This page goes over some advanced tracing features.

​
Adding a trace name

If you’re tracing multiple functions, you can use the name parameter to distinguish between them:

def ask_question(question="What is the capital of the US?") -> str:
    with baserun.start_trace(name="General knowledge question"):
        # Your code here

Currently, when using python sdk, you can name a trace only when using baserun.start_trace context manager and it’s not possible to do so when using @baserun.trace decorator.

​
Setting a trace’s result

By default a trace’s result value will be the return value of the function or context that is traced. If you want to be more explicit, you can set the result value of a trace.

def ask_question(question="What is the capital of the US?") -> str:
    with baserun.start_trace() as trace:
        # Your code here, for example:
        answer_id = answer_question(question)

        trace.result = my_result

​
Adding custom metadata

You can also add custom metadata. This metadata could be whatever you like, provided that it is JSON serializable. For instance, you may want to include references to other objects or systems.

def ask_question(question="What is the capital of the US?") -> str:
    with baserun.start_trace(name="Answer question") as trace:
        # Make a completion
        completion = client.chat.completions.create(
            model="gpt-4-1106-preview",
            messages=[{"role": "user", "content": question}],
        )

        # Your code here, for example:
        answer_id = persist_answer(question, completion)

        # Add whatever metadata you like
        trace.metadata = {
          "answer_id": answer_id
        }

​
Associating with an LLM request

By default, annotations such as logs and checks are associated with a trace as a whole. To associate a with particular LLM request, you simply need to pass the completion ID from your LLM request. To do so using OpenAI’s SDK, you can do the following:

@baserun.trace
def ask_question(question="What is the capital of the US?") -> str:
    completion = client.chat.completions.create(
        model="gpt-4-1106-preview",
        messages=[{"role": "user", "content": question}],
    )
    # Your code here, for example:
    answer = persist_answer(question, completion)

    # Create the annotation
    annotation = baserun.annotate(completion.id)

    # Capture whatever annotations you need
    annotation.log("Answer", metadata={"answer_id": answer.id})

    # Make sure to submit the annotation
    annotation.submit()

Here is how the user feedback will look like in Baserun dashboard:

​
Example

import baserun
import openai

PROMPT = """As a customer service representative for an online pet product retailer, your main goal is to
provide a positive and informative chat experience for customers..."""

def run_chatbot():
"""A basic chatbot"""
client = openai.OpenAI()
conversation = [{"role": "system", "content": PROMPT}]

    print(f"Start your conversation. Type `exit` to end the conversation.")
    user_input = input(">")
    conversation.append({"role": "user", "content": user_input})

    # Start a trace before your first OpenAI call, giving it a name
    with baserun.start_trace(name="Chatbot CLI loop") as trace:
        # Tracing allows each iteration's LLM calls to be grouped together
        while user_input != "exit":
            completion = client.chat.completions.create(
                model="gpt-4-1106-preview",
                messages=conversation,
            )
            content = completion.choices[0].message.content
            conversation.append({"role": "assistant", "content": content})

            print(content)
            user_input = input(">")
            conversation.append({"role": "user", "content": user_input})

        # Set the trace result for display in the Baserun UI (here it is set to the last content of the conversation)
        trace.result = conversation[-1]["content"]

if **name** == "**main**":
baserun.api_key = YOUR_BASERUN_API_KEY_HERE
openai.api_key = YOUR_OPENAI_API_KEY_HERE
baserun.init()
run_chatbot()
