Does owning the full chip-to-model stack determine AI leadership?
Core argument: Google's Gemini 3, trained entirely on Google's own TPU chips, is the best-performing model across nearly all dimensions except possibly coding, marking the first time since GPT-3.5 launched three years ago that OpenAI lacks a leading model.
The release of Gemini 3, trained entirely on Google’s own TPU chips, confirms Google’s leading position. Across nearly all dimensions (with the possible exception of coding, as mentioned previously), Gemini 3 is the best-performing model. This marks the first time since the launch of GPT-3.5 three years ago that OpenAI doesn’t have a leading model. Looking ahead, Google has a significant advantage in training frontier models, and efficiently and cheaply servicing them—in part due to its vertically integrated ecosystem. Google has its own large, mature, and competitive hardware stack, from chips to data centers, which likely gives it the cheapest and easiest access to compute among leading AI labs. And after nearly a decade of limiting external access to its TPU chips, Google has also started exploring selling and leasing them to other AI labs and cloud providers in recent months, opening the possibility of it dominating the full AI stack, from chips to models.
