What happened to Luis, Sara and Peter from Deep Spanish?

They live on in Berges AI. Deep Spanish was our first AI experiment, launched in October 2022: three Spanish practice chatbots built on an early language model. Luis was the sarcastic one, Sara the super-friendly one, and Peter the grammar nerd. Today they are the chatbot layer of Berges AI. They run on current open-weights reasoning models, answer in any language and on any topic, and each sets a different tone: Luis is concise, Sara is friendly, Peter is technical.
