Infrastructure & Architecture
Infrastructure & Architecture
Foundation & Build — the physical and logical base that everything else in an AI system runs on.
Role of this domain
Infrastructure & Architecture is the Foundation of the five-domain framework. No matter how good your prompting or orchestration strategy is, the whole system becomes unstable if the infrastructure underneath it is weak.

Core components
| Component | Description |
|---|---|
| Compute resources | GPU/NPU servers, cloud infrastructure optimization |
| Model selection & tuning | Choosing the right LLM for the job, fine-tuning, quantization |
| AI model benchmarking | Quantitative analysis of intelligence, speed, and price based on Artificial Analysis |
| Data pipelines | Real-time data collection and cleaning for AI training and inference |
| Vector DB | Optimizing vector databases for semantic search |
| MCP servers | Context management based on the Model Context Protocol |
Core strategy: the model mix
The goal is not simply to “own” models — it’s to run a model mix strategy matched to specific purposes.
- Large models: complex reasoning, creative work
- Small models: fast responses, cost-efficient classification and summarization
- Specialized models: domain-specific tasks such as code generation, image understanding, and speech processing
Health check questions
“Does our infrastructure layer run a model-mix strategy that actually fits its purposes?”
- Is GPU/cloud spend optimized within budget?
- Does vector DB response time meet SLA in production?
- Have we chosen the right strategy among fine-tuning, prompt engineering, and RAG?
- Are MCP servers providing context reliably?
