API vs LangChain
When working with language model APIs (like OpenAI, Anthropic, or others), you can interact with them either directly via their HTTP APIs or indirectly by using a framework such as LangChain. Here are the main differences:

For an extensible chat application where users can choose different AI models (e.g., Gemini, OpenAI, and more in the future), a structured approach using Abstract Base Classes (ABCs) and the Factory Pattern is highly effective. This allows you to define a common interface for all AI providers and easily plug in new ones without modifying existing core logic.
Hugging Face provides a simple and efficient API to access and interact with a wide variety of pre-trained machine learning models. You can use these models for tasks like text generation, sentiment analysis, translation, and more, directly from your application via HTTP requests.
