The economic model

Preferred economic model — updated 4 October 2026

The brand pays for design/build, deployment and agreed management/software service. The separate performance unit is persona CPC: a verified, user-initiated outward handoff click from the sponsored-agent thread to an approved destination. The platform retains the entry click. The GPT Agency does not levy another performance fee merely for entering or talking. This supersedes the earlier voice-margin-led proposal; voice and hosting still need explicit funding, metering and limits.

Do not call this a completed purchase or a qualified lead. CPCC is no longer the billing label. Define event provenance, deduplication, invalid traffic, attribution window, approved destinations, disputes and reconciliation. No live billing or Sponsored Agent handoff-event integration is operating. Compare downstream purchases and incremental contribution separately.

Enterprise recommendation: deploy our software in the client's cloud, with client-owned provider accounts and direct payment of underlying usage where applicable. We provide specialist development and ongoing management with agreed rights, deliverables and a handover path. Sponsored-thread inference charges and event access must be confirmed with OpenAI. No platform revenue share is assumed.

The client deployment and cost plan explains concurrency, memory, provider charges, budget controls and handover. Average concurrency sets monthly volume; peaks set capacity. For example, 1,000 peak / 100 average concurrent sessions produce 4.32 million connected minutes in a 30-day month: $216,000–$864,000 of assumed provider allowance at $0.05–$0.20/minute, excluding media, cloud, agency and other costs. These are unmeasured planning assumptions, not a tariff, quote or achieved scale.

Our advantage over an internal build must be demonstrated through delivery time, recognisable character, quality, maintainability and equivalent ownership cost. A comparison with Meta or YouTube needs incremental outcomes and all acquisition costs; conversation length is not a substitute for effectiveness. See the working pitch brief.
