DeepSeek leads surge in low-cost Chinese open-weight models on US platform
The usage of open-weight AI models from China hit a record high on a popular US web development platform, driven largely by DeepSeek’s latest lightweight model.

Open-weight AI models from China have reached a record high on a US web development platform, driven by DeepSeek’s latest lightweight model, surpassing proprietary models in token volume.
Imagine you have a super smart robot that can do lots of things for you, like write code or reason about things. This robot needs to use lots of 'tokens' to do its job, and now there are cheaper and more open models that can do the same job, but at a lower cost. This is a big deal because it means we can make more robots like this and use them for lots of things.
Analysis
DeepSeek Dominance on Vercel AI Gateway
The recent surge in open-weight AI models from China on Vercel's AI Gateway is a significant development in the AI landscape. According to data on Vercel's website, open-weight models accounted for 54% of token volume on Tuesday, surpassing the 46% consumed by proprietary models. This was in stark contrast to the breakdown on June 24, when open-weight models accounted for only 28% of Vercel AI Gateway's token volume, compared with 72% for closed ones.
Business Demand for Anthropic's Fable 5 Stalls
The business demand for Anthropic's cutting-edge Fable 5 has stalled due to high costs. This has led to a shift in preference towards cheaper and open models like DeepSeek's latest lightweight model. The fact that open models reached a record share of 62% on Vercel's AI Gateway on Saturday, dwarfing closed systems' 38%, is a testament to this shift.
Autonomous Agents and Production Workloads
The figures indicate that developers are increasingly choosing cheaper and open models for production workloads, particularly for autonomous agents that can consume large numbers of tokens for reasoning, writing code, and calling software tools. This is a significant development in the AI landscape, as it shows a shift towards more cost-effective and open models.
Key points
- Open-weight AI models from China have reached a record high on a US web development platform.
- DeepSeek's latest lightweight model is driving the surge in open-weight models.
- Business demand for Anthropic's cutting-edge Fable 5 has stalled due to high costs.
- Developers are increasingly choosing cheaper and open models for production workloads.
If this development continues, we can expect to see more open and cost-effective models being used in production workloads, leading to increased adoption and innovation in the AI space.
However, the shift towards open models may also lead to concerns about data security and intellectual property, as more developers may be using and sharing models without proper safeguards.
