Introduction

The llama-cpp-agent framework is a tool designed to simplify interactions with Large Language Models (LLMs). It provides an interface for chatting with LLMs, executing function calls, generating structured output, performing retrieval augmented generation, and processing text using agentic chains with tools.

The framework uses guided sampling to constrain the model output to the user defined structures. This way also models not fine-tuned to do function calling and JSON output will be able to do it.

The framework is compatible with the llama.cpp server, llama-cpp-python and its server, and with TGI and vllm servers.

Key Features

  • Simple Chat Interface: Engage in seamless conversations with LLMs.
  • Structured Output: Generate structured output (objects) from LLMs.
  • Single and Parallel Function Calling: Execute functions using LLMs.
  • RAG - Retrieval Augmented Generation: Perform retrieval augmented generation with colbert reranking.
  • Agent Chains: Process text using agent chains with tools, supporting Conversational, Sequential, and Mapping Chains.
  • Guided Sampling: Allows most 7B LLMs to do function calling and structured output. Thanks to grammars and JSON schema generation for guided sampling.
  • Multiple Providers: Works with llama-cpp-python, llama.cpp server, TGI server and vllm server as provider!
  • Compatibility: Works with python functions, pydantic tools, llama-index tools, and OpenAI tool schemas.
  • Flexibility: Suitable for various applications, from casual chatting to specific function executions.

Usage Examples

The llama-cpp-agent framework provides a wide range of examples demonstrating its capabilities. Here are some key examples:

Simple Chat Example using llama.cpp server backend

This example demonstrates how to initiate a chat with an LLM model using the llama.cpp server backend.

View Example

Parallel Function Calling Agent Example

This example showcases parallel function calling using the FunctionCallingAgent class. It demonstrates how to define and execute multiple functions concurrently.

View Example

Structured Output

This example illustrates how to generate structured output objects using the StructuredOutputAgent class. It shows how to create a dataset entry of a book from unstructured data.

View Example

RAG - Retrieval Augmented Generation

This example demonstrates Retrieval Augmented Generation (RAG) with colbert reranking. It requires installing the optional rag dependencies (ragatouille).

View Example

llama-index Tools Example

This example shows how to use llama-index tools and query engines with the FunctionCallingAgent class.

View Example

Sequential Chain Example

This example demonstrates how to create a complete product launch campaign using a sequential chain.

View Example

Mapping Chain Example

This example illustrates how to create a mapping chain to summarize multiple articles into a single summary.

View Example

Knowledge Graph Creation Example

This example, based on an example from the Instructor library for OpenAI, shows how to create a knowledge graph using the llama-cpp-agent framework.

Additional Information

Predefined Messages Formatter

The llama-cpp-agent framework provides predefined message formatters to format messages for the LLM model. The MessagesFormatterType enum defines the available formatters:

  • MessagesFormatterType.MISTRAL: Formats messages using the MISTRAL format.
  • MessagesFormatterType.CHATML: Formats messages using the CHATML format.
  • MessagesFormatterType.VICUNA: Formats messages using the VICUNA format.
  • MessagesFormatterType.LLAMA_2: Formats messages using the LLAMA 2 format.
  • MessagesFormatterType.SYNTHIA: Formats messages using the SYNTHIA format.
  • MessagesFormatterType.NEURAL_CHAT: Formats messages using the NEURAL CHAT format.
  • MessagesFormatterType.SOLAR: Formats messages using the SOLAR format.
  • MessagesFormatterType.OPEN_CHAT: Formats messages using the OPEN CHAT format.
  • MessagesFormatterType.ALPACA: Formats messages using the ALPACA format.
  • MessagesFormatterType.CODE_DS: Formats messages using the CODE DS format.
  • MessagesFormatterType.B22: Formats messages using the B22 format.
  • MessagesFormatterType.LLAMA_3: Formats messages using the LLAMA 3 format.
  • MessagesFormatterType.PHI_3: Formats messages using the PHI 3 format.

Creating Custom Messages Formatter

You can create your own custom messages formatter by instantiating the MessagesFormatter class with the desired parameters:

from llama_cpp_agent.messages_formatter import MessagesFormatter, PromptMarkers, Roles

custom_prompt_markers = {
    Roles.system: PromptMarkers("<|system|>", "<|endsystem|>"),
    Roles.user: PromptMarkers("<|user|>", "<|enduser|>"),
    Roles.assistant: PromptMarkers("<|assistant|>", "<|endassistant|>"),
    Roles.tool: PromptMarkers("<|tool|>", "<|endtool|>"),
}

custom_formatter = MessagesFormatter(
    pre_prompt="",
    prompt_markers=custom_prompt_markers,
    include_sys_prompt_in_first_user_message=False,
    default_stop_sequences=["<|endsystem|>", "<|enduser|>", "<|endassistant|>", "<|endtool|>"]
)
