How Computer-Use Agents, Embeddings, and DLMs Work
Plus an Embedding Cache deep-dive and the Sakana Fugu report, decoded
Five new blogs this week, covering agents, embeddings, a new way to generate text, and a fresh research report.
Let’s get started.
How do Computer-Use Agents work?
A computer-use agent is an AI program that can operate a computer the way a human does. It looks at the screen, moves the mouse, clicks buttons, and types on the keyboard.
Every computer-use agent runs on one simple cycle, the perceive, think, act loop:
Perceive: Look at the current screen.
Think: Decide the next single action.
Act: Perform that action on the computer.
The beauty of this idea is simple. If a human can do a task by looking at the screen and using the mouse and keyboard, the agent can do it too, without any special doorway into the app.

How do Image Embeddings work?
An image embedding is a list of numbers that represents the meaning of an image.
In simple words, we take an image, and we convert it into a list of numbers. That list of numbers captures what is inside the image.
The most important point is this: two images that look similar in meaning will have embeddings that are close to each other. So the embedding of one cat photo will be close to the embedding of another cat photo. But the embedding of a cat photo will be far from the embedding of a car photo.
This is the whole magic of image embeddings. Similar images give similar numbers. Different images give different numbers.

How does an Embedding Cache work?
An Embedding Cache is a place where we store embeddings we have already computed, so that the next time we need the embedding for the same text, we grab the stored one instead of computing it again.
In simple words, an Embedding Cache means: compute the embedding once, then reuse it.
Computing an embedding costs real money and real time. So an Embedding Cache makes our application cheaper and faster at the same time, without changing the quality of the results. The embeddings are exactly the same numbers we would have computed. We just avoid computing them more than once.

How do Diffusion Language Models (DLMs) work?
A Diffusion Language Model is a type of AI model that writes text by starting from a piece of pure gibberish and slowly cleaning it up into a clear, meaningful sentence.
In simple words, it does not write a sentence one word at a time from left to right. Instead, it starts with a rough, messy version of the whole sentence and then refines it again and again until it becomes correct.
The big difference is that it can fix many words in parallel, instead of one at a time.

Decoding Sakana Fugu Technical Report
Sakana Fugu is a family of AI models. A Fugu model does not answer your question by itself. Instead, it reads your question and decides which other powerful AI models should work on it, how they should work together, and how to combine their answers into one final reply.
In simple words, Fugu is a conductor. A conductor does not play any instrument. The conductor reads the music, decides which musician should play, when, and how loud, and turns many players into one beautiful performance. Fugu does the same thing with AI models.
And here is the most striking part. On many hard tests, Fugu-Ultra beats every model it uses. By combining them well, the team can be stronger than any single member.
