Gateway Rule: Meter the Workload Before You Sign the Pass
Should an agency buy metered per-token inference or a fixed-duration unlimited pass for a given client workload? Model the workload's token profile and concurrency ceiling first, then choose metered or pass-based billing to match it, never the reverse.

“Should an agency buy metered per-token inference or a fixed-duration unlimited pass for a given client workload?”
Model the workload's token profile and concurrency ceiling first, then choose metered or pass-based billing to match it, never the reverse.
Agencies buy the cheapest headline rate, then discover the pass's session cap throttles a parallel batch job or the metered bill triples when an agent retries a long context, and the overrun lands on the retainer instead of the client.
Fixed-duration passes such as endlesstokens sell unlimited tokens inside a 1-hour to 3-day window but cap each key at two parallel sessions and a 128K context, so a workload that needs 20 concurrent streams or 256k context will not fit the pass regardless of price. Metered gateways like TokenDelivery.ai serve Gemma 4 26B A4B at a 256k window with byte-for-byte deterministic outputs, which matters when a client deliverable has to be reproducible in an audit. Forrester's Tokenomics analysis warns that agentic workflows billed by token consumption can destroy margin if they are not audited at the design stage, and token optimization alone can cut per-task cost by 50 percent or more, so the billing model has to follow the measured shape of the work.
- •A client workflow runs high-volume, bursty inference (batch content generation, overnight enrichment jobs) where token counts swing 10x week to week
- •The agency is quoting a retainer that must absorb inference cost without a pass-through line item
- •Delivery teams are evaluating an OpenAI-compatible gateway and comparing per-token pricing against time-boxed passes
- •A single client account has crossed the point where monthly inference spend is visible on the P&L
