OpenAI has started rolling out the GPT-5.1-Codex-Max model, an AI agent designed to automate coding tasks. The new model is integrated into various Codex instances, including Terminal, IDE extension, Codex Web, and cloud services. It is intended to compete with Claude Code, the current market leader in AI coding. The GPT-5.1-Codex-Max model achieves a 74.5% success rate on the SWE-bench Verified benchmark and shows significant improvement in code refactoring tasks. The rollout is expected to be completed in the coming days. The GPT-5.1-Codex-Max model is designed to assist users in automating complex coding tasks, even for those who may not have extensive programming knowledge. This rollout aims to enhance the capabilities of OpenAI's coding tools, providing a more efficient and user-friendly experience for developers and non-developers alike.
