The key difference
EU AI Act takes effect first, so it is usually the more urgent of the two. California AI Transparency Act tracks 7 compliance requirements and EU AI Act tracks 10. They are not interchangeable — meeting one does not discharge the other. The practical question is not which law is “stricter,” but which of them — or both — actually applies to your business.

Which has the higher maximum penalty — California AI Transparency Act or EU AI Act?
California AI Transparency Act: $5,000 per violation (Bus. & Prof. Code § 22757.4(a)), recoverable in a civil action brought by the California Attorney General, a city attorney, OR a county counsel; a prevailing plaintiff also recovers reasonable attorney's fees and costs. The per-day accrual clause (§ 22757.4(b)) makes each day in violation a discrete violation for covered providers, large online platforms, and capture device manufacturers — GenAI hosting platforms are not named in that clause. Third-party licensees who violate § 22757.3(c) face injunctive relief and fees/costs only, not the $5,000 penalty (§ 22757.4(c)). No private right of action. EU AI Act: €35,000,000 or 7% of global annual turnover (whichever higher) for prohibited AI; €15M or 3% for high-risk violations; €7.5M or 1% for incorrect information to authorities Penalty structures differ by regulator and violation type — read each law's full page for the cure periods and per-violation detail.
