🛠️ Building your Application

Build your application with complete flexibility

With Palico, you have complete control over the implementation details of your LLM application. Build any application by creating a Chat function.

import { Chat } from '@palico-ai/app';
import OpenAI from 'openai';

// 1. implement the Chat type
const handler: Chat = async ({ userMessage }) => {
  // 2. implement your application logic
  const response = await openai.chat.completions.create({
    model: 'gpt-3.5-turbo-0125',
    messages: [{ role: 'user', content: userMessage }],
  });
  return {
    message: response.choices[0].message.content,
  };
};

// 3. export the handler
export default handler;

🔄 Improve Performance with Experiments

Palico helps you create an iterative loop to systematically improve the performance of your application.

Create Test-Cases

Define test-cases that models the expected behavior of your application

const testCases: TestDatasetFN = async () => {
  return [
    {
      input: { // input to your LLM Application
        userMessage: "What is the capital of France?",
      },
      tags: { // tags to help you categorize your test-cases
        intent: "question",
      },
      metrics: [
        // example metrics
        containsEvalMetric({
          substring: "Paris",
        }),
        levensteinEvalMetric({
          expected: "Paris",
        }),
        rougeSkipBigramSimilarityEvalMetric({
          expected: "Paris",
        }),
      ],
    },
  ];
};
