OpenAI has released an updated version of its artificial intelligence-powered coding assistant, GPT-5-Codex, which features improved review capabilities.
The updated version, which is available today, also allows developers to code from anywhere, be it through a terminal, web or smartphone, according to the Microsoft (NASDAQ:MSFT) and SoftBank-backed (OTCPK:SFTBY)(OTCPK:SFTBF) startup.
“GPT‑5-Codex has been trained specifically for conducting code reviews and finding critical flaws,” OpenAI said. “When reviewing, it navigates your codebase, reasons through dependencies, and runs your code and tests in order to validate correctness.”
Coding agents have surfaced as one of the primary ways to monetize AI models.
“In addition to creating aesthetic desktop apps, GPT‑5-Codex also shows significant improvements in human preference evaluations when creating mobile websites,” OpenAI said. “When working in the cloud, it can look at images or screenshots you provide as input, visually inspect its progress, and display screenshots of its work to you.”
Codex is included in multiple OpenAI subscription plans, including ChatGPT Plus, Pro, Business, Edu and Enterprise.
