Citi sees AI model progress outpacing data center infrastructure

Investing.com - AI capabilities are advancing but generating returns requires infrastructure and enterprises to keep pace, Citi said in a research note released Monday.

A central theme at the infra/STRUCTURE Summit was that maintaining data center project timelines increasingly depends on working with local communities rather than simply building around them, making responsible development a key enabler of long-term capacity expansion. At AlphaSummit, AlphaSense said AI performs 98% of platform research, although Lanai CEO Lexi Reese estimated only about 2% of companies can directly tie AI usage to revenue or profit.

The intelligence ceiling rose 9% month-over-month and total model releases over a trailing 90-day window increased 38% month-over-month for proprietary models versus 7% month-over-month for open models, Citi said. An unreleased model reportedly solved 90 of the top 500 open problems in math on October 7, and frontier models' research efficiency has doubled every 3 months according to TasteVal. Reflection AI reported on October 5 that its latest open-weight model, Beam, achieves GLM-5.2-level results with 3-4x less compute, and Mistral trained Large 4 on 3,800 Blackwells on October 6.

Local support will continue to shape where capital for data center buildouts is deployed over the next month, with Oklo at infra/STRUCTURE Summit citing restrictions across 400-plus communities in 43 states and Amazon (NASDAQ: AMZN) committing $1 billion over 5 years on October 6 to data center communities. Enterprises are buying 5-40MW blocks in sub-year cycles, according to First Citizens, despite turnkey shell costs rising from $8-10 million per MW in 2018-20 to $12-14 million today, with power shells as high as roughly $5 million depending on land costs.

GPU demand continues to strengthen, with H100, B200, and B300 rental prices rising 7.6%, 2.7%, and 17.5% week-over-week. Vercel's closed-model share doubled from 23% to 46% over the past 2 weeks, narrowing open models' lead to 54%.
