The AI Stack: A Practical Guide to Building Your Own Intelligent Applications
This article provides a practical guide for developers on how to build AI-powered applications by breaking down the process into a four-layer stack: foundation, infrastructure, integration, and application layers.
Why it matters
This guide provides a practical, step-by-step approach for developers to start building their own AI-powered applications, moving beyond just the hype and theory.
Key Points
- 1Modern AI development is about strategically assembling specialized tools, not creating a sentient being
- 2The four-layer AI stack includes foundation (models & APIs), infrastructure (compute & orchestration), integration (tooling & frameworks), and application (UX & business logic)
- 3Developers can leverage cloud APIs, open-source models, or fine-tuned/specialized models as the foundation layer
- 4The infrastructure layer involves compute resources and orchestration tools to run the AI models
- 5The integration layer connects the AI capabilities to the application through frameworks and tooling
- 6The application layer focuses on the user experience and business logic that leverages the AI features
Details
The article emphasizes that modern AI application development is less about creating a sentient AI and more about strategically assembling a set of powerful, specialized tools. It breaks down the process into a four-layer stack: 1) Foundation Layer (models & APIs) - Developers can leverage cloud APIs, open-source models, or fine-tuned/specialized models as the core AI capabilities; 2) Infrastructure Layer (compute & orchestration) - Involves the compute resources and orchestration tools to run the AI models; 3) Integration Layer (tooling & frameworks) - Connects the AI capabilities to the application through frameworks and tooling; 4) Application Layer (UX & business logic) - Focuses on the user experience and business logic that leverages the AI features. The article provides a Python code example demonstrating how to use the OpenAI API for a text summarization feature as part of the foundation layer.
