0G Network Developer Guide

Last updated: 2026-03-30 Source: https://docs.0g.ai

Overview

0G (Zero Gravity) is a decentralized storage + data availability + AI compute network designed for AI applications.

Network Information

Three-Layer Architecture

1. Storage Layer (0G Storage)

Distributed storage, suitable for AI training data and model files:

# Install 0G CLI
pip install 0g-sdk

# Upload file
0g storage upload --file model.bin --network testnet

# Download file
0g storage download --hash 0x... --output model.bin

2. Data Availability Layer (0G DA)

import { ZgClient } from '@0g-sdk/client'

const client = new ZgClient({ rpc: 'https://evmrpc-testnet.0g.ai' })

// Submit data to DA
const txHash = await client.da.submit({
  data: Buffer.from('my data'),
  namespace: 'my-app',
})

3. AI Compute Layer (0G Compute)

import og_compute

# Submit AI inference task
task = og_compute.submit(
    model="llama-3-8b",
    input={"prompt": "Hello, World!"},
    network="testnet"
)
result = og_compute.wait(task.id)
