picoLLM Chat Web Demo

This is a basic demo to show how to use picoLLM on web browsers, using the IIFE version of the library (i.e. an HTML script tag). It instantiates a picoLLM inference engine on a web worker and enables a back-and-forth conversation with the LLM, similar to ChatGPT.

AccessKey

PicoLLM requires a valid Picovoice AccessKey at initialization. AccessKey acts as your credentials when using Picovoice SDKs. You can get your AccessKey for free. Make sure to keep your AccessKey secret. Signup or Login to Picovoice Console to get your AccessKey.

Models

picoLLM Inference Web Engine supports the following open-weight models. The models are on Picovoice Console.

  • Gemma
    • gemma-2b
    • gemma-2b-it
  • Llama-2
    • llama-2-7b
    • llama-2-7b-chat
    • llama-3-8b
    • llama-3-8b-instruct
  • Mistral
    • mistral-7b-v0.1
    • mistral-7b-instruct-v0.1
    • mistral-7b-instruct-v0.2
  • Phi-2
    • phi2

NOTE: Only gemma and Phi-2 models have been tested on multiple browsers across different platforms. The rest of the models depend on the user's system in order to run properly.
