Hello Reader,
Deepseek v3 is an open source AI model that is challenging OpenAI's dominance. I decided to give it a spin and provide it a one off prompt in Cursor (which now has Deepseek v3 as one of it's available models) to create a python script with a GUI to download onion links. According to the publicly available testing Deepseek v3 is matching in chain of thought functionality with o1 and is considerable cheaper to run.
I will say the code it wrote is good and its ability to correctly explain and define things works very well. I need to determine what the context window Cursor is making available for this so I can find out how much code I can provide.
Here is the code I got deepseek to write in just a few prompts:
