About
GPT-5.3-Codex is OpenAI’s most advanced agentic coding model, designed to handle complex professional work on a computer. It combines frontier-level coding performance with advanced reasoning and real-world task execution. The model is faster than previous Codex versions and can manage long-running tasks involving research, tools, and deployment. GPT-5.3-Codex supports real-time interaction, allowing users to steer progress without losing context. It excels at software engineering, web development, and terminal-based workflows. Beyond code generation, it assists with debugging, documentation, testing, and analysis. GPT-5.3-Codex acts as an interactive collaborator rather than a single-turn coding tool.

About
Rune is a fast, keyboard-driven IDE for power users that brings code, terminals, CLI tools, language intelligence, debugging, and AI agents into one composable, multi-workspace environment. Built around the Unix way, it keeps powerful development tools close together without forcing developers into a mouse-heavy workflow. Rune ships with three built-in editing modes, a standard editor for users coming from VS Code, Cursor, or Sublime; modal editing for Vim and Neovim users; and an Emacs-style editor, with keybindings applied throughout the interface. Workspaces combine files, terminals, tasks, debugging, search, and language intelligence, and can run locally or on remote machines. Rune Agent lives in the same workspace as the code, where it can read and edit files, search the codebase, run commands, use tools, and maintain full conversations. It supports OpenAI, Codex, Anthropic, Claude, Gemini, Amazon Bedrock, local models, and custom OpenAI-compatible endpoints.
