# Welcome to Lium

Lium is a decentralized GPU rental marketplace built on **Bittensor Subnet 51**. Providers contribute GPU resources to a global pool; renters access those resources on demand; validators keep everyone honest by scoring GPU performance and distributing TAO rewards fairly.

## Pick your audience

Choose the section that matches what you're here to do:

| Audience | I want to… | Start here |
|----------|-----------|------------|
| **Providers** | Contribute GPU resources and earn TAO | [Providers →](/providers) |
| **Validators** | Run validation, score providers, maintain integrity | [Validators →](/validators) |
| **Renters** | Rent GPU compute for ML / data workloads on lium.io | [Renters →](/pod-users) |
| **Developers** | Build with the Lium API or CLI | [Developers →](/developers) |

## Agent access

This site is agent-native:

- Every page is reachable as `<page-url>.md` (e.g. [`/providers/quickstart.md`](/providers/quickstart.md)).
- Send `Accept: text/markdown` to any page URL to get raw markdown.
- AI agents can use the `/mcp` endpoint (`search` + `read_page` tools).
- `/llms.txt` and `/llms-full.txt` are at the site root per the [llmstxt.org](https://llmstxt.org) spec.

## What is Bittensor Subnet 51?

The Lium compute subnet on Bittensor is a decentralized network where providers contribute GPU resources to a global pool. Users rent these resources for computational tasks — machine learning, data analysis, inference, training — and the system ensures fair compensation for providers based on the quality and performance of their GPUs through the Bittensor validation mechanism.

- **Providers**: Provide GPU resources, evaluated and scored by validators.
- **Validators**: Securely connect to provider machines to verify hardware specs and performance.
- **Renters**: Rent computational resources through the [lium.io](https://lium.io) platform.
- **Bittensor**: The decentralized blockchain where compensation is managed and paid out in $TAO.
