Chinese open-weight AI models surpass proprietary usage on US development platform

Chinese open-weight models, led by DeepSeek, reached a record 62% share of token volume on Vercel's AI Gateway, overtaking proprietary models. The shift reflects a growing preference for cost-effective alternatives over high-cost proprietary options like Anthropic's Fable 5. It remains uncertain if this trend indicates a broader structural shift in enterprise AI adoption or a temporary reaction to current pricing models.
