About US AI Academy
US AI Academy is an independent online academy, founded by Jazon Samillano, an American AI engineer. The courses open AI up: you follow a real model one step at a time, with real numbers you can change yourself.
Every number is real; every lesson is hands-on.
Founder and AI InstructorHow the courses are made
Every lesson follows the same four rules. Each one comes with a place in Course 1 where you can see it for yourself.
The examples come from real runs of real AI models, never made-up values, and they’re checked before they go in a lesson.

Qwen3-0.6B-Base, a small open AI model from 2025, reads “The Eiffel Tower is in the city of” as 10 pieces of text and guesses Paris with a chance of 63.3%. The course works that number out step by step.
Most lessons have labs: drag a line, turn a dial, change a number, and watch the math respond right away.

The first lesson, The puzzle, hands you a straight line to drag. Your job: both cats on one side, both dogs on the other. Spoiler: you can’t, and the lesson proves why.
Every term is explained where it first appears, so you never have to read a sentence twice. No math degree needed: if you can multiply and add, you can follow every step.

Every symbol in the course, said out loud in plain words, on one page. The only gear you need is a scientific calculator, and the one on your phone will do.
Some things about AI are settled, and some are still being argued about. The courses tell you which is which, instead of smoothing over the gaps.

I trained the same tiny network (three artificial neurons) on the cats-and-dogs puzzle 1,000 times, each time starting from different random numbers. 272 runs got stuck without solving it. The lesson What the math can’t explain yet digs into why that matters.
Who it’s for
You use AI and want to know what’s going on inside it, explained in plain words, without a math degree.
You want to work in AI, or next to it, and you want the basics to actually make sense, not just sound familiar.
You’d rather redo the math than take anyone’s word for it. Every number comes from a real run, so you can.
