On the evening of April 7, 2026, DeepSeek's web and app versions underwent a stealthy yet significant update, rolling out two brand-new modes: 'Quick Mode' and 'Expert Mode'. The Quick Mode is designed with a focus on delivering instantaneous responses, making it an ideal choice for daily conversations. Moreover, it supports image and file text recognition, enhancing user experience in various scenarios. On the other hand, the Expert Mode stands out for its exceptional ability to handle complex issues, ranging from programming and legal consultations to medical inquiries and mathematical logic reasoning. However, during peak usage hours, users might encounter a waiting period. Additionally, it's worth noting that file uploads and multimodal functions are not currently available in this mode. This update could potentially be seen as a precursor to the much-anticipated release of the V4 series models.
