Interconnects

Technical analysis of frontier AI models and training methods.

Substack Machine Learning Weekly Updated Sep 2026

About

Interconnects, written by AI researcher Nathan Lambert, covers the technical details behind major model releases, reinforcement learning from human feedback, fine-tuning methods, evaluation benchmarks, with the specificity of someone who has actually trained these systems.

It sits closer to research notes than journalism, which makes it dense but valuable for practitioners who want a technically literate take on what's actually new about a given release, not just the marketing.
