Xai lm invoker

Defines a module to interact with xAI language models.

XAILMInvoker(model_name, api_key=None, model_kwargs=None, default_hyperparameters=None, tools=None, response_schema=None, output_analytics=False, retry_config=None, thinking=False, input_transformers=None, output_transformers=None, input_transformer=None, output_transformer=None)

Bases: StreamingBufferMixin, BaseLMInvoker

A language model invoker to interact with xAI language models.

Attributes:

Name	Type	Description
model_id	str	The model ID of the language model.
model_provider	str	The provider of the language model.
model_name	str	The name of the language model.
client_params	dict[str, Any]	The xAI client initialization parameters.
default_config	dict[str, Any]	Default config for invoking the model.
tools	list[Tool]	The list of tools provided to the model to enable tool calling.
response_schema	ResponseSchema | None	The schema of the response. If provided, the model will output a structured response as defined by the schema. Supports both Pydantic BaseModel and JSON schema dictionary.

retry_config	RetryConfig | None	The retry configuration for the language model.
thinking	ThinkingConfig	The thinking configuration for the language model.
image_generation	bool	Whether to enable image generation.
input_transformers	list[InputTransformerConfig]	The list of input transformer configs to use.
output_transformers	list[OutputTransformerConfig]	The list of output transformer configs to use.

Initializes a new instance of the XAILMInvoker class.
