What is mycellm?

mycellm pools GPUs across the internet into a single inference network. Anyone can contribute compute and earn credits. Anyone can chat with frontier models for free.

• OpenAI-compatible API — drop-in replacement at /v1/chat/completions
• P2P architecture — no central GPU cluster, no vendor lock-in
• Ed25519 cryptographic identity — signed receipts, verifiable accounting
• Multi-network federation — public swarm, private orgs, fleet management
• iOS app — your iPad is a first-class inference node (Metal + llama.cpp)

Quick Start

# Install
pip install mycellm

# Create identity and join the public network
mycellm init

# Start serving (auto-detects GPU)
mycellm serve

Your node is now live. Load a model and start earning credits:

# Interactive chat
mycellm chat

# Or use the OpenAI-compatible API
curl http://localhost:8420/v1/chat/completions \
  -H "Content-Type: application/json" \
  -d '{"model": "auto", "messages": [{"role": "user", "content": "Hello!"}]}'

One-liner Install

curl -fsSL https://mycellm.ai/install.sh | sh

Or with Docker:

docker run -p 8420:8420 -p 8421:8421/udp ghcr.io/mycellm/mycellm serve

How It Works

You (consumer) ──QUIC──▶ Bootstrap (relay) ──QUIC──▶ Seeder (GPU)
                                                       │
                                                  llama.cpp / vLLM
                                                       │
                                              Tokens stream back ◀──

1. Consumers send prompts via the API or chat interface
2. Bootstrap relays requests to available seeders via QUIC
3. Seeders run inference on their local GPU and stream tokens back
4. Credits flow to seeders — signed Ed25519 receipts for every request
5. NAT traversal enables direct P2P connections when possible

Architecture

Layer	Purpose	Tech
Canopy	Client access	iOS app, CLI chat, web UI, OpenAI API
Mycelium	Routing & discovery	QUIC transport, Kademlia DHT, STUN/ICE
Roots	Inference compute	llama.cpp (Metal/CUDA/ROCm/CPU), vLLM
Ledger	Accounting	Ed25519 signed receipts, per-network credit tracking

Features

Inference

• llama.cpp backend with Metal, CUDA, ROCm, and CPU support
• Streaming token generation via SSE
• Model management — download from HuggingFace, load/unload, scope control
• Thermal throttling — auto-adjusts on mobile devices

Networking

• QUIC transport with bidirectional streams (NWConnectionGroup on iOS, aioquic on Python)
• NAT traversal — STUN discovery + UDP hole punching for direct P2P
• HTTP fallback — works when QUIC is blocked
• Bootstrap relay — always works, even behind symmetric NAT

Security

• Ed25519 identity — account key → device cert → peer ID
• Signed receipts — cryptographic proof of inference served
• Sensitive Data Guard — regex scanning for API keys, passwords, PII
  • Client-side: blocks/redirects before sending
  • Gateway: returns 422 with explanation
  • Bypass: X-Privacy-Override: acknowledged header
• Fleet management — remote node control with admin key auth

Multi-Network

• Public network — open to all, auto-approved
• Private networks — invite-only with Ed25519-signed tokens
• Federation — gateway nodes bridge multiple networks
• Fleet — enterprise management with remote commands
• Trust levels — strict (verify all), relaxed (verify, don't enforce), honor (trusted LAN)

iOS App

The mycellm iOS app makes any iPhone or iPad a first-class network node.

• On-device inference — llama.cpp on Metal, streaming tokens
• Network chat — route to any model on the public network
• QUIC P2P — authenticated with the bootstrap, serves inference
• Sensitive Data Guard — auto-routes sensitive prompts to local model
• OLED screensaver — brand-colored mushroom with spore particles

Requires iOS 17.0+. Coming soon to TestFlight.

Configuration

# Environment variables
MYCELLM_API_HOST=0.0.0.0        # API listen address
MYCELLM_API_PORT=8420            # API port
MYCELLM_QUIC_PORT=8421           # QUIC transport port
MYCELLM_LOG_LEVEL=INFO           # Logging level
MYCELLM_FLEET_ADMIN_KEY=...      # Fleet management key (optional)
MYCELLM_NO_DHT=true              # Disable Kademlia DHT

See docs/config for full reference.

API

OpenAI-compatible. Works with any client that supports the OpenAI API format.

from openai import OpenAI

client = OpenAI(base_url="http://localhost:8420/v1", api_key="unused")
response = client.chat.completions.create(
    model="auto",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(response.choices[0].message.content)

Endpoints

Method	Path	Description
GET	/health	Health check
GET	/v1/models	List available models
POST	/v1/chat/completions	Chat (streaming + non-streaming)
GET	/v1/node/status	Node status
GET	/v1/node/peers	Connected peers
POST	/v1/node/models/load	Load a model
POST	/v1/node/federation/invite	Create network invite
POST	/v1/node/federation/join	Join a network

See API docs for the full reference.

Private Networks

Create a private network for your team, lab, or organization:

# On the bootstrap node
mycellm init --bootstrap --name "my-org"

# Generate an invite
mycellm network invite --max-uses 10

# On member nodes
mycellm network join mcl_invite_eyJ...
