Overview of BenchLLM

What is BenchLLM?

BenchLLM is a tool designed to evaluate the performance and quality of applications powered by Large Language Models (LLMs). It provides a flexible and comprehensive framework for building test suites, generating quality reports, and monitoring model performance. Whether you need automated, interactive, or custom evaluation strategies, BenchLLM offers the features and capabilities to ensure your AI models meet the required standards.

How does BenchLLM work?

BenchLLM works by allowing users to define tests, run models against those tests, and then evaluate the results. Here’s a detailed breakdown:

  1. Define Tests Intuitively: Tests can be defined in JSON or YAML format, making it easy to set up and manage test cases.
  2. Organize Tests into Suites: Organize tests into suites for easy versioning and management. This helps in maintaining different versions of tests as the models evolve.
  3. Run Tests: Use the powerful CLI or flexible API to run tests against your models. BenchLLM supports OpenAI, Langchain, and any other API out of the box.
  4. Evaluate Results: BenchLLM provides multiple evaluation strategies to assess the performance of your models. It helps identify regressions in production and monitor model performance over time.
  5. Generate Reports: Generate evaluation reports and share them with your team. These reports provide insights into the strengths and weaknesses of your models.

Example Code Snippets:

Here’s an example of how to use BenchLLM with Langchain:

from benchllm import SemanticEvaluator, Test, Tester
from langchain.agents import AgentType, initialize_agent
from langchain.llms import OpenAI

## Keep your code organized in the way you like
def run_agent(input: str):
    llm=OpenAI(temperature=0)
    agent = initialize_agent(
        load_tools(["serpapi", "llm-math"], llm=llm),
        llm=llm,
        agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION
    )
    return agent(input)["output"]

## Instantiate your Test objects
tests = [
    Test(
        input="When was V7 founded? Divide it by 2",
        expected=["1009", "That would be 2018 / 2 = 1009"]
    )
]

## Use a Tester object to generate predictions
tester = Tester(run_agent)
tester.add_tests(tests)
predictions = tester.run()

## Use an Evaluator object to evaluate your model
evaluator = SemanticEvaluator(model="gpt-3")
evaluator.load(predictions)
evaluator.run()

Here’s an example of how to use BenchLLM with OpenAI’s ChatCompletion API:

import benchllm
from benchllm.input_types import ChatInput
import openai

def chat(messages: ChatInput):
    response = openai.ChatCompletion.create(
        model="gpt-3.5-turbo",
        messages=messages
    )
    return response.choices[0].message.content.strip()

@benchllm.test(suite=".")
def run(input: ChatInput):
    return chat(input)
