El Reglamento de IA de la UE entró en vigor el 1 de agosto de 2024 y se aplica por fases. Las prohibiciones y el deber de alfabetización en IA rigen desde febrero de 2025; las obligaciones para modelos de IA de propósito general desde agosto de 2025; y el grueso del régimen de alto riesgo desde agosto de 2026, con los sistemas integrados en productos regulados en 2027.
Demos run a short happy path once with a human watching. Production runs thousands of variations unattended, where per-step error rates compound and an unbounded permission scope turns a wrong decision into an incident. The deployments that work narrow the scope, verify each step cheaply, and gate every irreversible action.
Price per token has fallen sharply through better hardware, smaller distilled models and serving optimisations. Consumption has grown faster: longer contexts, reasoning models that generate far more tokens per answer, and agents that turn one user action into dozens of model calls. Falling unit prices with rising unit counts produce larger bills.
Answer engines synthesise a response from several sources and show it above or instead of the traditional link list, so a query that once produced a visit can now be resolved without one. Publishers see impressions and citations rise while click-through falls, which breaks the advertising model that assumed every answer required a page view.
On common benchmarks the best open-weight models now sit close to frontier commercial models, and for many routine tasks the difference is not noticeable. The remaining gaps show up in long-horizon reliability, tool use, very long contexts and safety tuning — and in the operational work of running them yourself.
