Momahub: Hub-and-spoke distributed AI inference network.

Momahub - Hub-and-spoke distributed AI inference network

Users submit requests to a Hub, the Hub dispatches them to Agent nodes running Ollama.

Requirements

• Python >= 3.11
• Ollama on every agent node
• GPU recommended (CPU-only works but will be slow)

Quick start

# Install Ollama on all GPU nodes
curl -fsSL https://ollama.com/install.sh | sh
bash scripts/pull_ollama.sh

# Create virtualenv
conda create -n moma python=3.11
conda activate moma

# Git clone
git clone https://github.com/digital-duck/momahub.py.git

# Install from source
pip install -e .

# (Re)Start the hub on a GPU node
moma hub up

# Get hub node IP address, to be used by an agent node to join the hub
hostname -I 
# hub-ip-address

# (Re)Start an agent on all GPU nodes including hub node
moma join http://<hub-ip-address>:8000

# Submit a task from any GPU node
moma submit "Explain distributed inference in two sentences" --model <model of your choice pulled before>

# Monitor Momahub status

Features

Momahub provides a robust suite of tools for distributed AI inference. For a detailed list of current capabilities and our upcoming development roadmap (including Go re-implementation and cryptographic security), please see FEATURES.md.

• Hub-and-spoke dispatch — automatic agent selection by compute tier, VRAM, and model availability
• Multi-hub clustering — peer hubs share capabilities and forward tasks across the network
• Compute tiers — agents ranked PLATINUM / GOLD / SILVER / BRONZE by measured tokens-per-second
• Reward ledger — tracks operator contributions (tasks completed, tokens generated, credits earned)
• SPL integration — run structured prompt programs on the grid with ON GRID / WITH VRAM syntax
• Streamlit dashboard — real-time overview, grid monitor, rewards, SPL runner, Text2SPL, and Paper Digest
• CLI (moma) — full grid management from the terminal

Proven Performance

Momahub has been validated in real-world LAN environments:

• 3-GPU Milestone (2026-03-08): Successfully deployed across 3 GPU nodes using 2 NVIDIA GTX 1080 Ti (11GB VRAM) + 1 NVIDIA GTX 1050 Ti (4GB VRAM). Achieved 100% completion rate on burst stress tests with automated agent-side queueing and hub-level load balancing.
• Tiers: Measured between 50 and 100 TPS on benchmarked models.

Research

Momahub - the python implementation for this upcoming arxiv paper (in preparation)

Momahub: A Prompt Compiler and Decentralized LLM Inference Network Wen G. Gong (2026)

The paper introduces two key ideas:

1. The Prompt Compiler — reframing Text2SPL as a full compiler pipeline (front-end NL→SPL, mid-end CTE DAG optimisation, back-end model/VRAM mapping), with SPL as the intermediate representation between human intent and GPU execution. The compiler is self-hosting: it runs on the Momahub it compiles for.

2. The Distributed Inference Runtime — Momahub as the runtime layer that abstracts distributed consumer GPUs into a programmable compute surface, analogous to the JVM or the Linux kernel for traditional computing.
