TL;DR
Below is the description from the original repository
RWKV is an RNN with transformer-level LLM performance. It can be directly trained like a GPT (parallelizable). It's combining the best of RNN and transformer - great performance, fast inference, saves VRAM, fast training, "infinite" ctx_len, and free sentence embedding.
Model Details
The details of the architecture can be found on the blogpost mentioned above and the Hugging Face blogpost of the integration.
Usage
Convert the raw weights to the HF format
You can use the convert_rwkv_checkpoint_to_hf.py script by specifying the repo_id of the original weights, the filename and the output directory. You can also optionally directly push the converted model on the Hub by passing --push_to_hub flag and --model_name argument to specify where to push the converted weights.
python convert_rwkv_checkpoint_to_hf.py --repo_id RAW_HUB_REPO --checkpoint_file RAW_FILE --output_dir OUTPUT_DIR --push_to_hub --model_name dummy_user/converted-rwkv
Generate text
You can use the AutoModelForCausalLM and AutoTokenizer classes to generate texts from the model. Expand the sections below to understand how to run the model in different scenarios:

from transformers import AutoModelForCausalLM, AutoTokenizer
model = AutoModelForCausalLM.from_pretrained("RWKV/rwkv-4-1b5-pile")
tokenizer = AutoTokenizer.from_pretrained("RWKV/rwkv-4-1b5-pile")
prompt = "\nIn a shocking finding, scientist discovered a herd of dragons living in a remote, previously unexplored valley, in Tibet. Even more surprising to the researchers was the fact that the dragons spoke perfect Chinese."
inputs = tokenizer(prompt, return_tensors="pt")
output = model.generate(inputs["input_ids"], max_new_tokens=40)
print(tokenizer.decode(output[0].tolist(), skip_special_tokens=True))
