About ChatRWKV
ChatRWKV is an open-source chatbot powered by the RWKV language model, a 100% RNN architecture that matches transformer quality and scaling while being faster and using less VRAM. Developed by BlinkDL, it offers Gradio demos, API access, and supports various inference backends including CUDA, Vulkan, and CPU. The latest version is RWKV-7, with weights available on Hugging Face. It provides local inference for Android/iOS via the RWKV app and supports fine-tuning with LoRA/QLoRA.

FAQ
What is RWKV?
RWKV is a 100% RNN (recurrent neural network) language model architecture that can match transformer quality and scaling while being faster and saving VRAM. It is the only RNN as of now that achieves this parity.
How does ChatRWKV compare to ChatGPT?
ChatRWKV is like ChatGPT but powered by the RWKV model. It is open-source, can run locally, and aims to provide similar conversational capabilities with lower resource requirements.
Is ChatRWKV free?
Yes, ChatRWKV is completely free and open-source. You can download and run it on your own hardware.
What hardware do I need to run ChatRWKV?
You can run it on CPU, NVIDIA GPUs with CUDA, AMD/Intel GPUs via Vulkan, or using cuBLAS/CLBlast. Quantized versions (int4/int8) reduce memory requirements.
