In this talk, I present my lab’s work in building models that can follow natural language instructions to perform a wide range of tasks. These models, known as "instruction-tuned" language models, have demonstrated the ability to generalize to new tasks. I first present our meta-dataset – called Super-Natural Instructions – that includes 1,600 NLP tasks and their descriptions to evaluate cross-task generalization. Later, I present our new work, Self-Instruct that improves the instruction-following capabilities of language models without relying on extensive manual annotation. It does this by using the model's own generations to create a large collection of instructional data. Finally, I present how these models can be augmented with retrieval to improve the factuality of the generated responses.
