Models and pricing
Three models, one price list. All three are abliterated: the refusal behaviour has been removed from the weights, so they answer requests a stock model would decline.
Catalog
| Model id | Name | Use it for |
|---|---|---|
model-zero | Model Zero | Fast, low-cost reasoning tuned for agent loops, tool calls and high-volume pipelines. |
model-one-flash | Model One Flash | Efficient general-purpose inference for everyday production traffic. |
model-one | Model One | Our larger model for advanced reasoning and long, complex tasks. |
Send the model id in the model field. The same id comes back in every response. Context windows and speeds are not published yet.
Prices

| Model id | Input | Cached input | Output | Bonus credits |

- Input is
prompt_tokensminus the cached part. Cached input isprompt_tokens_details.cached_tokensas the model reports it. When the model reports no cached tokens, the whole prompt is billed as input. - Output is
completion_tokens, which includes reasoning tokens. - The cost of each request is rounded up to the next micro-dollar ($0.000001).
- Bonus credits cannot pay for
model-one. See Bonus credits.
Worked example
A model-zero request with 12,000 prompt tokens, 10,000 of them cached, and 800 output tokens:
input 2,000 × $0.50 / 1M = $0.001000
cached 10,000 × $0.10 / 1M = $0.001000
output 800 × $1.00 / 1M = $0.000800
total $0.002800List models
GET /v1/models returns the models that are currently enabled, sorted by id. It needs a valid key but does not touch your balance.

}There is no GET /v1/models/{id}. A model id that is unknown or disabled answers 404 model_not_found on completion requests.
