Time for a link roundup!

New Models

First, some articles on newly released (or not) models:

Sign of the future: GPT-5.5 - Looks like GPT-5.5 caught up with (or maybe passed) the Opus models for coding. The examples gallery is fun and shows how different models handle the following prompt: “build me a procedurally generated 3D simulation showing the evolution of a harbor town from 3000 BCE to 3000 AD, it should look beautiful and allow me to have some control over it”
Anthropic’s Project Glasswing — restricting Claude Mythos to security researchers - Lots of news about Mythos, Project Glasswing and just AI-related security stuff in general. This video from Hank Green is a nice semi-technical overview: You Actually Do Need to Understand Mythos
You’re Paying $200/Month for AI. The Same Models Are Now Free. - Semi-related to the new models, I read a few interesting articles comparing frontier models to open source alternatives. Title here is a little bit click-baity, but article is interesting. This note from Dwarkesh discusses similar topics. His interview of NVIDIA CEO Jensen Huang is also worth a listen.

Quick hits around best practices:

Agent Skills - Skill Library #1
Agent Skills Specification - Skills framework/best practices
Headless everything for personal AI - Importance of strong APIs for agents
Agent Interview Best Practice - This whole Hacker News thread (and the original post from Willison) was all interesting, but the linked comment around having your agent interview you stood out for me.

Sam Altman May Control Our Future - Can He Be Trusted? - A long New Yorker profile on Altman. Not technical, but an interesting read.
