DeepSeek V4 AI Model Released with 1.6 Trillion Parameters, Challenges US Tech Giants Despite Performance Gap

About this episode

DeepSeek released its V4 AI model with 1.6 trillion parameters, challenging US tech giants despite performance gaps.

Chinese artificial intelligence startup DeepSeek released its highly anticipated V4 large language model on Friday, marking its most significant update since a previous release that shook global tech markets over a year ago. The new model features 1.6 trillion parameters and represents the company's first new-architecture model since January 2025. DeepSeek designed V4 as an open-source system, meaning listeners can download, use, and modify it freely. The company claims the model rivals leading closed-source American systems from Anthropic, OpenAI, and Google on major benchmarks while outperforming other open-source competitors. However, according to analysis from the Council on Foreign Relations, V4 does not match the performance of frontier U.S. models. The technical documentation shows V4's reasoning capabilities trail state-of-the-art frontier models by approximately three to six months, with the model explicitly acknowledging it falls short of OpenAI's GPT-5.4 and Google's Gemini 3.1-Pro. Despite this gap, V4 contains significant engineering achievements. The model features a hybrid attention architecture enabling a one-million-token context window at a fraction of the…
