class ChatGPTConfig:

|
r"""Defines the parameters for generating chat completions using the
|
|
OpenAI API.
|
|
|
|
Args:
|
|
temperature (float, optional): Sampling temperature to use, between
|
|
:obj:`0` and :obj:`2`. Higher values make the output more random,
|
|
while lower values make it more focused and deterministic.
|
|
(default: :obj:`0.2`)
|
|
top_p (float, optional): An alternative to sampling with temperature,
|
|
called nucleus sampling, where the model considers the results of
|
|
the tokens with top_p probability mass. So :obj:`0.1` means only
|
|
the tokens comprising the top 10% probability mass are considered.
|
|
(default: :obj:`1.0`)
|
|
n (int, optional): How many chat completion choices to generate for
|
|
each input message. ()default: :obj:`1`)
|
|
stream (bool, optional): If True, partial message deltas will be sent
|
|
as data-only server-sent events as they become available.
|
|
(default: :obj:`False`)
|
|
stop (str or list, optional): Up to :obj:`4` sequences where the API
|
|
will stop generating further tokens. (default: :obj:`None`)
|
|
max_tokens (int, optional): The maximum number of tokens to generate
|
|
in the chat completion. The total length of input tokens and
|
|
generated tokens is limited by the model's context length.
|
|
(default: :obj:`None`)
|
|
presence_penalty (float, optional): Number between :obj:`-2.0` and
|
|
:obj:`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. (default: :obj:`0.0`)
|
|
frequency_penalty (float, optional): Number between :obj:`-2.0` and
|
|
:obj:`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. (default: :obj:`0.0`)
|
|
logit_bias (dict, optional): Modify the likelihood of specified tokens
|
|
appearing in the completion. Accepts a json object that maps tokens
|
|
(specified by their token ID in the tokenizer) to an associated
|
|
bias value from :obj:`-100` to :obj:`100`. 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:obj:` -1`
|
|
and :obj:`1` should decrease or increase likelihood of selection;
|
|
values like :obj:`-100` or :obj:`100` should result in a ban or
|
|
exclusive selection of the relevant token. (default: :obj:`{}`)
|
|
user (str, optional): A unique identifier representing your end-user,
|
|
which can help OpenAI to monitor and detect abuse.
|
|
(default: :obj:`""`)
|
|
