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.
