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_transformer=InputTransformerType.IDENTITY, output_transformer=OutputTransformerType.IDENTITY)

Bases: StreamingBufferMixin, BaseLMInvoker

A language model invoker to interact with xAI language models.

Examples:

lm_invoker = XAILMInvoker(model_name="grok-4-fast-non-reasoning")
result = await lm_invoker.invoke("Hi there!")

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.

output_analytics bool

Whether to output the invocation analytics.

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_transformer InputTransformerType

The type of input transformer to use.

output_transformer OutputTransformerType

The type of output transformer to use.

Initializes a new instance of the XAILMInvoker class.

Parameters:

Name Type Description Default
model_name str

The name of the xAI model.

required
api_key str | None

The API key for authenticating with xAI. Defaults to None, in which case the XAI_API_KEY environment variable will be used.

None
model_kwargs dict[str, Any] | None

Additional model parameters. Defaults to None.

None
default_hyperparameters dict[str, Any] | None

Default hyperparameters for invoking the model. Defaults to None.

None
tools list[LMTool] | None

Tools provided to the language model to enable tool calling. Defaults to None.

None
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. Defaults to None.

None
output_analytics bool

Whether to output the invocation analytics. Defaults to False.

False
retry_config RetryConfig | None

The retry configuration for the language model. Defaults to None, in which case a default config with no retry and 30.0 seconds timeout is used.

None
thinking bool | ThinkingConfig

A boolean or ThinkingConfig object to configure thinking. Defaults to False.

False
input_transformer InputTransformerType

The type of input transformer to use. Defaults to InputTransformerType.IDENTITY, which returns the input without transformation.

IDENTITY
output_transformer OutputTransformerType

The type of output transformer to use. Defaults to OutputTransformerType.IDENTITY, which returns the output without transformation.

IDENTITY

file cached property

The file operations for the language model.

Returns:
