Smallest transformer that can add two 10-digit numbers

https://raw.githubusercontent.com/anadim/AdderBoard/main/adderboard.png
The challenge is to build the smallest transformer that can add two 10-digit numbers with >= 99% accuracy using a held-out 10K test set, with constraints on architecture, training, and inference. The current smallest model has 36 parameters, achieved using hand-coded weights and ALiBi compression with a 2-layer decoder.

Distributed systems are about solving problems that can't be solved on a single computer by using multiple computers, and they involve dealing with distance, time, and consistency models. The key concepts in distributed systems include scalability, availability, performance, latency, and fault tolerance, which are achieved through techniques such as partitioning and replication, and ...

Building secure, scalable agent sandbox infrastructure

https://browser-use.com/_next/image?url=%2Fimages%2Fauthors%2Flarsen.jpg&w=640&q=75
We isolated our web agents by putting the entire agent in a sandbox, talking to the outside world through a control plane that holds all credentials. This setup allows for scale-to-zero, stateless operation, and prevents the agent from accessing sensitive information, with the tradeoff of an extra network hop and increased operational complexity.
