Introduction

DeepSeek’s rapid ascent has upended the notion of US-only dominance in AI. By achieving top rankings in performance benchmarks—and doing so more cost-effectively than many established players—DeepSeek has made investors rethink the competitive landscape. Its models, particularly DeepSeek V2 and Coder V2, have demonstrated high performance on various tasks, signaling that a new AI contender has firmly arrived.

One key factor behind DeepSeek’s success is its cost-efficient approach. Rather than relying on the latest, most expensive hardware, DeepSeek has shown that world-class AI models can be trained with more modest chips and thoughtfully optimized training methods. This cost advantage not only allows DeepSeek to price its AI services competitively but also increases accessibility for smaller businesses and developers who might otherwise be priced out of advanced AI tools.
