One of the focus areas at Together Research is new architectures for long context, improved training, and inference performance over the Transformer architecture. Spinning out of a research program from our team and academic collaborators, with roots in signal processing-inspired sequence models, we are excited to introduce the StripedHyena models. This release includes StripedHyena-Hessian-7B (SH 7B), a base model, and StripedHyena-Nous-7B (SH-N 7B), a chat model. StripedHyena builds on the many lessons learned in the past year on designing efficient sequence modeling architectures: H3, Hyena, HyenaDNA, and Monarch Mixer.
