May 14 (Reuters) - OpenAI ‌said ​on ​Thursday its coding tool Codex was being added to the ChatGPT ‌mobile app, expanding access to the ⁠product as competition intensifies in the market ‌for AI code-generation tools.

Coding ‌tools have become an important way for AI companies to reach business ​customers, with OpenAI competing against rivals, including Anthropic, whose Claude Code tool ⁠has gained traction among developers.

Codex can perform tasks such ​as writing features, answering questions about codebase, fixing bugs and proposing ​pull requests for review. ‌The mobile app allows users to stay in the loop ⁠remotely after connecting to machines where Codex is running, enabling them to review outputs, ⁠approve changes and start new tasks.

The tool, launched ​as a desktop app in February, is being rolled out as a preview within the ‌ChatGPT mobile app on iOS and Android, OpenAI said. It ‌can connect only to macOS systems, ⁠with Windows support expected ‌to be ​introduced soon.
