Request

Header Params

Authorization

string

required

Example:

Bearer {{api-key}}

Body Params application/json

model

string

required

ID of the model to be used.For more information on which models are available for the Chat API, see the Model Endpoint Compatibility Table:https://platform.openai.com/docs/models/model-endpoint-compatibility

max_tokens

integer

optional

Maximum number of tokens generated for chat completion. The total length of input tokens and generated tokens is limited by the length of the model context.

messages

array [object {2}]

required

In Chat Format:https://platform.openai.com/docs/guides/text?api-mode=chat Generate a chat completion message.

role

string

optional

role

content

string

optional

temperature

integer

optional

What sampling temperature to use, between 0 and 2. Higher values (e.g. 0.8) will make the output more random, while lower values (e.g. 0.2) will make the output more focused and deterministic. We usually recommend changing this or top_p but not both.

top_p

integer

optional

An alternative to temperature sampling, called kernel sampling, where the model considers the results of markers with top_p probability mass. So 0.1 means that only the markers that make up the top 10% probability mass are considered. We usually recommend changing either this or TEMPERATURE but not both.

integer

optional

How many chat completion options to generate for each input message.

stream

boolean

optional

If set, a partial message increment will be sent, as in ChatGPT. When the token is available, the token will be sent as a data-only server send event data: [DONE] and the stream is terminated by the message. For sample code, see the OpenAI Cookbook.

stop

string

optional

The API will stop generating more tokens for up to 4 sequences.

presence_penalty

number

optional

A number between -2.0 and 2.0. Positive values penalize new tokens based on whether or not they have appeared in the text so far, thus increasing the likelihood that the model will talk about new topics. See more about frequency and presence penalties:https://platform.openai.com/docs/api-reference/parameter-details

frequency_penalty

number

optional

logit_bias

null

optional

Modifies the likelihood that the specified token will appear in the completion. Accepts a json object that maps markers (specified by the marker ID in the tagger) to an associated deviation value from -100 to 100. Mathematically, the deviations are added to the logits generated by the model before sampling. The exact effect varies from model to model, but values between -1 and 1 should reduce or increase the likelihood of selection; values like -100 or 100 should result in prohibited or exclusive selection of the associated token.

user

string

optional

Unique identifiers that represent your end users can help OpenAI monitor and detect abuse. Learn more:https://platform.openai.com/docs/guides/safety-best-practices/end-user-ids
