Here’s a minimal example to get you started with experiments in HoneyHive:

Sample eval script

from honeyhive import evaluate, evaluator
import os
from openai import OpenAI
import random

openai_client = OpenAI(api_key=os.environ["OPENAI_API_KEY"])

# Create function to be evaluated
# inputs -> parameter to which datapoint or json value will be passed
# (optional) ground_truths -> ground truth value for the input
def function_to_evaluate(inputs, ground_truths):
    completion = openai_client.chat.completions.create(
        model="gpt-4o",
        messages=[
            {"role": "system", "content": f"You are an expert analyst specializing in {inputs['product_type']} market trends."},
            {"role": "user", "content": f"Could you provide an analysis of the current market performance and consumer reception of {inputs['product_type']} in {inputs['region']}? Please include any notable trends or challenges specific to this region."}
        ]
    )

    # Output -> session output
    return completion.choices[0].message.content

    )

Running an experiment

Prerequisites

You have already created a project in HoneyHive, as explained here.
You have an API key for your project, as explained here.

Expected Time: 5 minutesSteps

Setup input data

Let’s create our dataset by inputting data directly into our code using a list of JSON objects:

dataset = [
    {
        "inputs": {
            "product_type": "electric vehicles",
            "region": "western europe"   
        },
        "ground_truths": {
            "response": "As of 2023, the electric vehicle (EV) ... ",
        }
    },
    {
        "inputs": {
            "product_type": "gaming consoles",
            "region": "north america"
        },
        "ground_truths": {
            "response": "As of 2023, the gaming console market ... ",
        }
    },
    {
        "inputs": {
            "product_type": "smart home devices",
            "region": "australia and new zealand" 
        },
        "ground_truths": {
            "response": "As of 2023, the market for smart home devices in Australia and New Zealand ... ",
        }
    },
]

The inputs and ground_truths fields will be accessible in both the function we want to evaluate and the evaluator function, as we will see below.

Define the function you want to evaluate

Define the function you want to evaluate. This can be arbitrarily complex, anywhere from a prompt or a simple retrieval pipeline, to an end-to-end multi-agent system:

# inputs -> parameter to which datapoint or json value will be passed
# (optional) ground_truths -> ground truth values for the input
def function_to_evaluate(inputs, ground_truths):

    # Code here

    return result

Important Note About ParametersThe function parameters are positional arguments and must be specified in this order:

inputs (first parameter): dictionary of parameters from your dataset
ground_truths (second parameter): optional ground truth dictionary

The value returned by the function would map to the outputs field of each trace in the experiment and will be accessible to your evaluator function, as we will see below.

(Optional) Setup Evaluators

Define client-side evaluators in your code that run immediately after each experiment iteration. These evaluators have direct access to inputs, outputs, and ground truths, and run synchronously with your experiment.

@evaluator()
def sample_evaluator(outputs, inputs, ground_truths):
    # Code here
    import random
    return random.randint(1, 5)

Important Note About Evaluator ParametersThe evaluator parameters are positional arguments and must be specified in this order:

outputs (first parameter): the output returned by the evaluated function
inputs (second parameter): the original input dictionary
ground_truths (third parameter): the ground truth dictionary

For more complex multi-step pipelines, you can compute and log client-side evaluators on specific traces and spans directly in your experiment harness.

Run experiment

Finally, you can run your experiment with evaluate:

from honeyhive import evaluate
from your_module import function_to_evaluate

if __name__ == "__main__":
    evaluate(
        function = function_to_evaluate,
        api_key = '<HONEYHIVE_API_KEY>',
        project = '<HONEYHIVE_PROJECT>',
        name = 'Sample Experiment',
        # To be passed for datasets managed in code
        dataset = dataset,
        # Add evaluators to your trace at the end of each execution
        evaluators=[sample_evaluator, ...],
        server_url='<HONEYHIVE_SERVER_URL>'  # Optional / Required for self-hosted or dedicated deployments
    )

If you are using a self-hosted or dedicated deployment, you also need to pass:

server_url: The private HoneyHive endpoint found in the Settings page in the HoneyHive app.

Dashboard View

Remember to review the results in your HoneyHive dashboard to gain insights into your model’s performance across different inputs. The dashboard provides a comprehensive view of the experiment results and performance across multiple runs.

Conclusion

By following these steps, you can set up and run experiments using HoneyHive. This allows you to systematically test your LLM-based systems across various scenarios and collect performance data for analysis.

Introduction to Evaluators

Learn how to evaluate and monitor your AI applications with HoneyHive’s flexible evaluation framework.

Comparing Experiments

Compare experiments side-by-side in HoneyHive to identify improvements, regressions, and optimize your workflows.

Running Experiments with HoneyHive's managed datasets

Run experiments using HoneyHive’s managed datasets, enabling centralized dataset management and version control.

