RWKV

RWKV is an RNN architecture that provides transformer-level language model performance while allowing parallelizable training like a GPT model.

RWKV is a neural network architecture designed for large language models and multimodal applications. It operates as a 100% recurrent neural network that achieves performance parity with transformers. The architecture functions in linear time and constant space, which eliminates the need for a traditional KV-cache during inference. It combines the benefits of RNNs with the ability to perform parallel training, offering a unique approach to model scalability. This system serves developers and researchers building high-performance AI models who require efficient memory usage and inference speeds. It is a Linux Foundation AI project available for community development.
