RWKV-5-World-7B

Efficient Open AI at Scale

What is RWKV-5-World-7B?

RWKV-5-World-7B is a 7-billion-parameter open-source language model built on the unique RWKV architecture, a hybrid of recurrent neural networks (RNNs) and transformers. It delivers the training flexibility of transformers with the inference efficiency of RNNs, making it ideal for low-latency, high-performance applications.

This model version ("World") is tuned for multilingual coverage, chat tasks, and reasoning abilities, positioning it as a powerful, lightweight alternative to traditional transformer-only LLMs.
