Not because models are bad.
Because they have no context.
An enterprise building 200 agents across functions. Here's the honest math.
Build the graph once. Every agent after that is marginal cost.
With IW: The graph holds all context, rules, and logic. New agents just query it. The $40K collapses to ~$3K.
You could build a context graph in-house. Here's why most shouldn't.
Building the intelligence layer, the ontology, metrics engine, decision rules, traversal, MCP orchestration, and audit infrastructure, is a 12-18 month engineering project before your first agent works. You need knowledge engineers, graph architects, and domain experts working full-time. That's before you solve extraction, governance, or cross-functional discovery. The question isn't whether it's possible. It's whether that's the best use of your engineering team's time when the infrastructure already exists.
Build what's unique to you. Buy what's common underneath.
Your agents, your use cases, your competitive edge, that's yours to build. The ontology engine, metrics computation, decision rules framework, traversal, MCP orchestration, governance, and audit trail? That's infrastructure. You don't build your own database. You don't build your own cloud. Don't build your own context layer.
The consensus: Don't build context infrastructure. Buy it. Build agents on top.
Intelligence stays in the graph. Agents query it. Models are swappable.

Same graph. Same 4 tools. No retraining. No re-extraction.
First agent: 6 weeks. Every agent after: 11 days. Marginal cost: <10%.
The database is 5% of the value. The intelligence system is the other 95%.
