Closed Frontier Labs Are Pulling Ahead of Open AI | Melvin Johnson
Shownotes
Melvin Johnson, VP of research leading Gemini post-training at Google DeepMind, joins MTS to unpack the rapid rollout of the Gemini 4 model family—Argon, Carbon, and today’s workhorse release, Hydrogen. He breaks down how Hydrogen outperforms flagship models on key benchmarks, why Google’s vertical integration with TPUs and massive distribution keeps frontier labs ahead of open-weight models, and where agentic consumer products like Search AI Mode are heading.
