## Summary

A BCG study, previewed for La Tribune by Sylvain Duranton, global head of BCG X, indicates that companies now spend 3.3% of their revenue on deploying generative AI, double the previous year. According to the study, companies do not yet precisely measure the overall return on investment of this spending, but half of them report cost reductions of 2 to 3%.
