pip install giskard

Requires Python 3.12+.

Giskard is an open-source Python library for testing and evaluating agentic systems. The v3 architecture is a modular set of focused packages — each carrying only the dependencies it needs — built from scratch to wrap anything: an LLM, a black-box agent, or a multi-step pipeline.

pip install giskard-checks

Giskard Checks is a lightweight library for creating evaluations (evals) that test LLM-based systems — from simple assertions to LLM-as-judge assessments. Unlike traditional unit tests, evals are designed for non-deterministic outputs where the same input can produce different valid responses.

Use Giskard Checks to:

• Catch regressions — verify your system still behaves correctly after changes
• Validate RAG quality — check if answers are grounded in retrieved context
• Enforce safety rules — ensure outputs conform to your content policies
• Evaluate multi-turn agents — test full conversations, not just single exchanges

Built-in evals include string matching, comparisons, regex, semantic similarity, and LLM-as-judge checks (Groundedness, Conformity, LLMJudge).

from openai import OpenAI
from giskard.checks import Scenario, Groundedness

client = OpenAI()

def get_answer(inputs: str) -> str:
    response = client.chat.completions.create(
        model="gpt-5-mini",
        messages=[{"role": "user", "content": inputs}],
    )
    return response.choices[0].message.content

scenario = (
    Scenario("test_dynamic_output")
    .interact(
        inputs="What is the capital of France?",
        outputs=get_answer,
    )
    .check(
        Groundedness(
            name="answer is grounded",
            answer_key="trace.last.outputs",
            context="France is a country in Western Europe. Its capital is Paris.",
        )
    )
)

result = await scenario.run()
result.print_report()

The run() method is async. In a script, wrap it with asyncio.run(). See the full docs for Suites, LLMJudge, multi-turn scenarios, and more.

Giskard v2 included Scan (automatic vulnerability detection) and RAGET (RAG evaluation test set generation) for both ML models and LLM applications. These features are not available in v3.

pip install "giskard[llm]>2,<3"

Wrap your model and run the scan:

import giskard
import pandas as pd

# Replace my_llm_chain with your actual LLM chain or model inference logic
def model_predict(df: pd.DataFrame):
    """The function takes a DataFrame and must return a list of outputs (one per row)."""
    return [my_llm_chain.run({"query": question}) for question in df["question"]]

giskard_model = giskard.Model(
    model=model_predict,
    model_type="text_generation",
    name="My LLM Application",
    description="A question answering assistant",
    feature_names=["question"],
)

scan_results = giskard.scan(giskard_model)
display(scan_results)

Automatically generate questions, reference answers, and context from your knowledge base:

import pandas as pd
from giskard.rag import generate_testset, KnowledgeBase

# Load your knowledge base documents
df = pd.read_csv("path/to/your/knowledge_base.csv")
knowledge_base = KnowledgeBase.from_pandas(df, columns=["column_1", "column_2"])

testset = generate_testset(
    knowledge_base,
    num_questions=60,
    language='en',
    agent_description="A customer support chatbot for company X",
)
