It's very necessary to say that your ability to explore the best part of these chat bots is how best you can arrange your questions and prompts, if you know how to generate good prompts, you will get good responses. I have tried DeepSeek too like I tried ChatGPT, and ChatGPT still offers a better interface design and smooth response. DeepSeek may probably be more smarter in giving response at the barest minimal of question twisting and intelligence, but it is still important for DeepSeek to work on their interface to enable easygoing activities particularly in terms of formatting of texts and responses.
You have to spend time in arranging questions and prompt in way that AI chat bot can get idea about what exactly you want to know. It's like asking something from a wise person, the exactness of answer depends on how well you placed your question.
As per my personal experience with DeepSeek since start of February, it has gone up in performance since it's initial launch in Jan 2025. Initially I have seen it crashing on some queries and this issue is very much settled. But for now, ChatGPT is the king in AI chat bot domain because it has an algorithm that's matured over a period of time.
