About

Command Code is a frontier coding agent that lives in the terminal, builds full-stack projects, ships features, fixes bugs, writes tests, and refactors code while continuously learning how each developer works. Powered by the meta neuro-symbolic taste-1 model and continuous reinforcement learning, it treats every accepted suggestion, rejection, and edit as a signal, turning recurring choices, structures, patterns, and tooling preferences into project-level skills and persistent memory. Instead of relying only on generic best practices, it learns code-review habits, style preferences, architectural decisions, package managers, libraries, and small conventions developers rarely document, then applies the relevant taste context in future sessions. Command Code supports interactive CLI work, headless prompts, automated execution, plan mode, background sandboxes, custom agents, checkpoints, and memory across sessions.

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.
