OptionalauthenticatorOptionalcacheOptionalcallbackOptionalcallbacksOptionaldisableWhether to disable streaming.
If streaming is bypassed, then stream() will defer to
invoke().
OptionalfrequencyPositive 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.
OptionalheadersOptionalidOptionallogitIncreasing or decreasing probability of tokens being selected during generation; a positive bias makes a token more likely to appear, while a negative bias makes it less likely.
OptionallogprobsWhether to return log probabilities of the output tokens or not. If true, returns the log probabilities of each output token returned in the content of message.
OptionalmaxThe maximum number of tokens that can be generated in the chat completion. The total length of input tokens and generated tokens is limited by the model's context length. Set to 0 for the model's configured max generated tokens.
OptionalmaxThe maximum number of concurrent calls that can be made.
Defaults to Infinity, which means no limit.
OptionalmaxThe maximum number of retries that can be made for a single call, with an exponential backoff between each attempt. Defaults to 6.
OptionalmaxThe maximum number of tokens that can be generated in the chat completion. The total length of input tokens and generated tokens is limited by the model's context length. Set to 0 for the model's configured max generated tokens. This value is now deprecated in favor of maxCompletionTokens. If specified together with maxCompletionTokens, maxTokens will be ignored.
OptionalmessagesThe messages for this chat session.
OptionalmetadataOptionalmodelThe model to use for the chat completion.
Please refer to the list of models.
OptionalnHow many chat completion choices to generate for each input message. Note that you will be charged based on the number of generated tokens across all of the choices. Keep n as 1 to minimize costs.
OptionalonCustom handler to handle failed attempts. Takes the originally thrown error object as input, and should itself throw an error if the input error is not retryable.
OptionalpresencePositive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics.
OptionalprojectThe project that contains the resource. Either space_id or project_id has to be given.
OptionalresponseThe chat response format parameters.
OptionalseedRandom number generator seed to use in sampling mode for experimental repeatability.
OptionalsignalOptionalspaceThe space that contains the resource. Either space_id or project_id has to be given.
OptionalstopStop sequences are one or more strings which will cause the text generation to stop if/when they are produced as part of the output. Stop sequences encountered prior to the minimum number of tokens being generated will be ignored.
OptionalstreamingOptionaltagsOptionaltemperatureWhat sampling temperature to use,. 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.
OptionaltimeTime limit in milliseconds - if not completed within this time, generation will stop. The text generated so far will be returned along with the `TIME_LIMIT`` stop reason. Depending on the users plan, and on the model being used, there may be an enforced maximum time limit.
OptionaltoolSpecifying a particular tool via {"type": "function", "function": {"name": "my_function"}} forces the
model to call that tool.
Only one of tool_choice_option or tool_choice must be present.
OptionaltoolUsing none means the model will not call any tool and instead generates a message.
The following options (auto and required) are not yet supported.
Using auto means the model can pick between generating a message or calling one or more tools. Using
required means the model must call one or more tools.
Only one of tool_choice_option or tool_choice must be present.
OptionaltoolsTool functions that can be called with the response.
OptionaltopAn integer specifying the number of most likely tokens to return at each token position, each with an
associated log probability. The option logprobs must be set to true if this parameter is used.
OptionaltopPAn 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.
