Open-weight AI models overtake proprietary rivals in developer usage, Citi says
Open-weight AI models accounted for 53% of token volume on Vercel's AI Gateway on 25 August, up from 29% in late June, according to Citi. The performance gap between open-weight and proprietary models narrowed from 9 to 3 points. Citi noted regulatory constraints on public frontier models and highlighted DeepSeek's $71 million revenue. Nvidia's reported acquisitions of Hugging Face and Poolside could bolster the open-weight ecosystem.
