What it cost

List prices of 2026-10-08, before Workers Paid's included monthly usage. Container CPU is an upper bound (it is billed on actual use). The container ran 159 s; the model was called 13 times (@cf/zai-org/glm-4.7-flash).

The workflow

What the voice says, what Jarvis is told, and what is checked: qodebase-browse.json (opens github.com).
