Yesterday: Read my 3 year old Oh, The Places You’ll Go!

3 yo, today: I don’t want to go to school. I want to go to cool places. I WANT TO GO TO COOL PLACES!!!

A great learning experience has a sense of flow. Having a tutor take 5-6s to respond kills that.

Switching to @wafer_ai for inference made Brilliant’s tutoring sessions feel fluid and fun again, and every session metric improved along with that.

i grew up in Mexico, where it wasn’t always easy to find really high-quality educational resources that pushed me intellectually.

i knew pretty early that i wanted to eventually go to one of the best universities i could in the US, and i spent a lot of time trying to get sharper on my own.

@brilliantorg was a very meaningful part of that.

i still remember being in early high school and absolutely spamming their logic courses. i loved them. they genuinely made me better at thinking, especially around math and logic, and helped build a lot of the skills that eventually got me where i wanted to go.

so there is something very surreal about @wafer_ai now serving Brilliant :)

their AI tutor, Koji, needs to respond incredibly quickly while students are working through math and coding problems. before Wafer, Brilliant was speculatively prefetching AI-generated responses so students wouldn’t have to wait.

on our dedicated GLM-5.2 endpoint, they’re now getting ~250ms time to first token and 300+ output tok/s, 3x the throughput of their previous provider!

that let them remove the prefetching layer entirely and cut inference costs by 50%.

it’s hard to describe how gratifying it is to help power a product that helped me become a better thinker when i was a kid.

very full circle moment.

5 yo math circle #11.

This time we made it very hard for them, with 2 tasks.

It was an hour of watching them truly struggle – and eventually, discover new mathematical superpowers.

The materials and instructions are simple, so you can try this at home.

Here’s what we did 🧵

I've been running an informal math circle for preschoolers, and it's amazing what 5 yo's can do.

Combinatorial reasoning, backward induction, beginnings of proof... the concepts are there even before mastering arithmetic.

If you have kids 5-7 you can try these games at home too.

Here's what we did our first session 🧵
