Authorizations

Authorization
string
header
required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

application/json
model
string
required

ID of the model to use

prompt
string
required

The prompt(s) to generate completions for, encoded as a string, array of strings, array of tokens, or array of token arrays.

echo
boolean | null
default:false

Echo back the prompt in addition to the completion

frequency_penalty
number | null
default:0

Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim.

max_tokens
number | null
default:16

The maximum number of tokens that can be generated in the completion.

presence_penalty
number | null
default:0

Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics.

Required range: -2 <= x <= 2
seed
number | null

If specified, our system will make a best effort to sample deterministically, such that repeated requests with the same seed and parameters should return the same result.

stop

Up to 4 sequences where the API will stop generating further tokens. The returned text will not contain the stop sequence.

temperature
number | null
default:1

What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.

top_p
number | null
default:1

An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.

user
string

A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse.

orq
object

Leverage Orq's intelligent routing capabilities to enhance your AI application with enterprise-grade reliability and observability. Orq provides automatic request management including retries on failures, model fallbacks for high availability, contact-level analytics tracking, conversation threading, and dynamic prompt templating with variable substitution.

  ],
  "timeout": { "call_timeout": 30000 }
}
stream
boolean
default:false

Response

Represents a completion response from the API.

id
string
required

A unique identifier for the completion.

choices
object[]
required

The list of completion choices the model generated for the input prompt.

model
string
required

The model used for the chat completion.

object
string
required

The object type

created

The Unix timestamp (in seconds) of when the chat completion was created.

system_fingerprint
string

This fingerprint represents the backend configuration that the model runs with.

usage
object

Usage statistics for the completion request.
