Hello local ai peoples I need some recommendation

How is the performance of the gpt oss 120b model?

I have a server with 96g of ram and a intel arc in it that should be able to handle it but I'm torn between self hosting the gpt oss or just paying for the GPT-5 API

I know gpt-5 benchmarks higher but how good is oss actually? is it comparable to models like o3?
