Examples
from langfuse.scores import CreateScoreRequest
CreateScoreRequest( name="novelty", value=0.9, trace_id="cdef-1234-5678-90ab", )
The value of the score. Must be passed as string for categorical and text scores, and numeric for boolean and numeric scores. Boolean score values must equal either 1 or 0 (true or false). Text score values must be between 1 and 500 characters.
The environment of the score. Can be any lowercase alphanumeric string with hyphens and underscores that does not start with 'langfuse'.
The annotation queue referenced by the score. Indicates if score was initially created while processing annotation queue.
The data type of the score. When passing a configId this field is inferred. Otherwise, this field must be passed or will default to numeric.
Reference a score config on a score. The unique langfuse identifier of a score config. When passing this field, the dataType and stringValue fields are automatically populated.
The source of the score. Defaults to API. Set to ANNOTATION to prefill scores (e.g. from an LLM) for a human reviewer to verify in an annotation queue. When source is ANNOTATION, a configId is required unless dataType is CORRECTION. EVAL is reserved for internal evaluator outputs and is not accepted on this endpoint.
!!! abstract "Usage Documentation" Models
A base class for creating Pydantic models.
Attributes:
- __class_vars__: The names of the class variables defined on the model.
- __private_attributes__: Metadata about the private attributes of the model.
- __signature__: The synthesized
__init__[Signature][inspect.Signature] of the model. - __pydantic_complete__: Whether model building is completed, or if there are still undefined fields.
- __pydantic_core_schema__: The core schema of the model.
- __pydantic_custom_init__: Whether the model has a custom
__init__function. - __pydantic_decorators__: Metadata containing the decorators defined on the model.
This replaces
Model.__validators__andModel.__root_validators__from Pydantic V1. - __pydantic_generic_metadata__: Metadata for generic models; contains data used for a similar purpose to __args__, __origin__, __parameters__ in typing-module generics. May eventually be replaced by these.
- __pydantic_parent_namespace__: Parent namespace of the model, used for automatic rebuilding of models.
- __pydantic_post_init__: The name of the post-init method for the model, if defined.
- __pydantic_root_model__: Whether the model is a [
RootModel][pydantic.root_model.RootModel]. - __pydantic_serializer__: The
pydantic-coreSchemaSerializerused to dump instances of the model. - __pydantic_validator__: The
pydantic-coreSchemaValidatorused to validate instances of the model. - __pydantic_fields__: A dictionary of field names and their corresponding [
FieldInfo][pydantic.fields.FieldInfo] objects. - __pydantic_computed_fields__: A dictionary of computed field names and their corresponding [
ComputedFieldInfo][pydantic.fields.ComputedFieldInfo] objects. - __pydantic_extra__: A dictionary containing extra values, if [
extra][pydantic.config.ConfigDict.extra] is set to'allow'. - __pydantic_fields_set__: The names of fields explicitly set during instantiation.
- __pydantic_private__: Values of private attributes set on the model instance.
Source values accepted when creating a score via the public REST API. EVAL is reserved for internal evaluator outputs and is intentionally not exposed here — use commons.ScoreSource when reading scores.
