.prompt string | null | array[string] | array[integer] | array[array] Required
One of: The prompt(s) to generate completions for, encoded as a string, array of strings, array of tokens, or array of token arrays.
Note that <|endoftext|> is the document separator that the model sees during training, so if a prompt is not specified the model will generate as if from the beginning of a new document.
Default value is empty.

Note that <|endoftext|> is the document separator that the model sees during training, so if a prompt is not specified the model will generate as if from the beginning of a new document.
Default value is
<|endoftext|>
.The prompt(s) to generate completions for, encoded as a string, array of strings, array of tokens, or array of token arrays.

best_of integer | null
Generates
best_of
completions server-side and returns the "best" (the one with the highest log probability per token). Results cannot be streamed.When used with
n
,best_of
controls the number of candidate completions andn
specifies how many to return –best_of
must be greater thann
.Note: Because this parameter generates many completions, it can quickly consume your token quota. Use carefully and ensure that you have reasonable settings for
max_tokens
andstop
.Minimum value is
0
, maximum value is20
. Default value is1
. -
echo boolean | null
Echo back the prompt in addition to the completion
Default value is
false
. -
frequency_penalty number | null
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.
See more information about frequency and presence penalties.
Minimum value is
-2
, maximum value is2
. Default value is0
. -
logit_bias object | null
Modify the likelihood of specified tokens appearing in the completion.
Accepts a JSON object that maps tokens (specified by their token ID in the GPT tokenizer) to an associated bias value from -100 to 100. You can use this tokenizer tool to convert text to token IDs. Mathematically, the bias is added to the logits generated by the model prior to sampling. The exact effect will vary per model, but values between -1 and 1 should decrease or increase likelihood of selection; values like -100 or 100 should result in a ban or exclusive selection of the relevant token.
As an example, you can pass
{"50256": -100}
to prevent the <|endoftext|> token from being generated. -
logprobs integer | null
Include the log probabilities on the
logprobs
most likely output tokens, as well the chosen tokens. For example, iflogprobs
is 5, the API will return a list of the 5 most likely tokens. The API will always return thelogprob
of the sampled token, so there may be up tologprobs+1
elements in the response.The maximum value for
logprobs
is 5.Minimum value is
0
, maximum value is5
. -
max_tokens integer | null
The maximum number of tokens that can be generated in the completion.
The token count of your prompt plus
max_tokens
cannot exceed the model's context length. Example Python code for counting tokens.Minimum value is
0
. Default value is16
. -
n integer | null
How many completions to generate for each prompt.
Note: Because this parameter generates many completions, it can quickly consume your token quota. Use carefully and ensure that you have reasonable settings for
max_tokens
andstop
.Minimum value is
1
, maximum value is128
. Default value is1
. -
presence_penalty number | null
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.
See more information about frequency and presence penalties.
Minimum value is
-2
, maximum value is2
. Default value is0
. -
seed integer | 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.Determinism is not guaranteed, and you should refer to the
system_fingerprint
response parameter to monitor changes in the backend.Minimum value is
-9223372036854775808
, maximum value is9223372036854775807
. stop string | null | array[string]
One of: Up to 4 sequences where the API will stop generating further tokens. The returned text will not contain the stop sequence.
Default value is
<|endoftext|>
.Up to 4 sequences where the API will stop generating further tokens. The returned text will not contain the stop sequence.
At least
1
but not more than4
elements.-
stream boolean | null
Whether to stream back partial progress. If set, tokens will be sent as data-only server-sent events as they become available, with the stream terminated by a
data: [DONE]
message. Example Python code.Default value is
false
. -
stream_options object | null
Options for streaming response. Only set this when you set
stream: true
. -
suffix string | null
The suffix that comes after a completion of inserted text.
This parameter is only supported for
gpt-3.5-turbo-instruct
. -
temperature number | null
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.
We generally recommend altering this or
top_p
but not both.Minimum value is
0
, maximum value is2
. Default value is1
. -
top_p number | null
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.
We generally recommend altering this or
temperature
but not both.Minimum value is
0
, maximum value is1
. Default value is1
. -
user string
A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. Learn more.
