Simple Chatbot

This is a simple chatbot using Genkit's non-persistent Chat interface.

You can customize the system instructions, and responses are streamed. History is stored in-memory and passed to the server each time.

Things to Try

  • Send a message like "tell me a story"
  • Reset the conversation
  • Set the system message to Talk like a pirate.

Source Code

// api/route.ts

import { z } from "genkit";
// this example requires beta features
import { genkit } from "genkit/beta";

import { googleAI, gemini20Flash } from "@genkit-ai/googleai";

const ai = genkit({
  plugins: [googleAI()], // set the GOOGLE_API_KEY env variable
  model: gemini20Flash,
});

import genkitEndpoint from "@/lib/genkit-endpoint";

export const POST = genkitEndpoint(({ system, messages, prompt }) => {
  const chat = ai.chat({ messages, system });
  return chat.sendStream({ prompt });
});
