When does this happen?

IF UnicodeDecodeError on Windows when importing litellm due to JSON file opened with default system encoding instead of UTF-8.

How others solved it

THEN Explicitly specify encoding='utf-8' when opening files known to be UTF-8 encoded, such as cached JSON model cost data, to prevent encoding mismatch on Windows where default encoding is cp1252.

# Instead of: json.load(f)
with open('model_prices_and_context_window.json', 'r', encoding='utf-8') as f:
    json_data = json.load(f)
