What the platform fee covers.And what it never touches.
The platform fee is for closed-source models only. Open-weight models are hosted and open to you with no platform fee, so the choice of a closed model is the only thing that adds one.
Closed-source models
4% platform fee
Proprietary models carry a 4% platform fee on top of live catalogue token pricing. That fee is the only markup.
Open-weight models
No platform fee
Hosted open-source models are accessible with no platform fee at all. You pay catalogue token pricing and nothing more.

Is there a subscription?
No. Managed access runs on prepaid credits you top up when you want, and BYOK has no SingleAPI charge at all. There are no monthly fees, tiers or seats.
What does the 4% platform fee apply to?
Closed-source (proprietary) models only, charged on top of the live catalogue token pricing. Open-weight models have no platform fee, and BYOK requests have no SingleAPI charge on any model.
Can I use hosted open-source models?
Yes. Open-weight models are hosted and accessible under SingleAPI with no platform fee. You pay only the catalogue token pricing for them.
How is token pricing set?
The model catalogue is the source of truth, with per-million-token input, cached-input and output rates per model. We do not publish a static table that can drift from the live prices.
What does BYOK cost?
Nothing from SingleAPI. There is no wallet reservation, deduction or ledger entry. Your provider bills your own account for the usage.
