# Runner Sizes & Labels (https://tenki.cloud/docs/runners/sizes)

> For the complete documentation index, see [llms.txt](https://tenki.cloud/llms.txt)

Standard Tenki runner configurations with their CPU, memory, and operating system.

Use this reference to choose the complete `runs-on` value for a standard Tenki runner. Pricing, credits, plan limits, and billing are maintained on the [Pricing page](https://tenki.cloud/docs/pricing.md).

Use one Tenki label as the complete `runs-on` value. Arrays that combine it with labels such as `self-hosted` or `linux` aren't supported.

## Linux x64

These runners use bare-metal AMD EPYC hardware; see [Linux x64 Runners](https://tenki.cloud/docs/runners/x64-runners.md) for hardware and image details.
