SWAN-GPT: An Efficient and Scalable Approach for Long-Context Language Modeling

Krishna C. Puvvada, Faisal Ladhak, Santiago Akle Serrano +8

We present a decoder-only Transformer architecture that robustly generalizes to sequence lengths substantially longer than those seen during training. Our model, SWAN-GPT, interlea…
