At a pivotal juncture, as DeepSeek prepares to relaunch its second round of fundraising, a confidential document concerning its equity investment has surfaced on social media platforms. This document not only unveils contentious financial clauses but also inadvertently discloses details about the yet-to-be-announced V4-Pro model. According to the leaked information, the programming prowess of V4-Pro falls short of Claude's flagship model by a mere 0.3%. It boasts a context window supporting up to 1 million tokens, and its API pricing is remarkably competitive, ranging from just one-tenth to one-hundredth of that charged by overseas rivals.
