The AGI Stack: from chip to application

A new full-stack architecture is emerging—one that spans purpose-built silicon, agentic cloud infrastructure, orchestration frameworks, frontier models, and autonomous applications—to support a fundamentally new class of intelligence.
A Stack for a New Kind of Intelligence
The AI infrastructure conversation has historically centred on GPUs. Data center expansion over the past several years has been driven by the race to deploy more accelerated compute for large-scale model training. But the landscape has shifted. Enterprise AI is entering a new phase, one defined not by single model inference but by autonomous systems that coordinate multiple models, tools, and data sources in real time. Agentic AI workloads are persistent, distributed, and inference-driven. They require systems capable of handling orchestration, retrieval, reasoning, and real-time decision making at scale.
This shift is driving a new wave of infrastructure requirements—and a new full-stack architecture that spans silicon, cloud, frameworks, models, and applications. The AGI stack is being built from the ground up.
Silicon: The New Foundation
At the base of the stack lies a new generation of purpose-built silicon. In March 2026, Arm introduced the AGI CPU, its first system-on-chip for datacenter infrastructure. Built with up to 136 Arm Neoverse V3 cores, 12 DDR5 memory channels, and PCIe Gen6 connectivity within a 300W power envelope, it delivers exceptional compute density and energy efficiency for AI-first data centers. The AGI CPU delivers more than 2x performance per rack compared to traditional x86 CPU deployments, enabling cloud providers to dramatically increase compute density while remaining within power and thermal constraints.
The silicon race extends beyond CPUs. Google debuted two AI processors—the TPU 8t, optimised for training, and the TPU 8i, optimised for inference and AI agents. The TPU 8t offers 2.8x better price-to-performance than its predecessor. Meanwhile, Alibaba unveiled its Zhenwu M890 AI chip, delivering three times the performance of its predecessor. As one executive noted, in the agentic era, an agent executing a task may initiate dozens of model calls in milliseconds, requiring CPU, GPU, network, and storage to work in tight coordination.
Infrastructure: The Agentic Cloud
Above the silicon lies a reimagined cloud infrastructure. Agentic workloads are fundamentally different from traditional cloud workloads: they are "irregularly elastic, short-lived, and instantaneously bursty". Traditional cloud products, designed for human interaction, are being transformed into modular capabilities that agents can "call like functions".
Alibaba Cloud has completed a full-stack agentic upgrade across its "chip-cloud-model-inference" architecture. Arm's AGI CPU serves as the orchestration layer, coordinating inference workloads while offloading model execution to purpose-built accelerators. This separation enables each layer to scale independently. Supermicro has introduced liquid-cooled rack platforms capable of supporting up to 45,696 cores per rack.
Frameworks: The Orchestration Layer
The orchestration layer has matured dramatically. By 2026, AI agent frameworks have become sophisticated: LangGraph supports graph-based orchestration and state recovery; LlamaIndex specialises in RAG and multi-source querying; AutoGen and CrewAI focus on multi-role collaboration. Common capabilities include introspection, dynamic tool calling, multi-level memory, and task planning.
LangChain remains the dominant open-source framework for rapid prototyping, while LangGraph provides stateful multi-agent orchestration. CrewAI enables role-based multi-agent prototypes with an intuitive mental model. The Microsoft Agent Framework unifies AutoGen and Semantic Kernel. Google ADK offers an opinionated runtime for GCP-native teams. The framework you choose determines what you can build quickly; the observability layer determines whether it keeps working.
Models: The Cognitive Core
The model layer has entered the trillion-parameter era. OpenAI's GPT-5 Ultra reaches 10 trillion parameters. Anthropic's Claude 4 introduces neuro-symbolic architecture. Google's Gemini 3 achieves native million-token context. DeepSeek-R1 delivers reasoning capabilities that rival closed-source models at a fraction of the cost. As of May 2026, the most common base models inside LLM agents are GPT-5.x, Claude Opus 4.7, Gemini 3.x, and tool-tuned Llama 4 variants.
Yet the paradigm is shifting. As one industry leader observed: "Large language models are undergoing a core paradigm shift: from aligning with human preferences to aligning with task objectives. In the past, we pursued models that 'speak well'; now we demand models that 'get things done'". The Qwen3.7-Max demonstrated this shift by working autonomously for 35 hours to complete a production-grade AI compute kernel from scratch—without human intervention.
Applications: The Agentic Frontier
At the top of the stack sit the applications—fleet of autonomous agents deployed across industries. Tata Steel deployed over 300 agentic AI systems across its global value chain, from predicting asset maintenance to reducing customer response times. Hexaware launched "Zero License," enabling enterprises to make AI agents the primary execution layer, reducing software license costs and eliminating manual effort. Healthcare AI agents automate claims, prior authorisations, and provider workflows. HCLTech, Google Cloud, and ServiceNow have partnered to deliver enterprise AI agent solutions.
The agentic application paradigm is distinctive. As one executive explained, "agentic apps are made up of teams of agents, each one with their own specialty, and you can give them a business objective, and then they reason and decide how to achieve the objective". This is not automation as we have known it. This is delegation.
A Stack in Motion
The AGI stack is not a static architecture—it is a system in rapid evolution. Silicon is being purpose-built for agentic workloads. Cloud infrastructure is being rearchitected for autonomous, bursty, inference-driven demand. Frameworks are maturing from prototypes to production-ready orchestration. Models are shifting from conversation to execution. Applications are moving from experimentation to scaled deployment.
Each layer of the stack is being transformed, and each transformation accelerates the others. The result is a new kind of infrastructure—one built not for human users clicking buttons, but for autonomous agents reasoning, planning, and executing at machine speed. The AGI stack is the foundation upon which the next era of intelligence will be built.
