The Weekend DeepSeek-R1 Shook the AI Market
Released January 20, 2025, DeepSeek-R1 is arguably the single most consequential open-weight release covered in this series. It was among the first openly available models to demonstrate strong step-by-step reasoning performance rivaling closed frontier "reasoning" models, and its release triggered an immediate, widely reported reaction across financial markets and the broader AI industry within days.
Why it mattered
R1 forced a rapid, public reassessment of assumptions about how much compute and capital were actually required to reach frontier-level reasoning performance -- and did so under the MIT license, placing a genuinely frontier-class reasoning model in the hands of anyone who wanted to download, inspect, or build on it. Few open-weight releases before or since have had comparable real-world market and industry impact.
