Relay

Relay is an API-based AI service that uses OpenGPU Network as its infrastructure.

What Is Relay?

Relay provides a developer-friendly API gateway to GPU compute—no blockchain knowledge required.

• Familiar APIs: Compatible with standard model interfaces

• No wallet needed: Standard API key authentication

• Multiple AI capabilities: Chat, TTS, ASR, image generation

• Dual-mode: Can use OpenGPU Network (decentralized) or direct relaying (central routing)

When to Use Relay vs OpenGPU

Use Relay	Use OpenGPU
Want simple API access	Want full protocol control
Don't need blockchain transparency	Need on-chain verification
Prefer API keys over wallets	Building custom Sources
Real-time, low-latency needed	Building on the protocol

Quick Example

curl -X POST https://relay.opengpu.network/api/ollama/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: YOUR_API_KEY" \
  -d '{
    "model": "llama3.2:3b",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'
