Cons

Strict content filters can sometimes interrupt conversations unexpectedly, even in non-problematic contexts, which can break immersion and frustrate users seeking creative freedom.
Characters can fall into repetitive response patterns during extended conversations, occasionally recycling similar phrases or narrative structures across sessions.
Since the platform prioritizes personality and engagement over factual accuracy, it should not be relied upon for research, homework, or any task requiring truthful information.

The hosted chat service routes data through servers in China, raising potential data privacy and regulatory concerns for users in regions with strict data sovereignty requirements.
Content moderation on the hosted platform reflects Chinese regulatory requirements, which means certain political, historical, and sensitive topics may receive filtered or limited responses.
While the reasoning model is excellent, the general conversation model can sometimes feel less polished and natural than ChatGPT or Claude in casual, creative, or nuanced dialogue tasks.
