Exponential View Data Weekly: Open-weight token share doubles in a year, AI agent token usage reaches 14 times that of humans
The latest inference token data from Exponential View shows that the open-weight token share has doubled over the past twelve months and is approaching a 1:1 ratio of closed-source to open-source, but over the same period the number of closed-weight tokens grew sevenfold. The volume of tokens used by AI agents in February of this year has already surpassed that of humans, and currently stands at 14 times that of humans, while human token usage grew only 2.8 times. The employment rate of young workers aged 22–25 in AI-exposed occupations is now 19% below the trend line, up from 15% last year.
