Local AI is useful because it gives the workflow a predictable blast radius

Local AI is not valuable because it sounds advanced. It is valuable when a workflow needs predictable cost, data locality, and a controlled failure mode.

The smartest model is not always the right model

A lot of AI architecture starts by asking which frontier model is best. That is sometimes the right question. It is not the only question.

For many business workflows, the repeated work is classification, summarization, routing, and first-draft context prep. Those jobs may not need the most expensive model in the loop.

Why local inference changes the design

When the marginal token is cheap and the data stays on your hardware, you can afford different patterns. You can let the system read more context. You can run second passes. You can process internal queues without worrying that every extra check changes the bill.

That does not mean every workflow should be local. It means local inference gives you another tool for the parts of the workflow that benefit from cost ceilings and data locality.

Good split, bad split

A good split uses local models for bounded tasks and reserves stronger hosted models for judgment-heavy work. For example: local model classifies and summarizes incoming requests; a stronger model handles a complex synthesis only after the human asks for it.

A bad split uses local AI as a magic privacy blanket. If the workflow still writes bad data back into the CRM, or exposes records to the wrong user, running locally did not solve the actual risk.

The operating question

The question I care about is: what is the blast radius when this workflow is wrong?

If the answer is small because the AI drafts only, cites sources, waits for approval, and logs everything, then the workflow can be useful early. If the answer is large because it acts silently, local vs hosted is not the first problem to solve.
