LLaMA AIConfig ModelParser Extension

Overview

This package is a lightweight ModelParser extension for AIConfig which provides support for running local GGUF LLaMA models in AIConfig prompts. All GGUF LLaMA models from https://huggingface.co/TheBloke?search_models=gguf should be supported. Under the hood, this package leverages node-llama-cpp for prompt execution.

Install

yarn add aiconfig
yarn add aiconfig-extension-llama

Load Models

By default, LlamaModelParser will look for .gguf models within ./models folder relative to the running process. To use a different directory, specify the model directory when constructing the parser:

const parser = new LlamaModelParser(path.resolve('path', 'to', 'models'));

The directory must contain models meeting the following criteria:

• Must be valid GGUF format models with .gguf extension
• Name must contain the model name registered for use in the parser; e.g. AIConfigRuntime.registerModelParser(llamaModelParser, ["llama-2-7b-chat"]) must have a .gguf file with name containing llama-2-7b-chat

We recommend downloading the models provided by TheBloke on HuggingFace: https://huggingface.co/TheBloke?search_models=gguf. For example, to download a few different models:

curl -L https://huggingface.co/TheBloke/Llama-2-7B-Chat-GGUF/resolve/main/llama-2-7b-chat.Q4_K_M.gguf --output ./models/llama-2-7b-chat.Q4_K_M.gguf
curl -L https://huggingface.co/TheBloke/Llama-2-13B-chat-GGUF/resolve/main/llama-2-13b-chat.Q4_K_M.gguf --output ./models/llama-2-13b-chat.Q4_K_M.gguf
curl -L https://huggingface.co/TheBloke/CodeUp-Llama-2-13B-Chat-HF-GGUF/resolve/main/codeup-llama-2-13b-chat-hf.Q4_K_M.gguf --output ./models/codeup-llama-2-13b-chat-hf.Q4_K_M.gguf

Example Usage

const llamaModelParser = new LlamaModelParser();

AIConfigRuntime.registerModelParser(llamaModelParser, [
  "llama-2-7b-chat",
]);

// A local aiconfig containing a prompt with name 'promptName' and
// model "llama-2-7b-chat"
const config = AIConfigRuntime.load("./llama-aiconfig.json");

const response = await config.run("promptName");

Testing Package Before Publishing

Before publishing the package, ensure it works locally within the ask-llama.ts cookbook.

Note, if a local tarball already exists, remove it before continuing. e.g.:

rm aiconfig-extension-llama-v1.0.0.tgz

Then create the local package:

rm -rf dist && yarn build && yarn pack

In the consuming package (e.g. cookbooks/llama/typescript), update the package.json to point to the local package, e.g.:

"dependencies": {
  ...
  "aiconfig-extension-llama": "file:/Users/ryanholinshead/Projects/aiconfig/extensions/llama/typescript/aiconfig-extension-llama-v1.1.0.tgz"
},

and update the tsconfig.json in the consuming package to find the type declarations:

"compilerOptions": {
  ...
  "paths": {
    "aiconfig-extensions-llama": ["./node_modules/aiconfig-extensions-llama"]
  }
}

Then, in the consuming package, load the local package (ensuring yarn cache is cleared firs):

rm -rf node_modules && rm yarn.lock && yarn cache clean && yarn
