DeepSeek

DeepSeek is a Chinese AI research company founded in 2023 as a subsidiary of High-Flyer, a quantitative hedge fund. Based in Hangzhou, the company made global headlines in January 2025 when it released DeepSeek-R1, a reasoning model that matched or exceeded the performance of leading US models at a fraction of the reported training cost. DeepSeek's first outside venture round, reported in June 2026, is raising approximately 50 billion yuan (about $7.4 billion) at a valuation of $52 to $59 billion, led by Tencent and battery maker CATL — with founder Liang Wenfeng contributing a large share of the round himself and the state-backed National Artificial Intelligence Industry Investment Fund among the parties in discussions. The raise places the lab alongside frontier US labs by valuation even though its training spend remains a fraction of theirs.

DeepSeek's current flagship lineup is V4-Pro (1.6 trillion total / 49 billion active mixture-of-experts) and V4-Flash (284 billion total / 13 billion active) — both MIT-licensed with 1 million-token context windows. V4-Pro is the largest open-weights model ever released and uses roughly 27% of V3.2's FLOPs and 10% of the KV cache at 1 million-token context. V4-Flash is positioned as the cheapest frontier-adjacent inference tier in the market, undercutting GPT-5.4 Nano, Claude Haiku, and Gemini Flash on API pricing.

DeepSeek releases its models as open-weight under permissive licenses, making them freely available for download and modification, and operates the DeepSeek chat platform and API at pricing significantly below Western alternatives. The company's R1 release was a watershed moment for the AI industry, challenging the prevailing assumption that frontier AI capabilities require hundreds of millions of dollars in training compute — efficiency innovations including novel training techniques and architecture optimizations sent shockwaves through Silicon Valley and temporarily wiped hundreds of billions from NVIDIA's market cap.

Founder Liang Wenfeng has publicly committed to keeping DeepSeek on an open-source path and pursuing artificial general intelligence as the company's core goal, resisting the usual pressure to chase near-term commercialization. That posture is unusual at this valuation tier — most frontier US labs draw their largest checks from corporate cloud partners (OpenAI and Microsoft, Anthropic and Amazon) and treat AGI claims with strategic ambiguity. DeepSeek is doing the opposite, and doing it with one of the largest state-aligned bets on AGI to date outside the United States. Beijing has extended state-secret travel restrictions — originally placed on senior DeepSeek researchers — to AI talent across Alibaba and other private firms, requiring some professionals to seek official approval before traveling abroad. The pattern signals reciprocal controls that bind the lab into a state-managed talent regime, mirroring US chip export logic in reverse. On the US side, an interagency committee has approved DeepSeek — along with memory-chip maker CXMT and more than 100 other Chinese firms — for addition to the Commerce Department's Entity List on national-security grounds, though the administration has so far held off on the listing to avoid escalating tensions with Beijing; among the cited concerns is Anthropic's allegation that DeepSeek attempted to extract capabilities from its Claude models.
