Chinese company DeepSeek has launched test versions of its new top AI model. This comes a year after it caused a stir in Silicon Valley. DeepSeek calls it the most powerful open-source platform. It challenges US rivals like OpenAI and Anthropic.
The AI startup revealed the V4 Flash and V4 Pro series. They claim top performance in coding tests. The models also show big improvements in thinking skills and agent tasks.
DeepSeek stated on Hugging Face that the models have better design. They also have improved performance. This is according to a Bloomberg report.
DeepSeek highlighted a new technology called "Hybrid Attention Architecture." This helps the AI model better remember questions. This is useful in long conversations.
The company also increased the context window size to one million tokens. This allows users to send full databases or long documents in one request.
The V4 models launch over a year after DeepSeek released its R1 model. R1 caused a huge stock market sell-off. This was because it was an open-source model that mimicked human thinking.
R1 competed with advanced AI systems from companies like OpenAI. Reports say it was built at a much lower cost.
DeepSeek said the V4 Pro model beat other open-source models in global knowledge tests. Only Google's closed-source Gemini-Pro-3.1 performed better.
The Flash version is a lower-cost option. The test versions allow DeepSeek to get feedback from real users. The company has not set a date for the final model release.
DeepSeek, owned by China's High-Flyer Capital Management, wants to raise over $20 billion. This is according to a recent report. Giants like Alibaba and Tencent are talking about buying stakes.
DeepSeek has faced controversy. Washington and US rivals have accused it of bad and illegal behavior.
The White House recently accused China of stealing IP from US AI labs. This could increase tensions before a leaders' summit next month.
The Chinese Embassy in Washington called these claims baseless. They said Beijing strongly protects intellectual property rights.
