Inside Anthropic: How Claude Actually Gets Built | Alex Albert

Inside Anthropic: How Claude Actually Gets Built | Alex Albert

Author: Peter Yang May 17, 2026 Duration: 35:03

Alex is a research PM at Anthropic building the next Claude model. He gave me a rare inside look at how the research team operates — including how they turn user feedback into model training, how they decide which capabilities to prioritize, and how they improve Claude’s personality. If you’re wondering how frontier model development actually works, then this interview is a must watch.

Alex and I talked about:

(00:00) How Anthropic treats each new model as a product

(04:58) Building adaptive thinking into Claude

(07:07) Why Claude is starting to dream

(11:15) "If it's not a one-way door, then it's essentially free"

(15:40) How Alex uses Claude Cowork to pressure test his docs

(17:05) Inside Anthropic's eval process for new models

(21:02) How Anthropic trains Claude's character

(32:39) The consciousness question Anthropic is quietly working on
