AI Infrastructure Market: Open-weight AI models gain production traction
The article discusses the shift in the AI industry from closed to open-weight models, citing that in August 2026, open models processed 56% of tokens on Vercel's AI Gateway, up from 7% in December 2025, and about 60% of US-originating token consumption on OpenRouter. While closed models still lead at the frontier, open weights are becoming part of production infrastructure. The piece introduces the concept of 'open escape velocity', where open AI develops independent sources of demand and infrastructure, reducing dependence on any single model company. However, the content is largely paywalled, and the full analysis and data are not accessible.
Indicates a significant shift in AI model adoption with production infrastructure, relevant to AI-driven advertising and marketing technologies.
