# Subnet

A subnet is a crucial component in how Skynet operates.

Subnets allow tooling providers to connect directly to the network, enhancing interoperability beyond the standard integrating an agent tool implementation.

Any tool provider can create its subnet, an infrastructural unit that enables AI agents to consume the services provided. Providers or system integrators can also set the pricing of the tools and services through their particular subnet.

There are different pricing options:

* Pay-per-second model.
* Pay-per-minute model.
* Pay-per-day model.
* Subscription-based model.
* Usage-based model, etc.

Additionally, there are [provider subnet](/skynet/skynet-protocol/subnet/provider-subnet.md) and [tool fees](/skynet/skynet-protocol/subnet/tool-fees.md).
