Structure Class

InferenceConfiguration dataclass

Specifications about the inference parameters that were provided alongside the prompt. These are specified in the PromptOverrideConfiguration object that was set when the agent was created or updated. For more information, see Inference parameters for foundation models.

Attributes

maximum_length class-attribute instance-attribute
maximum_length: int | None = None

The maximum number of tokens allowed in the generated response.

stop_sequences class-attribute instance-attribute
stop_sequences: list[str] | None = None

A list of stop sequences. A stop sequence is a sequence of characters that causes the model to stop generating the response.

temperature class-attribute instance-attribute
temperature: float | None = None

The likelihood of the model selecting higher-probability options while generating a response. A lower value makes the model more likely to choose higher-probability options, while a higher value makes the model more likely to choose lower-probability options.

top_k class-attribute instance-attribute
top_k: int | None = None

While generating a response, the model determines the probability of the following token at each point of generation. The value that you set for topK is the number of most-likely candidates from which the model chooses the next token in the sequence. For example, if you set topK to 50, the model selects the next token from among the top 50 most likely choices.

top_p class-attribute instance-attribute
top_p: float | None = None

While generating a response, the model determines the probability of the following token at each point of generation. The value that you set for Top P determines the number of most-likely candidates from which the model chooses the next token in the sequence. For example, if you set topP to 0.8, the model only selects the next token from the top 80% of the probability distribution of next tokens.
