🚀 ModelGrid

vLLM deployment manager with an OpenAI-compatible API, clustering foundations, and a public OSS model catalog.

ModelGrid is a root-level daemon that turns any GPU-equipped machine into a vLLM-serving node. It manages single-model vLLM deployments across NVIDIA, AMD, and Intel GPUs, exposes a unified OpenAI-compatible API, and resolves deployable models from list.modelgrid.com.

Configuration Options

Option	Description	Default
api.port	API server port	8080
api.host	Bind address	0.0.0.0
api.apiKeys	Valid API keys	[]
api.rateLimit	Requests per minute	60
docker.runtime	Container runtime	docker
gpus.autoDetect	Auto-detect GPUs	true
models.autoDeploy	Auto-start deployments on demand	true
models.autoLoad	Models to preload on start	[]
cluster.role	Cluster mode	standalone
cluster.sharedSecret	Shared secret for /_cluster/*	unset
cluster.advertiseUrl	URL advertised to other nodes	http://127.0.0.1:8080
cluster.controlPlaneUrl	Control-plane URL for workers	unset
checkInterval	Health check interval (ms)	30000

🕸️ Clustering

Cluster mode uses ModelGrid's internal control-plane endpoints to:

• register worker nodes
• advertise locally deployed models
• persist desired deployment targets separately from live heartbeats
• schedule new deployments onto healthy nodes with enough VRAM
• proxy OpenAI-compatible requests to the selected node gateway
• exclude cordoned or draining nodes from new placements

Minimal setup:

{
  "cluster": {
    "enabled": true,
    "nodeName": "worker-a",
    "role": "worker",
    "sharedSecret": "replace-me-with-a-random-secret",
    "advertiseUrl": "http://worker-a.internal:8080",
    "controlPlaneUrl": "http://control.internal:8080",
    "heartbeatIntervalMs": 5000
  }
}

For the control plane, set role to control-plane and advertiseUrl to its reachable API URL. Set the same cluster.sharedSecret on every node to protect internal cluster endpoints.

Runtime state files:

• /var/lib/modelgrid/cluster-state.json for live node heartbeats
• /var/lib/modelgrid/cluster-control-state.json for desired deployments and node lifecycle state

📚 Model Catalog

ModelGrid resolves deployable models from list.modelgrid.com. The catalog is public, versioned, and describes:

• canonical model IDs
• aliases
• minimum VRAM and GPU count
• vLLM launch defaults
• desired replica counts
• capabilities like chat, completions, and embeddings

Default catalog includes:

• Qwen/Qwen2.5-7B-Instruct
• meta-llama/Llama-3.1-8B-Instruct
• deepseek-ai/DeepSeek-R1-Distill-Qwen-7B
• BAAI/bge-m3

Custom registry source:

// models.json
{
  "version": "1.0",
  "generatedAt": "2026-04-20T00:00:00.000Z",
  "models": [
    {
      "id": "meta-llama/Llama-3.1-8B-Instruct",
      "engine": "vllm",
      "source": { "repo": "meta-llama/Llama-3.1-8B-Instruct" },
      "capabilities": { "chat": true },
      "requirements": { "minVramGb": 18 },
      "launchDefaults": { "replicas": 2 }
    }
  ]
}

Configure with:

{
  "models": {
    "registryUrl": "https://your-server.com/models.json"
  }
}
