Faultmap vs Not Diamond

Not Diamond picks the cheaper model after the agent exists. Faultmap maps where the agent breaks before the build — routing is one technique inside the right-sized architecture, the proof is the product.

Side by side

Faultmapbefore the build

Not Diamondafter the build

When it runs

Before the build, in the design phase

At runtime, on live traffic

What it needs

Your goal, personas, data, and tools

A built agent making model calls

What it produces

A map of where it breaks, plus the first test suite

Lower average cost per call, model-level routing decisions

The question it answers

Where will this agent break, before I build it?

Which model should handle this call right now?

We do not replace Not Diamond. Faultmap runs one step earlier. Keep using Not Diamond after the build.
