Local versus cloud is a workload question. The wrong route appears on exceptions and busy hours. Keep a safe escape for uncertain cases. #EricFieldNotes
Full written post / accessibility read
A local small model may beat a remote call for repetitive private decisions. A frontier-scale cloud service may win on unfamiliar reasoning and concurrency. Neither statement is universal. The useful split starts with task quality, data boundary, latency, load and recovery.
A local path handles ordinary records quickly, but unfamiliar exceptions need rescue. A cloud path handles them better, but network delay or policy may matter. If the benchmark mixes them into one mean, routing either way can hurt the very cases that matter most.
Pin a specific local model and box and a specific hosted model version. Compare quality, p ninety-five latency, concurrency, data transfer, human rescue, failure recovery and total cost per accepted task for each class. Include cold and warm starts.
Place routine work locally where it passes the contract and privacy matters. Escalate novel or overloaded work to an authorized cloud path, or a person, when that path passes. Do this because a good hybrid system matches the workload, not a branding preference.

Four-beat scene transcript
1. Local versus cloud is a workload question.
A local small model may beat a remote call for repetitive private decisions. A frontier-scale cloud service may win on unfamiliar reasoning and concurrency. Neither statement is universal. The useful split starts with task quality, data boundary, latency, load and recovery.
Visual: Model ownership is only one constraint.
2. One average hides the hard tail.
A local path handles ordinary records quickly, but unfamiliar exceptions need rescue. A cloud path handles them better, but network delay or policy may matter. If the benchmark mixes them into one mean, routing either way can hurt the very cases that matter most.
Visual: The wrong route appears on exceptions and busy hours.
3. Run a paired route table.
Pin a specific local model and box and a specific hosted model version. Compare quality, p ninety-five latency, concurrency, data transfer, human rescue, failure recovery and total cost per accepted task for each class. Include cold and warm starts.
Visual: Same cases and acceptance oracle on both paths.
4. Route by observed fit.
Place routine work locally where it passes the contract and privacy matters. Escalate novel or overloaded work to an authorized cloud path, or a person, when that path passes. Do this because a good hybrid system matches the workload, not a branding preference.
Visual: Keep a safe escape for uncertain cases.
