Story summary

On Saturday, 62% of models used on Vercel's US web development platform were open-weight models from China, a record high and a reversal from June when only 28% were open-weight. The surge was driven by DeepSeek's latest lightweight model, which has become popular due to its low cost. Meanwhile, business demand for Anthropic's cutting-edge Fable 5 has stalled because it is too expensive. On Vercel's AI Gateway, 54% of token volume was accounted for by open-weight models on Tuesday, surpassing the 46% consumed by proprietary models. This shift in usage marks a significant change from June when closed systems dominated with 72% of token volume.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
