0G Compute Network

This skill provides instructions for building with the 0G Compute Network — a decentralized GPU marketplace for AI inference and model fine-tuning. Follow these patterns exactly when generating code.

Code Generation Rules

1. Copy code patterns from this skill verbatim. Do NOT generate from training data.
2. Call processResponse() after every API response (see processResponse section below).
3. Use environment variables for private keys. Never hardcode secrets.
4. Route users to testnet for initial development.

When unsure about a pattern, reference the detailed guides:

• Inference patterns: references/inference.md
• Fine-tuning workflow: references/fine-tuning.md
• Account management: references/account-management.md
• Production examples: references/examples/

Network Information

Network	RPC URL	Inference	Fine-tuning
Mainnet	https://evmrpc.0g.ai	Yes	Yes
Testnet	https://evmrpc-testnet.0g.ai	Yes	Yes

Model availability changes frequently. Always use broker.inference.listService() or 0g-compute-cli inference list-providers to check current models. On-chain model names use org/model-name format.

Prerequisites

node --version  # Must be >= 22.0.0
pnpm add @0glabs/0g-serving-broker        # SDK for applications
pnpm add @0glabs/0g-serving-broker -g     # CLI for direct usage

Quick Setup

0g-compute-cli setup-network              # Choose testnet or mainnet
0g-compute-cli login                       # Login with wallet private key
0g-compute-cli deposit --amount 10         # Deposit funds
0g-compute-cli get-account                 # Check balance

Inference (SDK)

import { ethers } from "ethers";
import { createZGComputeNetworkBroker } from "@0glabs/0g-serving-broker";

const RPC_URL = process.env.NODE_ENV === 'production'
  ? "https://evmrpc.0g.ai"
  : "https://evmrpc-testnet.0g.ai";

const provider = new ethers.JsonRpcProvider(RPC_URL);
const wallet = new ethers.Wallet(process.env.PRIVATE_KEY!, provider);
const broker = await createZGComputeNetworkBroker(wallet);

// Discover services
const services = await broker.inference.listService();
services.forEach(s => {
  console.log(`${s.provider} | ${s.model} | ${s.serviceType}`);
});

// Make inference request
const { endpoint, model } = await broker.inference.getServiceMetadata(providerAddress);
const headers = await broker.inference.getRequestHeaders(providerAddress);

const response = await fetch(`${endpoint}/chat/completions`, {
  method: "POST",
  headers: { "Content-Type": "application/json", ...headers },
  body: JSON.stringify({ messages, model })
});

const data = await response.json();

// Extract chatID (see chatID table below)
let chatID = response.headers.get("ZG-Res-Key") || response.headers.get("zg-res-key");
if (!chatID) chatID = data.id;

// CRITICAL: Always call processResponse
await broker.inference.processResponse(
  providerAddress,              // 1st: provider address
  chatID,                       // 2nd: response identifier for verification
  JSON.stringify(data.usage)    // 3rd: usage data for fee calculation
);

For streaming, browser SDK, cURL, and Python examples, see references/inference.md.

processResponse (CRITICAL)

Call broker.inference.processResponse() after EVERY API response for fee settlement and TEE verification.

await broker.inference.processResponse(
  providerAddress,              // 1st: provider address
  chatID,                       // 2nd: response identifier for verification
  JSON.stringify(data.usage)    // 3rd: usage data for fee calculation
);

Parameter order: provider, chatID, usageData. Do NOT reorder.

chatID Retrieval by Service Type

Always try ZG-Res-Key response header first. Use fallback only when header is absent.

Service Type	chatID Source	Fallback
Chatbot	ZG-Res-Key header	data.id from response body
Text-to-Image	ZG-Res-Key header	none
Speech-to-Text	ZG-Res-Key header	none
Chatbot Streaming	ZG-Res-Key header	id from stream chunk
Audio Streaming	ZG-Res-Key header	none

Fine-tuning

Fine-tuning is available on both mainnet and testnet. It is a 6-step CLI process: list providers, upload dataset, calculate tokens, create task, monitor, download and decrypt.

For the complete workflow, see references/fine-tuning.md.

Account Management

The 0G Compute Network uses Main Accounts (deposits/withdrawals) and Provider Sub-Accounts (service payments). Sub-account refunds have a 24-hour lock period.

0g-compute-cli get-account                                    # Check balance
0g-compute-cli deposit --amount 10                             # Deposit to main
0g-compute-cli transfer-fund --provider <ADDR> --amount 5      # Transfer to sub-account
0g-compute-cli retrieve-fund                                   # Retrieve from sub (24h lock)
0g-compute-cli refund --amount 5                               # Withdraw to wallet

For detailed account management, see references/account-management.md.

CLI Quick Reference

# Inference
0g-compute-cli inference list-providers                        # List all providers
0g-compute-cli inference verify --provider <ADDR>              # Verify TEE attestation
0g-compute-cli inference acknowledge-provider --provider <ADDR> # Required before first use
0g-compute-cli inference get-secret --provider <ADDR>          # Get API key for direct calls
0g-compute-cli inference serve --provider <ADDR> --port 3000   # Local OpenAI-compatible proxy

# Fine-tuning
0g-compute-cli fine-tuning list-providers                      # List fine-tuning providers
0g-compute-cli fine-tuning list-models                         # List available models

# Web UI
0g-compute-cli ui start-web                                    # Launch at localhost:3090

Troubleshooting

Problem	Solution
Insufficient balance	deposit --amount 5 then transfer-fund --provider <ADDR> --amount 2
Provider not acknowledged	inference acknowledge-provider --provider <ADDR>
Provider busy (fine-tuning)	Wait and retry, or choose a different provider
Web UI port conflict	ui start-web --port 3091
