DeepSeek

Pros
Great for Developers (Excels at understanding and generating code in multiple programming languages.)
Open and Transparent (Offers more openness than many competitors, including access to weights and model details.)
Strong Performance (Reliable for both technical tasks and general-purpose language understanding.)
Active Research Focus (Regular updates and research-backed improvements keep it sharp and relevant.)
Flexible Use Cases (Can be used for coding help, research, technical writing, and more.)
Cons
Less User-Friendly (Geared toward developers, so it may feel technical or barebones for casual users.)
Limited UI Tools (Lacks the polished interface and built-in features of more mainstream AI platforms.)
Still Gaining Recognition (Not as well known yet, which can make support resources and community smaller.)
English-Focused (Best performance is in English—other languages may not be as well-supported.)
Requires Technical Know-How (To get the most out of it, users often need some coding or ML background.)
