)Chinese AI models are cheaper due to massive GPU cluster scale, aggressive competition among 5+ labs, volume-based business models, and efficient MoE (Mixture of Experts) architecture. DeepSeek-V4-Pro costs $0.55/1M vs GPT-5's $15/1M.
For most production use cases, yes. DeepSeek-V4-Pro matches or exceeds GPT-4 on MATH, HumanEval, and MMLU benchmarks. The quality gap is 1-2 percentage points while the price gap is 27x.
