## Summary

According to a Banque de France survey, two thirds of French companies with at least 20 employees use a generative AI tool and 35% use a predictive AI tool. The study concludes that the impact of these tools on productivity remains very modest for now, with only a minority of companies seeing a measurable effect. The companies surveyed nevertheless remain optimistic about the productivity gains expected in future.
