filefunction / class

Why would anyone build with this?

REASON 1

Classify text sentiment or extract answers from documents using a pretrained model in a few lines of code

REASON 2

Summarize long articles or translate text between languages without training a model from scratch

REASON 3

Fine-tune a pretrained model on your own data, like detecting complaints in customer support emails

REASON 4

Build a chatbot or content moderation tool using off-the-shelf state-of-the-art language models
