Pricing

Per model

Every request uses credits from your account, per model, with input and output counted separately: generating tokens costs far more than reading them. Credits per million tokens. Your credits are loaded by your administrator.

How a request is counted

For a request with P prompt tokens and C completion tokens, on a model with input price in and output price out per million tokens, at tier T:

cost = (P × in + C × out) / 1_000_000 × multiplier[T]

Audio has no published price yet: transcription is not billed today, and its price comes back here when the price list, the configuration and the invoice agree.

Tiers

The tier (X-Siati-Tier: slow|medium|fast|ludicrous, or the key's default) decides which machines may serve the request, the rate limit of your key, and a multiplier on the model's price. It does not change the order in a machine's queue. More in Tiers.
