OpenAI brings Codex agent to ChatGPT mobile apps

openai integrated codex into the chatgpt mobile app, allowing users to view live environments, review outputs, approve commands, and manage development threads remotely from ios and android devices. the update, currently in preview, follows recent releases enabling background tasks on desktops and a chrome extension for browser sessions. this expansion aims to counter competition from anthropic, which launched a similar remote control feature for claude code in february. both companies are aggressively updating agentic coding tools to capture market share among businesses and developers.
