Since debuting last spring, OpenAI's Codex coding app has seen standalone Mac and Windows releases, so it was only a matter of time before OpenAI gave people a way to access their Codex projects on mobile. Starting today, all ChatGPT users, including those using the chatbot through OpenAI's Go and Free tiers, can use the software through the ChatGPT app on Android and iOS. To be clear, you won't be using Codex to program on your phone. Instead, the ChatGPT mobile app is acting here as a intermediary between you and whatever environment you've set it up for your coding projects, whether that be a physical device like a Mac mini or a remote space managed by your company. That might seem limiting, but it does mean your files, credentials and permissions stay secure on the machine where Codex is running.

Codex can now manage several AI assistants to complete complex tasks. Since last spring, OpenAI has offered Codex . What started life as the company's response to Claude Code is becoming something more sophisticated with the release of a new dedicated macOS app. At its most basic form, Codex is a programming agent capable of writing code for users, but now it can also manage multiple AI assistants that can work together to complete more complex tasks. OpenAI gives an example of how this could work in practice.

"Our goal is to make ChatGPT the smartest assistant, and now we're really enhancing its capabilities in terms of what it has access to from the web," Fry tells MIT Technology Review. The feature is available today for the chatbot's paying users. While ChatGPT search, as it is known, is initially available to paying customers, OpenAI intends to make it available for free later, even when people are logged out. The company also plans to combine search with its voice features and Canvas, its interactive platform for coding and writing, although these capabilities will not be available in today's initial launch. The company unveiled a standalone prototype of web search in July.
