About
GPT-5.1-Codex is a specialized version of the GPT-5.1 model built for software engineering and agentic coding workflows. It is optimized for both interactive development sessions and long-horizon, autonomous execution of complex engineering tasks, such as building projects from scratch, developing features, debugging, performing large-scale refactoring, and code review. It supports tool-use, integrates naturally with developer environments, and adapts reasoning effort dynamically, moving quickly on simple tasks while spending more time on deep ones. The model is described as producing cleaner and higher-quality code outputs compared to general models, with closer adherence to developer instructions and fewer hallucinations. GPT-5.1-Codex is available via the Responses API route (rather than a standard chat API) and comes in variants including “mini” for cost-sensitive usage and “max” for the highest capability.

About
Session Orchestrator is a free, MIT-licensed workflow plugin for Claude Code, Codex CLI, Cursor and Pi. It reads repository context and issues, helps plan work, coordinates implementation in checked waves, and records verification results and remaining tasks for the next session. Workflows cover session startup, planning, execution, review and close-out. It runs locally with Node.js 24 or later. Enforcement varies by host: Codex file-scope and destructive-command rules are instructions rather than enforced hooks. Source code and documentation are available on GitHub.
