DeepSeek Login – DeepSeek Account Sign Up and Sign In

For years, the AI industry operated under the assumption that developing advanced language models demanded massive resources—billions in funding and elite technical expertise. This belief drove the U.S. government to launch the $500 billion Stargate Project, a public-private initiative aimed at securing American dominance in next-gen AI.

But in January 2025, Chinese AI firm DeepSeek shattered this narrative. On January 20, 2025, the company open-sourced its cutting-edge R1 large language model (LLM), offering it free to the public at a fraction of the cost of competitors like OpenAI and Google. The DeepSeek Login R1 model matched—and in some benchmarks surpassed—the capabilities of proprietary Western counterparts.

The disruption escalated days later when DeepSeek’s AI assistant, a mobile app leveraging the R1, rocketed to the top of Apple’s App Store, dethroning ChatGPT. Investors reacted swiftly: on January 27, 2025, U.S. stock markets plunged as shares of AI giants like Nvidia, Microsoft, Meta, Oracle, and Broadcom nosedived. Analysts warned that DeepSeek’s open-source strategy could permanently undercut the profitability of closed, subscription-based AI ecosystems.

What is DeepSeek?

DeepSeek, an AI development company headquartered in Hangzhou, China, was founded in May 2023 by Liang Wenfeng, a Zhejiang University alumnus. Liang also co-founded High-Flyer, a Chinese quantitative hedge fund that owns DeepSeek. While operating as an independent AI research lab under High-Flyer’s umbrella, DeepSeek has not publicly disclosed details about its funding or valuation.

The company specializes in open-source large language models (LLMs), launching its first model in November 2023. Over the next two years, it iterated on its core LLM, achieving global prominence in January 2025 with the release of its DeepSeek R1 reasoning model, renowned for advanced problem-solving capabilities.

Beyond its AI models, DeepSeek offers a suite of tools, including a user-friendly web interface, mobile app, and developer-focused API access, catering to both enterprises and individual users.

DeepSeek vs Open AI ChatGPT

DeepSeek represents the latest challenge to OpenAI, which established itself as an industry leader with the debut of ChatGPT in 2022. OpenAI has helped push the generative AI industry forward with its GPT family of models, as well as its o1 class of reasoning models.

While the two companies are both developing generative AI LLMs, they have different approaches.
