Who it is for
For anyone who wants far better answers from today's 'thinking' AIs and is ready to hand them problems the way those models solve them.
Foundations / Intermediate
Think Like a Reasoning Model
Get far better answers from today's 'thinking' AIs by handing them problems the way they actually solve them.
The problem
It starts with the situation you're actually in.
You get a clear, hype-free picture of how today's reasoning models—like OpenAI's o-series and DeepSeek R1—break a problem into intermediate chain-of-thought steps before answering, and why that differs from both standard chatbots and human thinking.
The answer lands in your inbox with the confidence of a closing argument. A reasoning model has recommended you cut the underperforming product line, and the trace looks airtight: revenue down three quarters running, margin below the portfolio average, a competitor exiting the same segment.
Outcomes
What you'll be able to do.
The five-second decision before every prompt
You face two doors. Behind one is a fast standard model that answers in a second or two—and you learn to choose the right door before you type.
The prompt that strangled its own answer
You hand a reasoning model a real problem—build an internal analytics dashboard or buy one—framed well, with a clear goal, three constraints, the budget, and the timeline.
The second answer is where the work starts
You ask a reasoning model whether to shift half your paid-search budget into paid social, and the logic comes back tidy. You learn why that first answer is only the start.
Match the workflow to the problem's shape
You have the moves. Each was drilled in isolation, on small problems, so the mechanics stayed visible—now you fit them to the shape of a real problem.
Inside the book
A closer look at the work inside.
Map your own work
Pick five tasks you handed to AI last week. For each, ask: how many dependent steps did the correct answer need—one, or several? Could you check the working if the model showed it, or only judge the final tone? And if it were wrong and you acted on it, what would it cost?
The answer is the last step, not the only step checklist
- How many dependent steps did the correct answer require—one, or several?
- Could you check the working if the model showed it, or only judge the final tone?
- If the answer were wrong and you acted on it, what would it cost?
The same problem, two machines
You're deciding whether to consolidate three regional shipping vendors into one. You have per-region volumes, current rates, a proposed blended rate, a one-time migration cost, and the switching risk if the new vendor underperforms in a region. Asked "should we consolidate?", a standard model returns a fluent paragraph of pros and cons.
Build your personal routing rule
Do this with real tasks, not hypotheticals. First, list 8–10 tasks you actually hand an AI in a normal week—be specific: "summarize a meeting transcript," not "writing." Then score each on the three criteria, using the table.
The five-second decision before every prompt checklist
- You wait 30 seconds for a one-line factual answer you could have checked yourself.
- You ask a thinking model to brainstorm taglines and get over-justified, hedged options instead of quick, varied ones.
- You route a high-volume, low-stakes batch job (tagging 500 tickets) through a slow model and pay for thinking on each one.
