DeepSeek leads surge in low-cost Chinese open-weight models on US platform
Chinese open-weight AI models are seeing record usage on Vercel’s AI Gateway, a US web development platform. DeepSeek’s lightweight model is a primary driver of this surge. Open-weight models accounted for 62 percent of token volume on the platform on Saturday, a sharp increase from 28 percent on June 24. This growth comes as demand for high-cost proprietary models, such as Anthropic’s Fable 5, reportedly stalls. The shift reflects a growing preference for more affordable, accessible AI solutions in the business sector.
The surge in Chinese open-weight AI models on Vercel’s AI Gateway points to a clear market shift: cost is now a dominant factor for businesses adopting AI. DeepSeek’s lightweight model is leading this trend, pushing open models to a 62 percent share of token volume on the platform by Saturday. This is a significant reversal from June 24, when open-weight models held only 28 percent. For Asian enterprises, this suggests a strong incentive to explore and integrate more cost-effective AI solutions, potentially accelerating AI adoption among SMEs and startups that cannot afford premium proprietary models. However, the reliance on US platforms for deployment means that while Chinese models are gaining traction, their operational reach is still tied to existing infrastructure. The immediate upside for Chinese AI developers is increased visibility and adoption. The thing to watch is whether this usage translates into greater investment in open-source AI within Asia, fostering a more independent ecosystem for model development and deployment, rather than just consumption.
