Models and pricing

One key gives you access to every model below. To switch models, change the value of the model field, nothing else.

Available models

Rates are in credits per million tokens, input then output. 1 credit = $1 of usage.

List models from the API

The /v1/models endpoint returns the models your key can access. If you restricted a key with “Model Limits”, only those show up.

macOS / Linux
Windows (PowerShell)

curl https://api.kloria.dev/v1/models \
  -H "Authorization: Bearer $KLORIA_API_KEY"

(Invoke-RestMethod -Uri "https://api.kloria.dev/v1/models" `
  -Headers @{ Authorization = "Bearer $env:KLORIA_API_KEY" }).data.id

Calculating the cost of a request

A request’s cost depends on the tokens you send (prompt, history, attached files) and the tokens generated:

cost = input_tokens  × input_rate  / 1,000,000
     + output_tokens × output_rate / 1,000,000

Example with claude-sonnet-5, a request with 10,000 input tokens and 1,000 output tokens:

10,000 × 2  / 1,000,000 = 0.02 credit
 1,000 × 10 / 1,000,000 = 0.01 credit
                  total = 0.03 credit

With the 100-credit pack at €49.99, that request costs about 1.5 euro cents.

The actual cost of each request, with the token breakdown, is shown in the console under Usage Logs.

Pricing changes

During the beta, the model list and rates may change. This page is updated with every change. The rate applied is the one in effect when the request is made.
