In China’s domestic large model sector, DeepSeek V4 is undoubtedly one of the most highly anticipated releases in recent months. Since the launch of its test version in February, users have been eagerly awaiting the official release.
Coupled with a recent surge in system crashes and anomalies, the market speculates that these may be stress tests ahead of the new version’s rollout, with a full launch expected as early as this month. A recently surfaced screenshot from a gray-scale test has further fueled expectations of a major upgrade.

A well-known programmer on Chinese social platform Weibo, @Yigongchang, on Tuesday shared a screenshot of DeepSeek’s updated interface. Unlike the current version, which features the familiar dual options of Deep Thinking (R1) and Smart Search (online), the new interface clearly shows three additional modes: Fast, Expert, and Vision.
This shift signals a redesign of the interaction logic and points directly to a more segmented product lineup. Analysts believe the Fast mode may correspond to a lightweight model, while Expert is likely tied to a deep-reasoning model.
