AI Model Evaluation Framework

Work through these 5 phases before shortlisting specific models — the answers eliminate bad fits fast.

DEFINE BEFORE YOU EVALUATE

mustUse case type

Chat, RAG, agents, code gen, classification, extraction? Each demands different benchmarks and model families.

mustData sensitivity

HIPAA, GDPR, ITAR, SOC2? Determines whether on-prem is required vs optional, and which providers are in scope.

mustLatency requirement

Real-time (<500ms), interactive (<5s), or batch? Rules out certain model sizes and inference stacks entirely.

importantThroughput

Requests/day or concurrent users? Determines GPU count, context caching strategy, and rate limit headroom.

importantLanguage needs

English-only or multilingual? Single-language use cases rarely need Qwen's breadth or mGPT variants.

nice to haveFine-tuning plan

Domain-specific training? Affects which base model and licence you pick — some prohibit fine-tuned commercial use.
