Which work is suitable?

Anything with nobody waiting: overnight enrichment, classifying a backlog, generating catalogue text, summarising the previous day. Most organisations have more of this than they realise, because it is usually run request by request purely because that is how the first version was written.

What does it actually cost us?

An afternoon of redesign rather than any loss of quality. The process has to submit work, carry on, and handle results when they land, including the ones that failed, and a pipeline that skips the last part loses work without anybody noticing.

Is it worth it for small volumes?

Usually not. The saving scales with the work and the redesign is a fixed cost, so a job running over a handful of items rarely repays the effort, while the same job running nightly over thousands changes the arithmetic completely.

Glossary

Batch processing

Sending work in bulk to be completed when capacity allows, in exchange for a lower price than asking for each answer immediately.

In plain terms

Handing over a pile of work and collecting it later, instead of waiting for each piece. It costs less because you have given up the right to have it now, and the awkward part is redesigning whatever was expecting an immediate answer.

Why it matters

Because a large share of what organisations run through these tools has no reason to be immediate, and is immediate only because that is how the first version was written. Recognising which work those are is one of the few cost reductions available that costs nothing in quality.

How it works

You are selling back the right to have it now. That is the entire trade, and it is why the saving exists: your work fills capacity that would otherwise sit idle between other people's urgent requests.

The answer is the same one. Nothing about the quality changes, which distinguishes this from the other ways of spending less, most of which involve a smaller model or a shorter prompt and a corresponding drop in what you get.

The cost is asynchrony rather than money. A process built around an immediate reply has to become one that submits work, gets on with something else, and handles results when they arrive, which is a genuine redesign rather than a setting.

That redesign is where the failures live. Results arriving later need somewhere to go, somebody to notice they arrived, and a defined behaviour for the ones that failed, and a pipeline missing any of those loses work silently.

The candidates are easy to spot once you look. Overnight enrichment, classifying a backlog, generating descriptions for a catalogue, summarising yesterday's conversations: none of those has anybody waiting, and all of them are commonly run one request at a time because that is how the script was first written.

Volume is what makes the redesign worth it. On a handful of items the saving is not worth an afternoon's work, and the calculation changes sharply once the same job runs over thousands of items every night.

What changes and what does not

Failure handling is the item to dwell on, because it is the one that turns a cost saving into an operational problem months later. When a request is made and answered immediately, a failure is visible: something did not come back, and whatever was waiting notices. When a batch of work is submitted and collected later, a failure is a gap in a set that somebody has to be looking for, and the natural way to write the collection step is to process what arrived. That code is correct, passes every test, and silently drops whatever did not come back. The fix is small and has to be deliberate: count what you sent, count what returned, and make the difference somebody's problem rather than nobody's. Everything else about this trade is favourable. It is rare to be offered the same answer for less money, and the only reason it goes untaken is that nobody has separated the work that needs an answer now from the work that merely gets one.

Common misconceptions

People assume

It gives a worse answer for less money.

In fact

The answer is the same. What you have given up is immediacy, which makes this unusual among cost reductions, because most of the others trade quality away and this one trades away a property much of the work never needed.

People assume

It is a setting to switch on.

In fact

It changes the shape of the process around it. Submitting work and handling results later requires somewhere for them to land, somebody to notice, and a rule for failures, none of which exists in a design that expected an immediate reply.
