The more you tell AI what to do, the more efficient it becomes.
Andy Crestodina and I collaborated on an article about making AI more efficient, and I’m planning on doing a longer, more technical version in my newsletter this weekend that gets into serious nerd territory, but one of the most fundamental tips is that the more concretely you tell AI what to do, the more efficient it becomes.
My cofounder and CEO Katie Robbert talked about this on In-Ear Insights, the Trust Insights podcast last week. We say to humans, “Go to the store and pick up some milk.” As she tells it, we know implicitly that this means go to the store, pick up the milk, take it to the checkout, pay for it, bring it home, and put it in the fridge.
AI doesn’t know that. So it has to think. It has to reason. Don’t believe me? Look at the thinking traces of a reasoning model like Qwen 3.6. In the first test, I told it:
If I say, “go to the store and pick up some milk” what am I saying?
It took Qwen 826 tokens to generate a response.
So I said this:
If I say, “go to the store and pick up some milk” what am I saying? Output your response in plain text in as few words as practical while preserving all relevant information.
Believe it or not, this is even more vague and it took 1,416 tokens to reason through the answer. Why? Because it had to decide what “few” meant, and then run a half dozen scenarios. “Few” isn’t objective and quantitative.
So I give it a concrete, clear outcome:
If I say, “go to the store and pick up some milk” what am I saying? Output your response in plain text in 10 words or less.
This time, it took Qwen only 252 tokens to answer.
This is happening behind the scenes every time we use AI. The more we bring concrete, clear, and defined outcomes, the better AI performs and the more efficient it is. Local AI models like Qwen let us not only test this, but see the exact reasoning and how many tokens different requests consume.
