ovos-solver-gguf-plugin 0.0.0a1

A question solver plugin for OVOS

GGUF Solver

Overview

GGUFSolver is a question-answering module that utilizes GGUF models to provide responses to user queries. This solver streams utterances for real-time interaction and is built on the ovos_plugin_manager.templates.solvers.QuestionSolver framework.

Features

• Supports loading GGUF models from local files or remote repositories.
• Streams partial responses for improved interactivity.
• Configurable persona and verbosity settings.
• Capable of providing spoken answers.

Configuration

GGUFSolver requires a configuration dictionary. The configuration should at least specify the model to use. Here is an example configuration:

cfg = {
    "model": "TheBloke/notus-7B-v1-GGUF",
    "remote_filename": "*Q4_K_M.gguf"
}

• model: The identifier for the model. It can be a local file path or a repository ID for a remote model.
• n_gpu_layers: how many layer to offload to GPU, -1 to offload all. default 0
• remote_filename: The specific filename to load from a remote repository.
• chat_format: (Optional) Chat formatting settings.
• verbose: (Optional) Set to True for detailed logging.
• persona: (Optional) Persona for the system messages. Default is "You are a helpful assistant who gives short factual answers".
• max_tokens: (Optional) Maximum tokens for the response. Default is 512.

NOTE: for GPU support llama.cpp needs to be compiled with

CMAKE_ARGS="-DGGML_CUDA=on" FORCE_CMAKE=1 pip install llama-cpp-python --force-reinstall --no-cache-dir

Usage

Initializing the Solver

from ovos_gguf_solver import GGUFSolver
from ovos_utils.log import LOG

LOG.set_level("DEBUG")

cfg = {
    "model": "TheBloke/notus-7B-v1-GGUF",
    "remote_filename": "*Q4_K_M.gguf"
}

solver = GGUFSolver(cfg)

Streaming Utterances

Use the stream_utterances method to stream responses. This is particularly useful for real-time applications such as voice assistants.

query = "tell me a joke about aliens"
for sentence in solver.stream_utterances(query):
    print(sentence)

Getting a Full Answer

Use the get_spoken_answer method to get a complete response.

query = "What is the capital of France?"
answer = solver.get_spoken_answer(query)
print(answer)

Integrating with Persona Framework

To integrate GGUFSolver with the OVOS Persona Framework and pass solver configurations, follow these examples.

Each example demonstrates how to define a persona configuration file with specific settings for different models or configurations.

To use any of these configurations, run the OVOS Persona Server with the desired configuration file:

$ ovos-persona-server --persona gguf_persona_remote.json

Replace gguf_persona_remote.json with the filename of the configuration you wish to use.

Example 1: Using a Remote GGUF Model

This example shows how to configure the GGUFSolver to use a remote GGUF model with a specific persona.

gguf_persona_remote.json:

{
  "name": "Notus",
  "solvers": [
    "ovos-solver-gguf-plugin"
  ],
  "ovos-solver-gguf-plugin": {
    "model": "TheBloke/notus-7B-v1-GGUF",
    "remote_filename": "*Q4_K_M.gguf",
    "persona": "You are an advanced assistant providing detailed and accurate information.",
    "verbose": true
  }
}

In this configuration:

• ovos-solver-gguf-plugin is set to use a remote GGUF model TheBloke/notus-7B-v1-GGUF with the specified filename.
• The persona is configured to provide detailed and accurate information.
• verbose is set to true for detailed logging.

Example 2: Using a Local GGUF Model

This example shows how to configure the GGUFSolver to use a local GGUF model.

gguf_persona_local.json:

{
  "name": "LocalGGUFPersona",
  "solvers": [
    "ovos-solver-gguf-plugin"
  ],
  "ovos-solver-gguf-plugin": {
    "model": "/path/to/local/model/gguf_model.gguf",
    "persona": "You are a helpful assistant providing concise answers.",
    "max_tokens": 256
  }
}

In this configuration:

• ovos-solver-gguf-plugin is set to use a local GGUF model located at /path/to/local/model/gguf_model.gguf.
• The persona is configured to provide concise answers.
• max_tokens is set to 256 to limit the response length.
