AI Tools Drive Major Scientific Advances as Usage-Based Pricing Replaces Subscriptions
Stanford's James Zou has spent well over US$100,000 on artificial intelligence in the past year while hailing a new golden age of science. OpenAI and GitHub have raised prices or changed billing, citing surging usage and the demands of agentic AI. An economist in Vienna hit usage limits on his university-paid Claude subscription in late April.

Researchers are confronting higher costs for artificial intelligence tools as providers hike prices and tighten usage limits in response to mounting computing expenses. James Zou, who leads the AI for Science Laboratory at Stanford University in California, has spent well over US$100,000 on artificial intelligence in the past year.
He says the AI fees are in the same ballpark as the cost of supporting a postdoctoral fellow at Stanford.
Zou says we are entering into a new golden age of science with AI assistance that enables fundamental scientific advances because of their increasing capabilities of these AI scientist agents. @Nature reported that AI providers have been hiking up prices and tightening usage limits after struggling to make the economics work on subscription plans.
In January 2025, Sam Altman posted on X that OpenAI was losing money on its $200-a-month ChatGPT Pro subscriptions.
Sam Altman said people were using the chatbot more than OpenAI expected, driving up computing power and electricity costs. GitHub announced on 27 April that it would move GitHub Copilot from a subscription-based service to usage-based billing effective 1 June. GitHub cited the higher demands of agentic AI as the reason for changing its Copilot pricing policy.
Those shifts are reaching scientists who have grown reliant on the tools. Attila Gáspár, an economist at Central European University in Vienna, has been using AI to extract data from historical documents. For around 18 months, Attila Gáspár used his university-paid subscription to Claude without restrictions.
