In my latest post, I quickly review Gemma 4, Google's exciting new open models, but mostly focus on the questions around what makes an open model succeed in the long term.

The core of my answer is that we desperately need to build a field of research on "what makes a finetunable model" if we want the open model economy to succeed. Too much of that research happens behind closed doors of companies.

Plus, 240 days after The ATOM Project was released, I share reflections on the recovery of American models, and what that means.
