Amazon vs. Google: Two Approaches to Full-Stack AI
Both companies pursue vertical integration, but with different philosophies.
Google’s Approach: Proprietary excellence at every layer. Google builds TPUs (Layer 1), develops Gemini in-house (Layer 2), creates Vertex AI Agents (Layer 3), offers AI-powered tools (Layer 4), embeds AI across Workspace (Layer 5), and distributes through 3 billion+ Android devices (Layer 6). Everything is proprietary, everything is integrated.
Amazon’s Approach: Owned infrastructure, partnered intelligence, governed orchestration. Amazon builds Trainium and Graviton (Layer 1), partners for models while developing Nova (Layer 2), leads in agent governance (Layer 3), deploys specialized tools (Layer 4), proves the model in Connect (Layer 5), and leverages commerce distribution (Layer 6). The stack is more open, more marketplace-oriented.
The Tradeoff: Google’s approach maximizes integration and optimization but requires winning the model race. Amazon’s approach sacrifices some integration for optionality—if Claude beats Gemini, Amazon benefits; if GPT-5 beats both, Amazon still wins.
Where Google Leads Amazon
Google’s vertical integration is tighter at the model layer. Gemini is optimized for TPUs in ways that third-party models on Trainium cannot match. Google can move faster on capability improvements because it controls research, training, and deployment end-to-end.
Google’s consumer reach far exceeds Amazon’s. Search, Android, YouTube, Gmail, Maps—Google touches more humans more frequently than any company except perhaps Meta. This data advantage could prove decisive for model training.
Where Amazon Leads Google
Amazon’s agent infrastructure surpasses Google’s. AgentCore’s governance capabilities—Cedar policy language, real-time evaluation, persistent memory—exceed anything in Vertex AI Agents. Enterprises care about control as much as capability.
Amazon’s enterprise relationships run deeper. AWS has spent two decades building trust with CIOs and CISOs. Google Cloud is growing fast but started later and smaller. When enterprises deploy mission-critical AI agents, trust matters.
Amazon’s commerce data has no equivalent. Google has more data overall, but Amazon has the data that matters for commerce AI—purchase intent, price sensitivity, conversion patterns. For agentic commerce, Amazon’s data advantage is unassailable.
The Vertical Integration Scorecard
- Leads: Agent infrastructure (Layer 3), commerce distribution signal quality (Layer 6)
- Strong: Silicon scale (Layer 1), agent/tool portfolio (Layer 4)
- Adequate: Foundation models via partnerships/marketplace (Layer 2)
- Weakest: Enterprise application breadth (Layer 5)
