According to Greg Brockman on Twitter, Codex is now demonstrating significant improvements in identifying security vulnerabilities within code. OpenAI is exploring trusted access programs specifically designed for defensive cybersecurity tasks, which could enable both enterprises and the open-source community to leverage Codex for producing more secure software. This development points to expanding business opportunities in AI-driven cybersecurity solutions and sets the stage for organizations to implement more robust, AI-assisted code review processes, as confirmed by OpenAI's official announcement (source: Greg Brockman on Twitter, Dec 18, 2025; OpenAI.com).

According to @lennysan and @gdb on Twitter, OpenAI utilized its Codex AI platform to build the Sora Android app, which rapidly became the #1 app globally, in just 18 days (source: https://x.com/lennysan/status/2001074732293300301). This demonstrates how Codex enables fast prototyping and deployment of complex AI-powered applications, significantly reducing development timelines. For AI businesses and developers, this highlights the practical advantage and market opportunity of integrating Codex or similar AI coding assistants to streamline mobile app development and quickly capture market demand.

According to @gdb, Codex is emerging as a powerful tool for modernizing legacy code, enabling enterprises to automate code refactoring, update outdated programming languages, and streamline software maintenance processes (source: x.com/1littlecoder/status/1967651403209265619). This development provides significant business opportunities for IT consulting firms and software vendors by reducing manual effort and technical debt in large codebases. Codex's AI-driven code transformation supports faster digital transformation, allowing organizations to respond rapidly to evolving technology trends and regulatory requirements (source: Greg Brockman, Sep 16, 2025).

According to Greg Brockman on Twitter, Codex AI is now becoming deeply integrated into the entire software development stack, offering features such as automated code review and seamless integration between local and remote development environments (source: Greg Brockman, Twitter, August 28, 2025). This evolution enables developers to leverage Codex not just for code generation, but also for improving code quality and streamlining workflow across distributed teams. Businesses can benefit from reduced development cycles, fewer errors, and improved collaboration, highlighting Codex's expanding role in enterprise AI-driven DevOps solutions.

According to Greg Brockman on Twitter, OpenAI's Codex is now accessible to ChatGPT Plus users, introducing a highly requested feature that allows users to enable internet access for the AI agent with granular control over HTTP methods and allowed domains (source: Greg Brockman, Twitter, June 3, 2025). This update enables developers and businesses to leverage real-time data and web resources directly within ChatGPT, significantly expanding opportunities for AI-driven automation, workflow integration, and up-to-date information retrieval. The new controls enhance security and customization, making Codex a more robust solution for enterprise and application development in dynamic environments.
