Generative Representational Instruction Tuning

Niklas Muennighoff, Hongjin Su, Liang Wang +5

All text-based language problems can be reduced to either generation or embedding. Current models only perform well at one or the other. We introduce generative representational in…

LongEmbed: Extending Embedding Models for Long Context Retrieval

Dawei Zhu, Liang Wang, Nan Yang +4

Embedding models play a pivot role in modern NLP applications such as IR and RAG. While the context limit of LLMs has been pushed beyond 1 million tokens, embedding models are stil…
