China's DeepSeek releases preview of long-awaited V4 model as AI race intensifies - CNBC

DeepSeek released a preview of its V4 large language model on April 24, 2026, according to a CNBC report. The model is open source, allowing developers to download and modify the code, and positions itself as a strong open-weight competitor to proprietary frontier models. The preview includes benchmark results showing improvements in math and reasoning capabilities, though detailed third-party evaluations are not yet available. The model is released during escalating US-China AI competition, with policymakers from both countries balancing security concerns in the benefits or geopolitical strengthening discussed by their reports as they evaluate further competitive placement.
