Open-weight models now beat proprietary alternatives on hallucination, coding, and general benchmarks. The AI quality hierarchy has flipped.
GLM-5.2, an MIT-licensed Chinese model, hallucinates 3x less than GPT-5.5. ChatGPT market share dropped below 50% for the first time. DeepSeek raised $7 billion. The quality hierarchy that justified proprietary AI pricing has structurally inverted, and the consequences for enterprise procurement are immediate.
