How deeply does Build AI-Enhanced Web Apps cover abstract factory design pattern?

Explains the specification, factory roles, and stateless-function alternative, but omits detailed client configuration.

Abstract factory design pattern

As explained in Build AI-Enhanced Web Apps

A creational design pattern that provides an interface for creating families of related objects without specifying their concrete classes.

Creates families of related objects through a stable interface while hiding concrete classes. In the Vercel AI SDK, generateText and streamText create language-model instances from different providers. section 3.3.2

The pattern’s implementation has three practical pieces:

A shared language-model specification defines the contract that provider implementations must satisfy. section 3.3.2
A configuration object selects a provider-specific model while preserving the same generateText interface. section 3.3.2
Regular stateless functions can provide the factory behavior; classes are not required. section 3.3.2

Switching providers

Call generateText with openai('gpt-3.5-turbo') or anthropic('claude-v1'), changing the model parameter without changing the text-generation call.
