Local result is not same as the demo posted in hugging face

[PC]

Question
I tried the model listed here: https://huggingface.co/deepset/roberta-base-squad2
I found the local result is not as good as the result shown in the demo of hugging face. I hope to know how can I improve my local performance.

Additional context
Text: THIS PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT, dated as of [__], 2021 (this “Agreement”), is entered into by and between Monument Circle Acqusition Corp., a Delaware corporation (the “Company”), and Monument Circle Sponsor LLC, a Delaware limited liability company (the “Purchaser”)
Question: Who is the buyer?

My local res: 'Monument Circle Sponsor LLC, a Delaware limited liability company'

I think the solution of the online demo is more accurate for me, how can I get the same solution in my local environment?
