picoLLM Inference Engine Node.js Binding

Made in Vancouver, Canada by Picovoice

picoLLM Inference Engine

picoLLM Inference Engine is a highly accurate and cross-platform SDK optimized for running compressed large language models. picoLLM Inference Engine is:

• Accurate; picoLLM Compression improves GPTQ by significant margins
• Private; LLM inference runs 100% locally.
• Cross-Platform
• Runs on CPU and GPU
• Free for open-weight models

Compatibility

• Node.js 16+
• Runs on Linux (x86_64), macOS (arm64, x86_64), Windows (x86_64), and Raspberry Pi (5 and 4).

Installation

Using Yarn:

yarn add @picovoice/picollm-node

or using npm:

npm install --save @picovoice/picollm-node

AccessKey

AccessKey is your authentication and authorization token for deploying Picovoice SDKs, including picoLLM. Anyone who is using Picovoice needs to have a valid AccessKey. You must keep your AccessKey secret. You would need internet connectivity to validate your AccessKey with Picovoice license servers even though the LLM inference is running 100% offline and completely free for open-weight models. Everyone who signs up for Picovoice Console receives a unique AccessKey.

Usage

Create an instance of the engine and generate a prompt completion:

const { PicoLLM } = require("@picovoice/picollm-node");

const pllm = new PicoLLM(
    '${ACCESS_KEY}',
    '${MODEL_PATH}');

const res = await pllm.generate('${PROMPT}');
console.log(res.completion);

Replace ${ACCESS_KEY} with yours obtained from Picovoice Console, ${MODEL_PATH} with the path to a model file downloaded from Picovoice Console, and ${PROMPT} with a prompt string.

To interrupt completion generation before it has finished:

pllm.interrupt()

Instruction-tuned models (e.g., llama-3-8b-instruct, llama-2-7b-chat, and gemma-2b-it) have a specific chat template. You can either directly format the prompt or use a dialog helper:

const dialog = pllm.getDialog();
dialog.addHumanRequest(prompt);

const res = pllm.generate(dialog.prompt());
dialog.addLLMResponse(res.completion);
console.log(res.completion);

Finally, when done, be sure to release the resources explicitly:

pllm.release()

Demos

picoLLM Node.js demo package provides command-line utilities for processing audio using picoLLM.
