🧱 Lamina LLM Serve

Lamina LLM Serve is a local-first, centralized model-serving layer for Lamina OS. It manages downloads and runs models so agents share consistent, persistent access—ensuring efficiency and symbolic alignment across the sanctuary.

🌱 Purpose

lamina-llm-serve solves common issues in multi-agent AI environments:

• Prevents redundant downloads of large models
• Offers a unified directory and manifest for all system models
• Supports multiple backends (e.g., llama.cpp, mlc, vllm)
• Keeps model configuration cleanly decoupled from agent implementation

It serves as the source of truth for all LLM usage across lamina-core.

🎞️ Model Manifest (models.yaml)

Each model is described with its local path and associated runtime backend:

models:
  llama3-70b-q4_k_m:
    path: /models/llama3-70b-q4_k_m/model.gguf
    backend: llama.cpp
  yi-34b-awq:
    path: /models/yi-34b-awq/
    backend: mlc
  llama3-70b-q5_k_m:
    path: /models/llama3-70b-q5_k_m/
    backend: llama.cpp
  mistral-7b-instruct:
    path: /models/mistral-7b-instruct/
    backend: llama.cpp

💠 Usage Within Lamina OS

In lamina-core, agents reference models through this service:

• Model-to-agent mapping occurs within Lamina OS
• lamina-llm-serve is model aware, acting as a unified server rather than a simple cache
• Ensures consistent, centralized loading and version control

Example usage:

from lamina_llm_serve import ModelManager

manager = ModelManager()
models = manager.list_models()
print(f"Available models: {models}")

🔧 Backends Supported

🧪 REST API

The included HTTP server provides:

• GET /models – List all available models
• GET /models/<name> – Get specific model info
• GET /backends – List available backends
• POST /download – Download a model
• GET /health – Server health check

Start the server:

python -m lamina_llm_serve.server --port 8000

🥐 Setup Instructions

1. Install the package:

   pip install lamina-llm-serve
   

2. Download models using the CLI:

   # List available models for download
   python scripts/model-manager.py list-downloadable
   
   # Download a specific model
   python scripts/model-manager.py download llama3.2-1b-q4_k_m --source huggingface
   

3. Validate your setup:

   python scripts/model-manager.py validate
   

🛡️ Philosophy

Models are not interchangeable engines—they are vessels for vow-bound symbolic presence. This serving layer anchors those vessels with intention, clarity, and breath.
