DeepSeek V4 Launch Next Week Promises 50× Cheaper AI and a Shock to US Stocks

DeepSeek announced that its V4 model will be released next week, positioning it as a native multimodal large language model capable of generating and understanding images, video, and text, and supporting context windows of up to one million tokens.

The model is distinguished by a strategic shift: instead of optimizing for Nvidia GPUs, DeepSeek has performed deep tuning for domestic Chinese AI chips, signaling a move from "using foreign chips to run our models" to "using our own chips to run our models".

According to leaked information, DeepSeek V4 Lite (code‑named "Sealion‑lite") already offers a context window of one million tokens and outperforms the previous V3.2 model in quality even without the "thinking" mode. A publicly shared comparison image shows V4 Lite producing higher‑quality SVG output than the V3.2 "thinking" model.

Community members claim that V4’s coding performance may surpass current GPT and Claude models, and that its API pricing will be more than fifty times cheaper than competing services.

Unlike previous flagship releases that were tightly coupled with Nvidia hardware, DeepSeek deliberately avoided early access to Nvidia’s chips for V4, breaking a long‑standing industry practice of performance‑first optimization on Nvidia GPUs. This "reverse operation" is highlighted by Reuters and the Financial Times.

The article revisits the impact of DeepSeek’s earlier R1 release in January 2025, which caused Nvidia’s stock to plunge 17% (about $5.9 trillion in market value) and sparked a wave of market anxiety about AI infrastructure spending.

A detailed timeline outlines DeepSeek’s rapid development from its founding in July 2023 through successive model upgrades (V3‑0324, R1‑0528, V3.1, V3.2‑Exp, DeepSeekMath V2, and research papers on Manifold‑Constrained Hyper‑Connections and Engram memory), culminating in the upcoming V4 launch in March 2026.

Analysts and investors question whether the lower training and inference costs of a Chinese‑optimized model will diminish the justification for the hundreds of billions of dollars that US tech giants invest in AI infrastructure each year.

External commentary includes a venture capitalist calling DeepSeek’s breakthrough "one of the most impressive" and several US tech figures likening the event to the 1957 Sputnik moment, emphasizing the geopolitical significance of China’s AI progress.

Overall, the article argues that DeepSeek V4 represents not just a technical upgrade but a strategic realignment of AI development toward architecture innovation and resource efficiency, with potentially profound effects on the global AI market.
