Installation

npm install --save node-llama-cpp

This package comes with pre-built binaries for macOS, Linux and Windows.

If binaries are not available for your platform, it'll fallback to download the latest version of llama.cpp and build it from source with cmake. To disable this behavior set the environment variable NODE_LLAMA_CPP_SKIP_DOWNLOAD to true.

Usage

import {fileURLToPath} from "url";
import path from "path";
import {LlamaModel, LlamaContext, LlamaChatSession} from "node-llama-cpp";

const __dirname = path.dirname(fileURLToPath(import.meta.url));

const model = new LlamaModel({
    modelPath: path.join(__dirname, "models", "codellama-13b.Q3_K_M.gguf")
});
const context = new LlamaContext({model});
const session = new LlamaChatSession({context});


const q1 = "Hi there, how are you?";
console.log("User: " + q1);

const a1 = await session.prompt(q1);
console.log("AI: " + a1);


const q2 = "Summerize what you said";
console.log("User: " + q2);

const a2 = await session.prompt(q2);
console.log("AI: " + a2);
