LangChain - LLM and Chat Model Integration

Why does Langchain use interfaces or base classes for models?

ATo reduce the size of the AI model files.

BTo enforce a consistent way to interact with different AI models.

CTo store user data securely within the model.

DTo make the models run in parallel automatically.

Step-by-Step Solution

Solution:

Step 1: Understand purpose of interfaces/base classes
Interfaces define a common set of methods all models must have.
Step 2: Connect to Langchain model abstraction
This ensures code can call any model the same way, improving flexibility.
Final Answer:
To enforce a consistent way to interact with different AI models. -> Option B
Quick Check:
Interfaces = Consistent model interaction [OK]

Quick Trick: Interfaces ensure all models behave the same way [OK]
