Aem Integrated Generative Ai Model Provider Abstraction

via “vector embedding generation with provider abstraction”

本项目是一个面向小白开发者的大模型应用开发教程，在线阅读地址：https://datawhalechina.github.io/llm-universe/

Unique: Demonstrates provider abstraction pattern where embedding generation is decoupled from retrieval logic, allowing learners to understand how to swap OpenAI embeddings for local sentence-transformers without rewriting downstream code; includes explicit cost tracking for API-based embeddings

vs others: More educational than production frameworks because it explicitly shows the abstraction layer design; more flexible than single-provider tutorials because it demonstrates how to support multiple embedding backends
