DeepSeek Accused of Silently Swapping Models Behind Its API, Sparking Debate

Chinese developer tison1096 complained about DeepSeek: he ordered one model via API but got served a different one — 'you ordered lamb, they said beef tastes better and is cheaper, and now lamb orders get beef.' He analogized that AWS would never ship you a t3a instance when you selected c7a. teortaxesTex pushed back: DeepSeek isn't AWS, you have no long-term enterprise contract with them, and they don't care about your use case — implying silent model swaps are somewhat expected in no-contract cheap API services. The exchange highlights a gray zone in model-as-a-service: silent server-side model substitution with no way for users to verify or hold anyone accountable.
