Lighthouz AI Python SDK

Website | Installation | Quick Usage | Documentation

Lighthouz AI is a AI benchmark data generation, evaluation, and security platform. It is meticulously designed to aid developers in both evaluating the reliability and enhancing the capabilities of their Language Learning Model (LLM) applications.

Key Features

Lighthouz has the following features:

1. AutoBench: Create AI-assisted custom benchmarks for security, privacy, and reliability

• Create Benchmarks: AutoBench creates application-specific and task-specific benchmark test cases to assess critical security, privacy, and reliability aspects of your LLM app.
• Flexibility: Tailor-made benchmarks to suit your specific evaluation needs.
• Integration with your own benchmarks: Seamlessly upload and incorporate your pre-existing benchmarks.

2. Eval Studio: Evaluate LLM Applications for security, privacy, and reliability

• Comprehensive Analysis: Thoroughly assess your LLM application for hallucinations, toxicity, out-of-context responses, PII data leaks, and prompt injections.
• Insightful Feedback: Gain valuable insights to refine your application.
• Comparative Analysis: Effortlessly compare different LLM apps and versions.
• Customization: Test the impact on performance of prompts, LLMs, hyperparameters, etc.

Installation

pip install lighthouz

Quick Usage

Initialization

from lighthouz import Lighthouz

LH = Lighthouz("lighthouz_api_key")  # replace with your lighthouz api key

AutoBench: Create custom benchmarks

To generate a benchmark, use the generate_benchmark function under the Benchmark class.

This generates and stores a benchmark spanning benchmark_category categories. The benchmark is a collection of unit tests, called Prompt Unit Tests. Each unit test contains an input prompt, an expected response (if applicable), context (if applicable), and corresponding file name (if applicable).

from lighthouz.benchmark import Benchmark

lh_benchmark = Benchmark(LH)  # LH: Lighthouz instance initialized with Lighthouz API key
benchmark_data = lh_benchmark.generate_benchmark(
    file_path="pdf_file_path",
    benchmark_categories=["rag_benchmark", "out_of_context", "prompt_injection", "pii_leak"]
)
benchmark_id = benchmark_data.get("benchmark_id")
print(benchmark_id)

The possible benchmark_categories options are:

• "rag_benchmark": this creates two hallucination benchmarks, namely Hallucination: direct questions and Hallucination: indirect questions.
• "out_of_context": this benchmark contains out-of-context prompts to test whether the LLM app responds to irrelevant queries.
• "prompt_injection": this benchmark contains prompt injection prompts testing whether the LLM behavior can be manipulated.
• "pii_leak": this benchmark contains prompts testing whether the LLM can leak PII data.

The resulting data, when viewed on Lighthouz platform, looks as follows:

Evaluate a RAG Application on a Benchmark Dataset

The following shows how to use the Evaluation class from Lighthouz to evaluate a RAG system. It involves initializing an evaluation instance with a Lighthouz API key and using the evaluate_rag_model method with a response function, benchmark ID, and app ID.

from lighthouz.evaluation import Evaluation

evaluation = Evaluation(LH)  # LH: Lighthouz instance initialized with Lighthouz API key
e_single = evaluation.evaluate_rag_model(
    response_function=llamaindex_rag_query_function,
    benchmark_id="lighthouz_benchmark_id",  # replace with benchmark id
    app_id="lighthouz_app_id",  # replace with the app id
)
print(e_single)

The evaluation results, when viewed on Lighthouz platform, look as follows:
