Compute EngineGenerally available: You can create and use Flex-start VMs. Flex-start VMs are virtual machine (VM) instances that can run for up to seven days, and that use the flex-start provisioning model. This model provisions resources from a secure pool of capacity, increasing your chances of obtaining high-demand resources like GPUs. These features make Flex-start VMs suitable for short-duration workloads that can start at any time, such as the following:
- Small model pre-training
- Model fine-tuning
- High performance computing (HPC) simulation
- Batch inference
You can create standalone Flex-start VMs, or add Flex-start VMs all at once to a managed instance group (MIG) by using resize requests. Based on the machine type that your Flex-start VMs use, you get discounts for vCPUs, memory, and any attached GPUs.
For more information, see About Flex-start VMs.

Compute EngineCompute Engine enforces limits to the total baseline performance that a project's Hyperdisk Balanced and Hyperdisk Balanced High Availability disks that are in the same zone can consume at the same time. The aggregate baseline performance limit is 50 GiB/s of throughput and 500,000 IOPS, and it only applies to baseline performance. For a detailed explanation, see Concurrent consumption limits for baseline performance.
