Get Started with a few lines of code:

pip install lastmile

from lastmile.lib.auto_eval import AutoEval, BuiltinMetrics
import pandas as pd


client = AutoEval()
result = client.evaluate_data(
    data=pd.DataFrame({
        "input": ["Where did the author grow up?"],
        "output": ["France"],
        "ground_truth": ["England"]
    }),
    metrics=[BuiltinMetrics.FAITHFULNESS]
)
yarn add lastmile

import AutoEval, { BuiltinMetrics } from "lastmile/lib/auto_eval";


const client = await AutoEval.create();
const result = await client.evaluateData({
  data: [
    {
      input: "Where did the author grow up?",
      output: "France",
      ground_truth: "England",
    },
  ],
  metrics: [BuiltinMetrics.FAITHFULNESS]
});

Comprehensive Evaluation Platform for Reliable, Real-World AI Systems

From synthetic data creation to fine-tuning & fast inference, LastMile AI offers a comprehensive toolkit to evaluate your AI application's performance and ensure its success in real-world scenarios

01

Deploy AI Securely, On Your Terms

Deploy AutoEval within your own Private Virtual Cloud environment and retain complete control over your data, infrastructure, and security protocols and meet stringent compliance requirements.
02

Goodbye Manual Labeling: Hello Synthetic Data

Train robust, private AI evaluation models faster with diverse, high-quality labels. AutoEval automates labeling and cut costs with synthetic data generation.
03

Stop Guessing, Start Knowing: Fine-Tune Evaluation Models

Standard evaluation metrics are a starting point, but they often fail to capture the nuances of your AI use-case. Train custom evaluation models specifically tailored to your app's' data distribution.
04
