OpenAI released GPT-5.1-Codex-Max, a code-focused model trained on real software engineering workflows and optimized for extended development tasks.
Key features:
- Trained on real engineering tasks: pull request creation, code review, frontend development workflows.
- Designed for long-running tasks: better state tracking and continuity across complex coding sessions.
- Windows support: unlike the standard GPT-5.1 Codex (Unix-optimized), Codex-Max also targets Windows environments.
- Available now: accessible to *Plus, Pro, Business, Edu, and Enterprise* subscribers.
