AI adoption among businesses has reached 78%, and costs have dropped 280 times. See more highlights from Stanford’s 2025 AI Index report.

  • Business AI adoption has jumped to 78%, up from 55% a year ago.
  • The cost of using advanced AI has dropped by 280 times in under two years.
  • 71% of businesses using AI in marketing report revenue gains.

Stanford University’s latest AI Index Report reveals a significant increase in AI adoption among businesses.

Now 78% of organizations use AI, up from 55% a year ago. At the same time, the cost of using AI has dropped, becoming 280 times cheaper in less than two years.

More Businesses Than Ever Are Using AI

The latest report, now in its eighth year, shows a turning point for AI in business.

The number of organizations using generative AI in at least one business area more than doubled, from 33% in 2023 to 71% in 2024.

“Business is all in on AI, fueling record investment and usage,” the report states.

In 2024, U.S. companies invested $109.1 billion in AI, nearly 12 times more than China’s $9.3 billion and 24 times more than the U.K.’s $4.5 billion.

AI Costs Are Dropping

One reason more companies are using AI is that it’s becoming increasingly affordable. The report indicates that the cost of running AI queries has decreased significantly.

The report highlights:

“The cost of querying an AI model that performs like GPT-3.5 dropped from $20.00 per million tokens in November 2022 to just $0.07 per million tokens by October 2024.”

That’s 280 times cheaper in about 18 months.

Prices have dropped between 9 and 900 times per year, depending on the use case for AI. This makes powerful AI tools much more affordable for companies of all sizes.
