The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

One of the next improvements is, in general, better training.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

And so IRL is kind of part of it, but IRL is still very spotty.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

In general, AI is like alchemy.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

I don't know if you've read any of the technical papers, but there's like...

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

We're using learning rate of 0.01 until step 10,000, and then we switch to 0.01, and then at 100 million steps, we're going to anneal it at rate 2x.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

It's like, how did you come up with this?

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

Where did this come from?

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

Yeah.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

Well, it's all kind of half made up and half is from experience.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

They were trying to do something.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

It didn't work.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

They were changing a bunch of stuff until it worked.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

And now they're not going to go and redo everything, figuring out if other options work.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

They're just going to keep whatever worked.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

Yeah.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

And so like figuring out how to like go away from that.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

And so RL is even worse.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

RL is like literally, you know, we have no idea, but you know, hopefully like this reward function works, you know, we run it, it works great, you know, ship the paper, ship the model.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

So it's a very like kind of semi-arbitrary.

The Neuron: AI Explained
Illia Polosukhin: Fixing the Broken System He Helped Create

There is no like actual science around reward distribution and kind of reward provocation.
