Stable is a slash-command layer that brings any model into an existing coding agent.
Stable lives inside the coding agent a developer already uses, as a small set of slash commands rather than a separate environment. The /model command chooses from more than 200 models or hands the choice to the router, /harness runs another harness inside the current session, and /reviewer sets any model as the reviewer for that session.
It is offered for Claude Code and Codex, with early access requested through the company's contact page. The pitch is that a developer keeps an editor, terminal, and habits unchanged while every model and harness is reachable from where the work already happens.
