Stop Wasting Money: The Smart Way to Use Multiple AI Models for Maximum Results

Plan big, act small has never been more important.

This is Principle 27 in my book, Almost Timeless: 48 Foundation Principles of Generative AI.

In the last month, we’ve had 3 MAJOR foundation model releases: GPT-5.1, Gemini 3, Claude Ops 4.5. These new models are incredibly capable. They’re super smart.

They’re also really compute and money expensive. If you’ve done more than 5 minutes of work with any of them and you’re not paying top dollar for Max/Ultra/Bro plans, you’ve likely hit rate limits/model not available/come back later/pay me more notices.

The top mistake most of us make is using one model for everything, which burns up costly resources on trivial tasks. Instead of thinking of your favorite AI tool as a monolithic interface, a black box with one button, think of it like a consulting firm.

A senior consultant with a big billing rate shouldn’t be doing intern or junior consultant work.

A junior consultant should not be a project lead.

When you go to do a project, be it write a novel, build some code, design a website, etc., think like a manager. Delegate the hardest tasks to the senior consultant (expensive models like Gemini 3 Pro, Claude Opus 4.5, GPT-5.1 Thinking).

Once you’ve got your plan/outline/skeleton/framework, then delegate the implementation to a junior consultant (cheap models like Gemini 3 Flash, Claude Haiku 4.5, GPT-5.1 Mini). You will dramatically increase your productivity and not run up big bills, especially if you are paying as you go. (API vs. subscription)

On top of that, it boosts your AI sustainability footprint. You don’t take a Harrier fighter jet to the grocery store, you take a car (or better yet a bicycle or even walking). Don’t use the biggest models for everything – the smaller the model, the less of an environmental footprint you leave.

Again, think like a manager. Would you have your most expensive lawyer summarizing trial transcripts, or would you have your cheapest paralegal do that?

Plan big, act small.
