What is Local LLM NPC?
Local LLM NPC is an open-source framework that brings AI-powered Non-Player Characters (NPCs) to your applications using self-hosted Local Large Language Models (LLMs). Unlike cloud-dependent AI services, this project enables developers to run fully customizable and autonomous NPCs directly on their own machines — ensuring privacy, reducing latency, and eliminating recurring cloud costs.
By combining the power of local LLMs with a modular design, Local LLM NPC delivers intelligent, context-aware, and immersive NPC behavior for use in games, chatbots, virtual assistants, and experimental AI projects.
Key Features of Local LLM NPC
- Self-Hosted AI: Run advanced language models on your own hardware — no cloud API required.
- Modular NPC Architecture: Create and manage NPC personalities, memories, and decision-making with flexible components.
- Customizable Behavior: Tailor NPC responses and logic to fit any interactive use case.
- Open Source & Extensible: Built by the community — extend it with your own features or LLM backends.
- Privacy-Focused: Keep all data and AI processing local to ensure complete control over your information.
- Cross-Platform Compatibility: Easily deploy across Windows, macOS, and Linux systems.
- Pre-Built Examples: Get started quickly with ready-to-use NPC templates and sample configurations.
How to Install Local LLM NPC
Setting up Local LLM NPC is simple. Ensure you have Python 3
and the required dependencies installed, then follow the steps below:
git clone https://github.com/code-forge-temple/local-llm-npc.git
cd local-llm-npc
python3 -m venv venv
source venv/bin/activate # On Windows use: venvScriptsactivate
pip install -r requirements.txt
After setup, make sure a local LLM backend is configured — the NPC framework depends on it to function properly.
How to Use Local LLM NPC
Once installed, you can interact with your NPCs through the command line or integrate them directly into your applications. The repository includes helpful scripts and configurations to get you started right away.
Common steps include:
- Launching an NPC instance using a predefined personality script.
- Sending user input and receiving intelligent, context-aware responses.
- Customizing NPC goals, memories, and response logic for your own projects.
Code Example
Here’s a simple example that demonstrates how to create and chat with an NPC locally:
from local_llm_npc import NPC
# Initialize an NPC with a custom personality
npc = NPC(name="Guardian", personality="calm and wise")
# Ask a question
response = npc.ask("What is the weather like today?")
print(response)
More comprehensive scripts and examples can be found inside the examples/
directory of the repository.

Additional Resources
What Local LLM models are supported?
Local LLM NPC supports multiple open-source local language models compatible with Python. Its modular design makes it easy to integrate additional models — including GPT-like architectures that can run fully offline.
Can I use cloud-hosted models with Local LLM NPC?
While the framework is optimized for local models, developers can integrate cloud APIs if necessary. However, doing so may reduce privacy and increase latency.
How customizable are NPC personalities?
Extremely! You can define detailed NPC personalities, memories, and goals using configuration files or Python scripts — enabling unique, dynamic interactions for every project.
Is there a demo or live preview available?
Currently, there’s no hosted demo. You can, however, run the included examples locally to explore NPC interactions in real time.
How can I contribute to the project?
You can contribute by reporting issues, suggesting new features, improving documentation, or submitting code via pull requests on GitHub.
