Codex AI Coding Tool Lands on ChatGPT Mobile

OpenAI is bringing Codex, its desktop AI coding tool, to the ChatGPT mobile app. The move allows users to access the code-writing and app-controlling tool directly from their phones. The expansion comes as OpenAI races to keep pace with Anthropic's Claude Code, which has surged in popularity. The company has reportedly been refocusing efforts, cutting back on other projects to prioritize its coding AI capabilities.
