OpenAI brings Codex to mobile to compete with Claude Code

Published on May 16, 2026 | Translated from Spanish

OpenAI has integrated its Codex desktop tool into the ChatGPT mobile app, allowing users to give instructions to write code or control applications directly from their iOS or Android phones. This update aims to compete with the rise of Anthropic Claude Code and accelerate the company's business development, even leading to the closure of projects like Sora to concentrate resources.

A coding tool that fits in your pocket 📱

Codex on mobile allows you to execute commands, generate code snippets, and automate tasks without needing a computer. The integration leverages OpenAI's language models to interpret complex instructions and translate them into direct actions on applications. This reduces reliance on traditional development environments and brings assisted programming to a wider audience, albeit with the inherent limitations of a touch screen and mobile connection.

Goodbye Sora, hello competing with the neighbor 😅

While OpenAI shuts down Sora, its video generator that promised to revolutionize home cinema, it is now betting on turning your phone into a mini programmer. Because, of course, what the world really needed was the ability to write code while waiting for the bus. At least, if the code fails, you can always blame the 4G coverage instead of your own laziness.
