Passing model as positional argument instead of keyword -> Option B
Quick Check:
Constructor needs keyword args [OK]

Quick Trick: Always use keyword arguments when creating ChatAnthropic [OK]

Common Mistakes:

Using positional arguments for model
Assuming invoke() is undefined
Incorrect message dictionary format
