Cons

Despite improvements, ChatGPT can still occasionally generate plausible-sounding but factually incorrect information, requiring users to verify critical claims independently.
The free tier imposes usage limits during peak hours, and access to the most advanced models like GPT-4o can be throttled, pushing users toward the paid plan.
Conversation context can degrade in very long threads, sometimes causing the model to forget earlier instructions or details discussed many messages ago.

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.
