CreateCompletionRequest class
Constructors
-
CreateCompletionRequest({required String model, CreateCompletionRequestPrompt? prompt, String? suffix, int? maxTokens = 16, num? temperature = 1, num? topP = 1, int? n = 1, bool? stream = false, int? logprobs, bool? echo = false, CreateCompletionRequestStop? stop, num? presencePenalty = 0, num? frequencyPenalty = 0, int? bestOf = 1, Object? logitBias, String? user})
-
Returns a new CreateCompletionRequest instance.
Properties
-
bestOf
↔ int?
-
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 and n specifies how many to return – best_of must be greater than n. 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 and stop.
getter/setter pair
-
echo
↔ bool?
-
Echo back the prompt in addition to the completion
getter/setter pair
-
frequencyPenalty
↔ num?
-
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.
getter/setter pair
-
hashCode
→ int
-
The hash code for this object.
no setteroverride
-
logitBias
↔ Object?
-
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 (which works for both GPT-2 and GPT-3) 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.
getter/setter pair
-
logprobs
↔ int?
-
Include the log probabilities on the
logprobs most likely tokens, as well the chosen tokens. For example, if logprobs is 5, the API will return a list of the 5 most likely tokens. The API will always return the logprob of the sampled token, so there may be up to logprobs+1 elements in the response. The maximum value for logprobs is 5. If you need more than this, please contact us through our Help center and describe your use case.
getter/setter pair
-
maxTokens
↔ int?
-
The maximum number of tokens to generate in the completion. The token count of your prompt plus
max_tokens cannot exceed the model's context length. Most models have a context length of 2048 tokens (except for the newest models, which support 4096).
getter/setter pair
-
model
↔ String
-
ID of the model to use. You can use the List models API to see all of your available models, or see our Model overview for descriptions of them.
getter/setter pair
-
n
↔ int?
-
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 and stop.
getter/setter pair
-
presencePenalty
↔ num?
-
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.
getter/setter pair
-
prompt
↔ CreateCompletionRequestPrompt?
-
getter/setter pair
-
runtimeType
→ Type
-
A representation of the runtime type of the object.
no setterinherited
-
stop
↔ CreateCompletionRequestStop?
-
getter/setter pair
-
stream
↔ bool?
-
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.
getter/setter pair
-
suffix
↔ String?
-
The suffix that comes after a completion of inserted text.
getter/setter pair
-
temperature
↔ num?
-
What sampling temperature to use. Higher values means the model will take more risks. Try 0.9 for more creative applications, and 0 (argmax sampling) for ones with a well-defined answer. We generally recommend altering this or
top_p but not both.
getter/setter pair
-
topP
↔ num?
-
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.
getter/setter pair
-
user
↔ String?
-
A unique identifier representing your end-user, which can help OpenAI to monitor and detect abuse. Learn more.
