the art results on professional work and computer use, with strong gains on coding and tool use. 83.0% on GDPval 75.0% on OSWorld-Verified 57.7% on SWE-Bench Pro (Public) 54.6% on Toolathlon

OpenAI releases a Codex app for Windows with native sandboxing and support for developer environments in PowerShell, after launching a macOS app in February

At the start of February, OpenAI upgraded its Codex coding app to give it the ability to manage multiple AI agents.

To bring Codex to Windows, we built the first Windows-native agent sandbox. It uses OS-level controls like restricted tokens, filesystem ACLs, and dedicated sandbox users so agents can safely run in real Windows developer environments like PowerShell. Explore the OSS

OpenAI debuts a research preview of GPT-5.3-Codex-Spark, a smaller version of GPT-5.3-Codex that it claims generates code 15 times faster, for ChatGPT Pro users

ZDNET's key takeaways  — OpenAI targets “conversational” coding, not slow batch-style agents.  — Big latency wins: 80% faster roundtrip, 50% faster time-to-first-token.
