About GPT-5.1-Codex-Max
GPT-5.1-Codex-Max is OpenAI's first agentic coding model natively trained for multi-context-window operation via a process called compaction, allowing it to coherently maintain state across millions of tokens in a single long-running task. It is optimized for project-scale code work — refactoring large repos, autonomous debugging, and extended agentic loops — with enhanced reasoning and token efficiency. It is available inside the Codex platform and positions as the high-capability tier above the standard Codex models.
