Pathway 1: Training Data
Information baked into the model during training. Has a knowledge cutoff (often months old). Cannot be updated. Good for general knowledge, bad for current business information like hours, services, and pricing.
Pathway 2: Retrieval-Augmented Generation (RAG)
The agent retrieves external data before generating a response. Quality depends entirely on the retrieval source. Web scraping produces noisy, unstructured results. Querying the ACN produces clean, typed, verified results.
Pathway 3: Tool-Calling / MCP
The agent calls an external tool — like the ACN's MCP server — to get specific data. This is the highest-fidelity path: the AI specifies exactly what it needs ("find dentists in Miami accepting Cigna"), the tool returns structured results, and the AI synthesizes an answer from verified data.
