title: Model Profiles

**Command:** `/gsd-config --profile <quality|balanced|budget|adaptive|inherit>`

**Purpose:** Control which AI model each agent uses, balancing quality vs cost.

**Requirements:**
- REQ-MODEL-01: System MUST support 4 profiles: `quality`, `balanced`, `budget`, `inherit`
- REQ-MODEL-02: Each profile MUST define model tier per agent (see profile table)
- REQ-MODEL-03: Per-agent overrides MUST take precedence over profile
- REQ-MODEL-04: `inherit` profile MUST defer to runtime's current model selection
- REQ-MODEL-04a: `inherit` profile MUST be used when running non-Anthropic providers (OpenRouter, local models) to avoid unexpected API costs
- REQ-MODEL-05: Profile switch MUST be programmatic (script, not LLM-driven)
- REQ-MODEL-06: Model resolution MUST happen once per orchestration, not per spawn
