Model providers

By default every agent runs on the account you signed in with — your Claude subscription for Claude Code, your OpenAI account for Codex, and so on. In NeuroSquad this is called Default (harness login).

A model provider lets you choose the model yourself instead: connect a provider once in Settings → Providers, then pick a provider and model for each agent. Handy for trying a different model on a task, or running a cheaper one on routine work.

You can see which provider and model an agent uses on a small chip in its card, and what each one costs in Usage & costs.
