Personal experience with Deepseek R1: it is noticeably better than claude sonnet 3.5

My usecases are mainly python and R for biological data analysis, as well as a little Frontend to build some interface for my colleagues. Where deepseek V3 was failing and claude sonnet needed 4-5 prompts, R1 creates instantly whatever file I need with one prompt. I only had one case where it did not succed with one prompt, but then accidentally solved the bug when asking him to add some logs for debugging lol. It is faster and just as reliable to ask him to build me a specific python code for a one time operation than wait for excel to open my 300 Mb csv.
