Project comparison

RWKV LM vs Lightrag

Compare adoption, momentum, maintenance health, and project basics before choosing which tool to evaluate deeper.

RWKV LM

RWKV (pronounced RwaKuv) is an RNN with great LLM performance, which can also be directly trained like a GPT transformer (parallelizable). We are at RWKV-7 "Goose". So it's combining the best of RNN and transformer - great performance, linear time, constant space (no kv-cache), fast training, infinite ctx_len, and free sentence embedding.

Best matched with other inference tools.
