Score Configs

Define validation rules for scores (ranges, categories, descriptions).

​
Create and Use Score Configs

import os
import time
from upsonic import Agent, Task
from upsonic.integrations.langfuse import Langfuse

langfuse = Langfuse()
agent = Agent("anthropic/claude-sonnet-4-6", instrument=langfuse)

# Create configs
numeric_config = langfuse.create_score_config(
    "quality", "NUMERIC",
    min_value=0, max_value=1,
    description="Overall quality score between 0 and 1",
)
print(f"Numeric config ID: {numeric_config['id']}")

categorical_config = langfuse.create_score_config(
    "sentiment", "CATEGORICAL",
    categories=[
        {"label": "positive", "value": 1},
        {"label": "neutral", "value": 0},
        {"label": "negative", "value": -1},
    ],
)
print(f"Categorical config ID: {categorical_config['id']}")

boolean_config = langfuse.create_score_config("factual", "BOOLEAN")
print(f"Boolean config ID: {boolean_config['id']}")

# Run agent and score with config validation
result = agent.do("What is 2 + 2?", return_output=True)
trace_id = result.trace_id
time.sleep(8)

validated_score = langfuse.score(trace_id, "quality", 0.8, config_id=numeric_config["id"])
print(f"Validated score: {validated_score}")

langfuse.shutdown()

​
List, Get, Update Configs

import os
from upsonic.integrations.langfuse import Langfuse

langfuse = Langfuse()

# List all configs
all_configs = langfuse.get_score_configs()
print(f"Total configs: {all_configs['meta']['totalItems']}")

# Get a single config by ID
if all_configs["data"]:
    config_id = all_configs["data"][0]["id"]
    config = langfuse.get_score_config(config_id)
    print(f"Config: {config['name']} ({config['dataType']})")

    # Update config
    updated = langfuse.update_score_config(
        config_id,
        description="Updated description",
    )
    print(f"Updated: {updated['description']}")

    # Archive
    langfuse.update_score_config(config_id, is_archived=True)
    print("Archived")

    # Unarchive
    langfuse.update_score_config(config_id, is_archived=False)
    print("Unarchived")

langfuse.shutdown()