Running Experiments with HoneyHive's server-side evaluators

Server-side evaluators are centralized, scalable, and versioned, making them ideal for resource-intensive or asynchronous tasks.

Full code

Here’s a minimal example to get you started with experiments in HoneyHive:

Sample eval script

import { evaluate } from "honeyhive";
import { OpenAI } from 'openai';
const openai = new OpenAI({ apiKey: process.env.OPENAI_KEY });

// Create function to be evaluated
// input -> parameter to which datapoint or json value will be passed
// ground_truths -> optional parameter - ground truth value
export async function functionToEvaluate(input: Record<string, any>, ground_truths: Record<string, any>) {
    
    try {
        const response = await openai.chat.completions.create({
            model: "gpt-4",
            messages: [
                {
                    role: 'system',
                    content: `You are an expert analyst specializing in ${input.product_type} market trends.`
                },
                {
                    role: 'user',
                    content: `Could you provide an analysis of the current market performance and consumer reception of ${input.product_type} in ${input.region}? Please include any notable trends or challenges specific to this region.`
                }
            ],
        });

        // Output -> session output
        return response.choices[0].message;
    } catch (error) {
        console.error('Error making GPT-4 call:', error);
        throw error;
    }
}

const dataset = [
    {
        "inputs": {
            "product_type": "electric vehicles",
            "region": "western europe"   
        },
        "ground_truths": {
            "response": "As of 2023, the electric vehicle (EV) ... ",
        }
    },
    {
        "inputs": {
            "product_type": "gaming consoles",
            "region": "north america"
        },
        "ground_truths": {
            "response": "As of 2023, the gaming console market ... ",
        }
    },
    {
        "inputs": {
            "product_type": "smart home devices",
            "region": "australia and new zealand" 
        },
        "ground_truths": {
            "response": "As of 2023, the market for smart home devices in Australia and New Zealand ... ",
        }
    }
]

// Sample evaluator that returns fixed metrics
function sampleEvaluator(outputs: any, inputs: Record<string, any>, ground_truths: Record<string, any>) {
    // Code here
    return {
        sample_metric: 0.5,
        sample_metric_2: true
    };
}

evaluate({
    function: functionToEvaluate,       // Function to be evaluated
    apiKey: '<HONEYHIVE_API_KEY>',
    project: '<HONEYHIVE_PROJECT>',
    name: 'Sample Experiment',
    dataset: dataset,                        // to be passed for json_list
    evaluators: [sampleEvaluator],                 // to compute client-side metrics on each run
    serverUrl: '<HONEYHIVE_SERVER_URL>'  // Optional / Required for self-hosted or dedicated deployments
})

    },
    {
        "inputs": {

            "response": "As of 2023, the market for smart home devices in Australia and New Zealand ... ",
        }
    }
]

The input fields in the dataset should map to the fields mapped in the evaluate function.

Create the flow you want to evaluate

Define the function you want to evaluate in your experiment:

    // Create function to be evaluated
    export async function functionToEvaluate(input: Record<string, any>, ground_truths: Record<string, any>) {
        try {
            // your code here

            return result;
        } catch (error) {
            console.error('Error:', error);
            throw error;
        }
    }        

Important Note About ParametersThe function parameters are positional arguments and must be specified in this order:

inputs (first parameter): dictionary of parameters from your dataset
ground_truths (second parameter): optional ground truth dictionary

The value returned by the function would map to the outputs field of each run in the experiment.

(Optional) Setup Evaluators

// input -> input defined above
// output -> output returned by the function
function sampleEvaluator(outputs: any, inputs: Record<string, any>, ground_truths: Record<string, any>) {
    // Code here
    // Each evaluator can return a dictionary of metrics
    return { sample_metric: 0.5, sample_metric_2: true };
}

Important Note About Evaluator ParametersThe evaluator parameters are positional arguments and must be specified in this order:

outputs (first parameter): the output returned by the evaluated function
inputs (second parameter): the original input dictionary
ground_truths (third parameter): the ground truth dictionary

For more complex multi-step pipelines, you can compute and log client-side evaluators on specific traces and spans directly in your experiment harness.

Run experiment

import { evaluate } from "honeyhive";
import { functionToEvaluate } from "./your-module";

evaluate({
    function: functionToEvaluate,  // Direct reference since signature matches
    apiKey: '<HONEYHIVE_API_KEY>',
    project: '<HONEYHIVE_PROJECT>',
    name: 'Sample Experiment',
    dataset: dataset,            // to be passed for json_list
    evaluators: [sampleEvaluator],     // Add evaluators to run at the end of each run
    serverUrl: '<HONEYHIVE_SERVER_URL>'  // Optional / Required for self-hosted or dedicated deployments
})

If you are using a self-hosted or dedicated deployment, you also need to pass:

server_url: The private HoneyHive endpoint found in the Settings page in the HoneyHive app.
