20 minutos por dia.
Foi o que usei para concluir 5 cursos, passar nas avaliações e colocar um projeto no ar -- dentro de uma rotina cheia, sem fins de semana inteiros de estudo.

Vector databases vs traditional databases 👇
📖 Traditional DB:
searches for words
🧠 Vector DB:
searches for meaning
Search for "pet" and you might get:
🐶 dog
🐕 puppy
🐱 cat
That's why vector databases power RAG and semantic search.
