Evaluating Conversations

To accurately evaluate interactions within a dialogue, you can use Galtea’s session-based workflow. This approach allows you to log an entire conversation and then run evaluations on all of its turns at once. Certain metrics are specifically designed for conversational analysis and require the full context:

Role Adherence: Measures how well the AI stays within its defined role.
Knowledge Retention: Assesses the model’s ability to remember and use information from previous turns.
Conversation Completeness: Evaluates whether the conversation has reached a natural and informative conclusion.
Conversation Relevancy: Assesses whether each turn in the conversation is relevant to the ongoing topic.

The Session-Based Workflow

Create a Session

A Session acts as a container for all the turns in a single conversation. You create one at the beginning of an interaction.

Log Inference Results

Each user input and model output pair is an Inference Result. You can log these turns individually or in a single batch call after the conversation ends. Using a batch call is more efficient.

Evaluate the Session

Once the session is logged, you can create evaluations for the entire conversation using the evaluations.create() method.

Choose your scenario

Test-based evaluation
Past conversations (offline ingestion)
Monitoring (production)

Use this when you have test cases. It requires test_case_id and is often combined with the Conversation Simulator to generate turns.

# Fetch your test cases (created from a CSV of scenarios)
test_cases = galtea_client.test_cases.list(test_id=scenarios_test.id)
if test_cases is None or len(test_cases) == 0:
    raise ValueError("No test cases found")


# Implement your Agent (connect your product/model)
class MyAgent(galtea.Agent):
    def call(self, input_data: galtea.AgentInput) -> galtea.AgentResponse:
        return galtea.AgentResponse(content="...")


for test_case in test_cases:
    # Create a session linked to the test case
    session = galtea_client.sessions.create(
        version_id=version_id,
        test_case_id=test_case.id,
    )

    # Run the simulator (synthetic user) with your Agent
    galtea_client.simulator.simulate(
        session_id=session.id,
        agent=MyAgent(),
        max_turns=test_case.max_iterations or 20,
    )

    # Evaluate the full conversation
    galtea_client.evaluations.create(
        session_id=session.id,
        metrics=[
            {"name": "Conversation Relevancy"},
            {"name": "Role Adherence"},
            {"name": "Knowledge Retention"},
        ],
    )

See the full workflow in Simulating Conversations.

Use this when the conversation already happened outside Galtea. Ingest the transcript by creating a session (no test_case_id) and logging all turns in a batch, then evaluate.

# Optional: map to your own conversation ID and mark as production if these are real users
session = galtea_client.sessions.create(
    version_id=version_id,
    custom_id="EXTERNAL_CONVERSATION_ID",
    is_production=True,
)

conversation_turns = [
    {"role": "user", "content": "What are some lower-risk investment strategies?"},
    {
        "role": "assistant",
        "content": "For lower-risk investments, consider diversified index funds, bonds, or Treasury securities.",
        "retrieval_context": "Low-risk investment options include index funds, government bonds, and Treasury securities.",
    },
    {"role": "user", "content": "With age, should the investment strategy change?"},
    {
        "role": "assistant",
        "content": "Yes, many advisors recommend shifting to more conservative investments as you approach retirement.",
        "retrieval_context": "Financial advisors typically recommend a more conservative asset allocation as investors near retirement age.",
    },
]

# Log all turns at once
galtea_client.inference_results.create_batch(
    session_id=session.id, conversation_turns=conversation_turns
)

# Evaluate the full session
galtea_client.evaluations.create(
    session_id=session.id,
    metrics=[
        {"name": "Role Adherence"},
        {"name": "Knowledge Retention"},
        {"name": "Conversation Relevancy"},
    ],
)

Use this for real-time logging of user interactions from your live product. Create the session with is_production=True and log turns as they happen (or batch at the end), then evaluate.

Log turns individually
Log turns in a batch

session = galtea_client.sessions.create(
    version_id=version_id,
    is_production=True,
)


def your_product(user_input: str) -> str:
    return f"This is a simulated response to '{user_input}'"


def handle_turn(user_input: str) -> str:
    model_output = your_product(user_input)
    galtea_client.inference_results.create(
        session_id=session.id, input=user_input, output=model_output
    )
    return model_output


# Simulate production interactions
handle_turn("Hello!")
handle_turn("What services do you offer?")

session_batch = galtea_client.sessions.create(
    version_id=version_id,
    is_production=True,
)

conversation_turns = [
    {"role": "user", "content": "What are some lower-risk investment strategies?"},
    {
        "role": "assistant",
        "content": "For lower-risk investments, consider diversified index funds, bonds, or Treasury securities.",
    },
]

galtea_client.inference_results.create_batch(
    session_id=session_batch.id, conversation_turns=conversation_turns
)

# Evaluate when the conversation is complete
galtea_client.evaluations.create(
    session_id=session.id,
    metrics=[{"name": "Conversation Relevancy"}, {"name": "Knowledge Retention"}],
)
