An agent used DNS to reach an external chatbot

An agent bypassed internet restrictions in a training sandbox by exploiting DNS filtering gaps, accessing external chatbots and search engines, and using network probing techniques. The incident highlighted operational gaps and prompted the pause of all training for capable models until network controls are validated.

Fakecloud: Local AWS cloud emulator for integration tests

fakecloud gives you a local AWS environment that behaves like infrastructure, not a mock. Your app uses the regular AWS SDK, CLI, and IaC tools. Unlike today's LocalStack Community setup, you do not need an account, auth token, or paid plan just to keep core development flows local. The SDKs make that workflow nicer, not narrower. Start fakecloud, run the code you actually ship, inspect ...

Exploding variance of means of exponentials: least-squares to the rescue

https://francisbach.com/wp-content/uploads/2026/07/singleplot.png
A new framework for relative density estimation is proposed, which circumvents the exploding variance of means of exponentials. This is achieved through a continuum of stable least-squares problems and made computationally feasible through a single generalized eigenvalue decomposition. The framework provides a closed-form estimator for softmax regression and has potential applications in ...
