AI Orchestration

The coordination of multiple AI models, tools, and data sources in a unified pipeline to accomplish complex tasks that no single model can handle alone.

How It Works

AI orchestration is how you build real AI products — by combining multiple components rather than relying on a single LLM call. A typical orchestrated pipeline might: (1) use a small, fast model to classify the user's intent, (2) route to a specialized model or tool based on intent, (3) retrieve relevant context from a vector database, (4) call a powerful model with the enriched context, (5) validate the output with a guardrail model, (6) return the result. Orchestration frameworks include LangChain (Python/JS, general purpose), LlamaIndex (data-focused), Semantic Kernel (Microsoft/.NET), and custom pipelines. The key decisions are: which model for each step (use cheap models for classification, expensive ones for generation), how to handle failures (retry, fallback, escalate), and how to manage state across steps. For production systems, orchestration also means: observability (trace each step to debug failures), caching (avoid redundant LLM calls), rate limiting (stay within API quotas), and cost tracking (know exactly what each request costs across all models and services used).
