Topic. Is it possible to set different model to different squad members ??

Yes! Each agent can have a model preference set in their charter under the ## Model section. You specify a Preferred model and a Fallback.

We actually just merged a fix (PR #491) that adds persistent model preference support via Layer 0 config in .squad/config.json. You can set defaultModel for the whole team and agentModelOverrides for individual members.

Example in a charter:

## Model
- **Preferred:** claude-sonnet-4.5
- **Fallback:** gpt-4.1

And in .squad/config.json:

{
  "defaultModel": "claude-sonnet-4.5",
  "agentModelOverrides": {
    "backend-dev": "claude-opus-4.5"
  }
}

That said — the actual model used depends on your Copilot subscription and what models are available in your environment. Squad passes the preference along but the Copilot runtime makes the final decision.
