About

GPT-5.1-Codex-Max is the high-capability variant of the GPT-5.1-Codex series designed specifically for software engineering and agentic code workflows. It builds on the base GPT-5.1 architecture with a focus on long-horizon tasks such as full project generation, large-scale refactoring, and autonomous multi-step bug and test management. It introduces adaptive reasoning, meaning the system dynamically allocates more compute for complex problems and less for simpler ones, to improve efficiency and output quality. It also supports tool use (IDE-integrated workflows, version control, CI/CD pipelines) and offers higher fidelity in code review, debugging, and agentic behavior than general-purpose models. Alongside Max, there are lighter variants such as Codex-Mini for cost-sensitive or scale use-cases. The GPT-5.1-Codex family is available in developer previews, including via integrations like GitHub Copilot.

About

ui.sh is a terminal-first toolkit designed to help coding assistants generate high-quality user interfaces directly from the developer’s workflow, positioning itself as a way to “turn your terminal into a design engineer.” It is built specifically for use with AI coding tools such as Claude Code, Cursor, Codex, and similar agents, enabling them to produce better UI outputs without requiring separate design tools or manual iteration. It focuses on improving the quality of interfaces generated by AI by providing a structured system that guides layout, styling, and usability, helping developers avoid poorly designed or inconsistent UI results. It integrates directly into terminal-based workflows, allowing developers to prompt UI creation, iterate on designs, and refine components in real time within their existing development environment. Built by the creators of Tailwind CSS and Refactoring UI, the tool emphasizes clean, production-ready design output.
