fullstack-builder / rank 28 of 41 / cycle 04

Dyad benchmark

Runs on your own machine against your own model key, which makes it one of the cheapest routes through the spec and gives it a code ownership score that hosted products cannot match: there is no platform to leave. The trade is variance, since throughput depends on the key you point it at, and there is no managed runtime to catch a bad deploy.

What agent performance looked like in practice
