HONG KONG — DeepSeek, the Chinese artificial intelligence startup that shook world markets last year, launched preview versions of its latest major update Friday as the AI rivalry between China and the U.S. heats up.

DeepSeek’s V4 has been keenly anticipated by users looking to test how it compares to U.S. competitors like OpenAI’s ChatGPT, Anthropic’s Claude and Google’s Gemini. Anthropic and OpenAI have accused DeepSeek of unfairly building its technology off their own.

Some industry analysts had expected the new model to arrive more than two months earlier at the start of the Lunar New Year.

DeepSeek says the new V4 open-source models, which include “pro” and “flash” versions, have big improvements in knowledge, reasoning and in their “agentic” capabilities – the ability to perform complex tasks and workflows autonomously. Another big change is they are supported in part by computer chips made by Chinese tech giant Huawei, reducing DeepSeek's reliance on U.S. chipmakers like Nvidia.

V4 is a successor to V3, an AI model that DeepSeek released in late 2024.

But it was DeepSeek’s specialized “reasoning” AI model, called R1, that took markets by surprise with its release in January 2025. DeepSeek claimed it was more cost-effective than OpenAI’s similar model and it became a symbol of how China was catching up with the U.S. in technological advancements.

DeepSeek said the “V4 Pro Max” version has “superior performance” in terms of standard reasoning benchmarks relative to OpenAI’s GPT-5.2 model and Google’s Gemini 3.0-Pro. It falls “marginally” short of GPT-5.4 and Gemini 3.1-Pro, it said. DeepSeek's release came hours after OpenAI released its new GPT-5.5 model on Thursday.

In terms of “agentic” capabilities, the Chinese company said the V4 “pro” version could outperform Claude’s Sonnet 4.5 and approaches the level of Claude's Opus 4.5 model based on its own evaluation.

The “flash” version of V4 performs on a par with the “pro” version on simple agent tasks and has reasoning capabilities closely approaching it, DeepSeek said.
