+# Large language model
+
+_Language models_ are computational model that can predict sequences in natural language.<br/>
+Useful for speech recognition, machine translation, natural language generation, optical character recognition, route
+optimization, handwriting recognition, grammar induction, information retrieval, and other tasks.
+
+_Large_ language models are predominantly based on transformers trained on large datasets, frequently including texts
+scraped from the Internet.<br/>
+They have superseded recurrent neural network-based models.
