GitHub Copilot: Squad vs Fleet Comparison

·2026.06.08 02:59

Key point

This summarizes the technical differences and use cases between GitHub Copilot CLI's Fleet mode and the AI agent framework Squad.

Details

Fleet Mode (/fleet) is a feature built into GitHub Copilot CLI that automatically decomposes tasks and runs stateless sub-agents in parallel. It requires no separate setup, but memory is not retained across sessions.

Squad is an open-source framework developed by Microsoft's Brady Gaster that builds a team of named AI experts within a repository. These agents remember decisions, adhere to review protocols, and continuously learn the codebase.

The two features operate at different layers and create synergy when used together. Squad v0.10.0 introduces a hybrid dispatch mode that uses Fleet for read-heavy batch tasks, boosting speed by 2.9x, while using its own dispatching for write tasks.

Usage Guide:

  • Fleet: Suited for one-off parallel tasks
  • Squad: Suited for projects where agents need to accumulate knowledge over the long term
  • Using both together: Enables gaining both Fleet's speed and Squad's governance
