OpenGradient SDK

The OpenGradient SDK enables developers to build applications using OpenGradient's decentralized, end-to-end verified AI infrastructure. The SDK provides a simple interface to run ML and LLM inference, manage models, and deploy automated workflows - all secured by the OpenGradient network.

For LLM inference, the SDK provides a convenient Python wrapper around the x402 Gateway, handling HTTP requests and payment flows automatically. You can also use x402 directly from any language if you prefer more control over the integration. Beyond LLM convenience, the SDK provides additional capabilities like ML inference, automated workflows, and model management that are not available through x402 alone.

The SDK is currently available for Python, a TypeScript version is under development. You can directly check the Python API Reference.

In addition to the OpenGradient Python library, the SDK also includes a CLI tool called opengradient for easier access and iteration.

SDK Features

• ML Inference & Workflows: Run ML model inference and deploy automated workflows that execute on a schedule with live oracle data (alpha testnet only)
• LLM Inference: Use secure and verifiable large language models for completions and chat, with support for tool usage and TEE execution
• Model Management: Upload, manage, and organize your models on the Model Hub

Installation

To install the OpenGradient Python SDK and CLI, run the following command:

pip install opengradient

You can also find the SDK on PyPI.

NOTE

Windows Users: temporarily enable WSL when installing opengradient, fix in progress.

Credentials Setup

LLM Inference (Testnet)

To run LLM inference, you need an Ethereum-compatible wallet (e.g., MetaMask) funded with $OPG testnet tokens on Base Sepolia.

Property	Value
Payment Network	Base Sepolia
Token	$OPG (0x240b09731D96979f50B2C649C9CE10FcF9C7987F)
Chain ID	84532

import opengradient as og

client = og.Client(private_key="0x...")

NOTE

Make sure your wallet has $OPG testnet tokens on Base Sepolia. You can get tokens from our faucet.

ML Inference & Model Management (Alpha Testnet)

To use ML inference, workflows, or model management features on the alpha testnet, you need to create 2 accounts:

• Model Hub account: You can create this using your email and password on the Hub Sign Up.
• OpenGradient alpha account: A blockchain account on the OpenGradient alpha testnet. You can use any existing Ethereum-compatible wallet (e.g., MetaMask) or create a new one using our SDK (see below).

import opengradient as og

client = og.Client(private_key="<private_key>", email="<email>", password="<password>")

We provide an account creation wizard in our SDK that guides you through this process. You can access it by running:

opengradient config init

NOTE

The wizard will also take you to our Test Faucet, where you can fund your account with testnet tokens.

CLI Setup

Check that the OpenGradient client reflects your settings (private key, email, etc.)

opengradient config show

NOTE

You can run opengradient config init if your configuration is not currently set up.

To ensure everything is correctly set up, run the following inference:

opengradient infer -m QmbUqS93oc4JTLMHwpVxsE39mhNxy6hpf6Py3r9oANr8aZ --input '{"num_input1":[1.0, 2.0, 3.0], "num_input2":10, "str_input1":["hello", "ONNX"], "str_input2":" world"}'

More Information

To see all commands and parameters we support in the CLI, you can run:

opengradient --help
