DeepSeek on Friday released a preview of its V4 large language model, the Hangzhou-based startup's most powerful to date, with 1.6 trillion parameters and a 1 million token context window. The model is the first major frontier release optimized for Huawei's Ascend AI processors rather than Nvidia hardware, and it arrived on the same day Reuters reported that the U.S. State Department had sent a diplomatic cable to embassies worldwide instructing staff to warn foreign governments about alleged IP theft by DeepSeek and other Chinese AI firms.
V4 comes in two variants: V4-Pro, the flagship, which costs $3.48 per million output tokens, and V4-Flash, a smaller 284 billion parameter version, which costs $0.28. OpenAI currently charges $30 per million output tokens for GPT-5.4, and Anthropic charges $25 for Claude Opus 4.6. DeepSeek, however, acknowledges V4 “falls marginally short” of those closed-source models by roughly three to six months of development, but outperforms every other open-source competitor in agentic coding and reasoning benchmarks.
