RNN With Transformer-level LLM Performance. (github) According to the author: "It combines the best of RNN and transformers - great performance, fast inference, saves VRAM, fast training, "infinite" ctx_len, and free sentence embedding"

Thanks to RFT Capital for donating compute capability for our experiments. Additional thanks to the author of the rwkvstic library.
