| Hardware
An overview of the hardware configurations available for your CI jobs.
Blaze uses runner tags to specify hardware configurations. These tags are used in the runs-on property of your workflow.
Linux standard jobs use 1 unit for 2 vCPU and 6 GB. The :lg size and compute/ each use 2 units for 4 vCPU and 12 GB; compute/...:lg uses 4 units for 8 vCPU and 24 GB.
macOS
| vCPU | RAM | Runner Tag | Xcode | Units |

| 8 | 24 GB | blaze/macos-26:lg | 26.2 | 2x |
| 4 | 12 GB | blaze/macos-15 | 16.4 | 1x |
| 8 | 24 GB | blaze/macos-15:lg | 16.4 | 2x |

Standard Runners
| vCPU | RAM | Runner Tag | Units |
|---|---|---|---|
| 2 | 6 GB | blaze/ubuntu-22.04 | 1x |
| 4 | 12 GB | blaze/ubuntu-22.04:lg | 2x |
Compute Runners
Compute runners get 4 vCPU and 12 GB for 2x units, the same as the :lg size on the same Apple M2 Macs. The compute/ label is kept so existing workflows keep working.
| vCPU | RAM | Runner Tag | Units |
|---|---|---|---|
| 4 | 12 GB | blaze/compute/ubuntu-22.04 | 2x |
| 8 | 24 GB | blaze/compute/ubuntu-22.04:lg | 4x |
