notable: they ripped out the silicon that supports training

they say: “it’s the age of inference”

which, yeah, RL is mostly inference. Continual learning is almost all inference. Ambient agents, fast growing inference demands in general audiences

Ironwood's matrix multiply units (MXUs) have been entirely reengineered for inference-only operations with some major differences from training-centric architectures:

Meanwhile on Mars...

The planet is covered with odd gullies that look like they were carved by running water. A cool new experiment demonstrates that they were probably carved by sliding, spitting chunks of dry ice. (Sorry, still no signs of life.) 🧪🔭

I connected my laptop to my piano and typed into the terminal “connect to my piano and play a few notes with midi” and it worked first try. This is some Star Trek shit. If you told me 5 years ago this would be possible today I would not have believed you.

I just saw the Kimi K2 Thinking release!

Kimi K2 is based on the DeepSeek V3/R1 architecture, and here's a side-by-side comparison.

In short, Kimi K2 is a slightly scaled DeepSeek V3/R1. And the gains are in the data and training recipes. Hopefully, we will see some details on those soon, too.

Good morning! Today I plan to continue on from yesterday's tinkering, so if you want to catch up, check the linked post.

I currently have a testable hypothesis: If you initialize a model's embedding matrix to a single random vector, after training the token cloud will look like Qwen 3's. 🧵

After a lot of tinkering, I finally have a good-quality map of the Qwen 3 4B Instruct 2507 vocabulary as taken from the center of the cloud. If you look at the density map you can see the black hole cluster dominating the sky. Mask out the 13 black holes and we find there's still an overdensity.

But I do know that this isn’t sustainable. Abolish ICE. There is no way to reform this.

What was the story about creating Swift - and why did he face resistance inside Apple when wanting to replace Objective C?

It’s awesome to see humanoid bodies developing rapidly alongside AI. More heavy industry manufacturers should be on top of this, as when successful, they’ll be everywhere: factories, homes, etc.
