DeepSeek Launches V4 Model With Drastically Reduced Costs

Chinese AI startup DeepSeek released its new DeepSeek-V4 model on Friday, boasting an ultra-long context window and drastically reduced compute and memory costs. The release comes over a year after the company shocked the tech world with its low-cost R1 reasoning model. The launch arrives amid escalating US-China tensions over AI, with the White House accusing Chinese entities of large-scale efforts to steal American AI technology. DeepSeek first gained global attention in January 2025 when its generative AI chatbot challenged assumptions of US dominance in the sector.
