Langfuse

Mirascope provides out-of-the-box integration with Langfuse.

You can install the necessary packages directly or using the langfuse extras flag:

pip install "mirascope[langfuse]"

pip install "mirascope[langfuse]"

You can then use the with_langfuse decorator to automatically log calls:

from mirascope import llm
from mirascope.integrations.langfuse import with_langfuse 


@with_langfuse() 
@llm.call(provider="openai", model="gpt-4o-mini")
def recommend_book(genre: str) -> str:
    return f"Recommend a {genre} book."


print(recommend_book("fantasy"))

from mirascope import llm
from mirascope.integrations.langfuse import with_langfuse 


@with_langfuse() 
@llm.call(provider="openai", model="gpt-4o-mini")
def recommend_book(genre: str) -> str:
    return f"Recommend a {genre} book."


print(recommend_book("fantasy"))

This will give you:

• A trace around the recommend_book function that captures items like the prompt template, and input/output attributes and more.
• Human-readable display of the conversation with the agent
• Details of the response, including the number of tokens used
