Governance Guide
AI Model Selection Framework Guide for Solution Architects (2026)
Model selection impacts cost, performance, and capability. This guide provides structured framework for comparing providers, evaluating tradeoffs, and documenting decisions.
Implementation Steps
- Define capability requirements: reasoning depth, output format, domain knowledge.
- Set cost constraints: per-request budget, monthly spending limits.
- Specify latency needs: real-time vs batch, acceptable response time range.
- Build comparison matrix: rate providers on capability, cost, latency, reliability.
- Document decision rationale: justify selection with tradeoff analysis.
