Show HN: I trained a 125M model to autocomplete piano on-device(simedw.com)
I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15).

The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device.

The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Is this HN? Aren't people supposed to tinker with tech for no reason other than seeing if they can? Is everything that involves a transformer now just AI BAD? Is that what the world has devolved into? Each side screaming "Orange Man Bad" and endless variations at each other?

It is tiring to read these people. It feels like nothing will please them, but their own ideas, work, methods.

>orange man bad

You know, I was nodding along until you shoehorned that one in.

It's just an example of something people get worked up about, calm down.

I’m plenty calm, I was just stating an objection. I don’t know where you’re getting the idea that I am not.

While it is a neat parlor trick, a lot of people have specific grevience against the application to art. AI has only served to further disempower artists broadly, and arguably it pushes "art" to a lower common denominator. Try to actually situate yourself in "why" people get rankled instead of making it a thought terminating cliche.

Given the AI crowd is very loudly telling us since years how humans will be replaced by LLMs and we will all be poor and left behind if we don’t join their cult, I think it’s a perfectly reasonable reaction. Anything with AI mixed with Art or other human experience is suspicious.

Also, yes, the orange fascist who attempted to coup his way to power, raped women, and is destroying democratic institutions is indeed bad.

No they haven’t. It’s like two guys that nobody really believes. You specifically seek that information out to get mad, then proceed to see it where it’s not. Like when someone makes a cool personal project about their hobby and it happens to involve AI.

I’m not mad and have nothing against the project.

> No they haven’t. It’s like two guys that nobody really believes.

It’s the entire leadership of the AI industry, in case you haven’t noticed

Oh no, AI will take our jobs??? FUCKING LET IT!

Who even wants to do all these jobs if we don't HAVE to??

Ask politicians to give us UBI.

You want to attack the shit that could make shit easier instead of attacking the 200 year old institutions in place that ensure class divisions and perpetual debt and wage slavery? Smart buggers

I have bad news for you if you think that will improve with the current deployment of AI. You will also notice I didn’t mention anything about jobs

  What is the goal here?
To eventually prove that Intelligence™ and Creativity™ isn't special?

Or maybe there is some other "spark" deeper within?

When everyone can make anything as soon as they think of it, what will set us apart?
