While powerful, Google's TPUs were designed solely for its own data centers. This creates significant adoption friction for external customers, as the hardware is non-standard—from wider racks that may not fit through doors to a verticalized liquid cooling supply chain—demanding extensive facility redesigns.
Despite intense competition, Amazon's core principle of being 'customer obsessed' means AWS would likely provide Google's TPU chips if key customers demand them. This prioritizes customer retention over platform exclusivity in the AI chip wars.
Google's competitive advantage in AI is its vertical integration. By controlling the entire stack from custom TPUs and foundational models (Gemini) to IDEs (AI Studio) and user applications (Workspace), it creates a deeply integrated, cost-effective, and convenient ecosystem that is difficult to replicate.
Model architecture decisions directly impact inference performance. AI company Zyphra pre-selects target hardware and then chooses model parameters—such as a hidden dimension with many powers of two—to align with how GPUs split up workloads, maximizing efficiency from day one.
Major AI labs aren't just evaluating Google's TPUs for technical merit; they are using the mere threat of adopting a viable alternative to extract significant concessions from Nvidia. This strategic leverage forces Nvidia to offer better pricing, priority access, or other favorable terms to maintain its market dominance.
As the current low-cost producer of AI tokens via its custom TPUs, Google's rational strategy is to operate at low or even negative margins. This "sucks the economic oxygen out of the AI ecosystem," making it difficult for capital-dependent competitors to justify their high costs and raise new funding rounds.
Satya Nadella clarifies that the primary constraint on scaling AI compute is not the availability of GPUs, but the lack of power and physical data center infrastructure ("warm shelves") to install them. This highlights a critical, often overlooked dependency in the AI race: energy and real estate development speed.
The infrastructure demands of AI have caused an exponential increase in data center scale. Two years ago, a 1-megawatt facility was considered a good size. Today, a large AI data center is a 1-gigawatt facility—a 1000-fold increase. This rapid escalation underscores the immense and expensive capital investment required to power AI.
The fundamental unit of AI compute has evolved from a silicon chip to a complete, rack-sized system. According to Nvidia's CTO, a single 'GPU' is now an integrated machine that requires a forklift to move, a crucial mindset shift for understanding modern AI infrastructure scale.
Cohere intentionally designs its enterprise models to fit within a two-GPU footprint. This hard constraint aligns with what the enterprise market can realistically deploy and afford, especially for on-premise settings, prioritizing practical adoption over raw scale.
While competitors like OpenAI must buy GPUs from NVIDIA, Google trains its frontier AI models (like Gemini) on its own custom Tensor Processing Units (TPUs). This vertical integration gives Google a significant, often overlooked, strategic advantage in cost, efficiency, and long-term innovation in the AI race.
