# Overview

The OpenGPU Ecosystem comprises the network infrastructure and the applications that connect to it.

## OpenGPU Network

The core infrastructure:

| Layer                  | Description                                                                         |
| ---------------------- | ----------------------------------------------------------------------------------- |
| **OpenGPU Blockchain** | L1 EVM-compatible chain handling settlement, security, and transparency             |
| **OpenGPU Protocol**   | Smart contracts (Nexus, Terminal, Vault, Controller) governing the task marketplace |

## OpenGPU Applications

Tools that connect to the network:

| Application                                                      | Type    | Purpose                               |
| ---------------------------------------------------------------- | ------- | ------------------------------------- |
| [Client App](/opengpu-network/ecosystem/client-app.md)           | Webapp  | Publish sources and tasks             |
| [Provider Suite](/opengpu-network/ecosystem/provider-suite.md)   | Desktop | Turn your GPU into a network provider |
| [Management dApp](/opengpu-network/ecosystem/management-dapp.md) | Webapp  | Monitor activity, manage accounts     |
| [SDK](/opengpu-network/ecosystem/sdk.md)                         | Library | Programmatic access for developers    |

## External Products

Products built on OpenGPU:

| Product   | Description                                                                                                                                |

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://opengpu-network.gitbook.io/opengpu-network/ecosystem/overview.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
