Catalunya recupera la normalitat després de la gran apagada general de dilluns. També a la xarxa de Rodalies, on ja funciona el servei a la majoria de línies, tot i que alguns trens continuen fent la guitza als viatgers i poden circular fora de l'horari habitual. Segons informa Renfe, el servei funciona amb normalitat excepte a l'R3 entre Ripoll i l'Hospitalet, on es gestiona servei alternatiu per carretera entre Puigcerdà i Ripoll, i a l'R4 Sud entre els Monjos i L'Arboç.

Enhance language models with real-time document retrieval and dynamic knowledge integration using retrieval-augmented generation and LlamaIndex. Large language models (LLMs) like ChatGPT and Llama excel at answering questions but are limited to the knowledge they were trained on. They can't access private data or learn beyond their training cut-off. So, the main is... how can we extend their knowledge? The answer lies in retrieval-augmented generation (RAG).
