godot-llama-cpp

Run large language models in Godot. Powered by llama.cpp.

Overview

This library aims to provide a high-level interface to run large language models in Godot, following Godot's node-based design principles.

@onready var llama_context = %LlamaContext

var messages = [
  { "sender": "system", "text": "You are a pirate chatbot who always responds in pirate speak!" },
  { "sender": "user", "text": "Who are you?" }
]
var prompt = ChatFormatter.apply("llama3", messages)
var completion_id = llama_context.request_completion(prompt)

while (true):
  var response = await llama_context.completion_generated
  print(response["text"])

  if response["done"]: break

Features

• Platform and compute backend support:

  Platform	CPU	Metal	Vulkan	CUDA
  macOS
  Linux
  Windows

• Asynchronous completion generation
• Support any language model that llama.cpp supports in GGUF format
• GGUF files are Godot resources

Roadmap

• Chat completions support via dedicated library for jinja2 templating in zig
• Grammar support
• Multimodal models support
• Embeddings
• Vector database using LibSQL
