# Model card for RWKV-4 | 14B parameters chat version (Raven) |
|
|
|
RWKV is a project led by [Bo Peng](https://github.com/BlinkDL). Learn more about the model architecture in the blogposts from Johan Wind [here](https://johanwind.github.io/2023/03/23/rwkv_overview.html) and [here](https://johanwind.github.io/2023/03/23/rwkv_details.html).

## TL;DR |
|
|
|
Below is the description from the [original repository](https://github.com/BlinkDL/RWKV-LM) |
|
> 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`](https://github.com/huggingface/transformers/tree/main/src/transformers/models/rwkv/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. |
|
|
|
```bash |
|
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: |
|
The "Raven" models needs to be prompted in a specific way, learn more about that [in the integration blogpost](https://huggingface.co/blog/rwkv). |

tokenizer = AutoTokenizer.from_pretrained("RWKV/rwkv-raven-14b") |
|
|
|
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) |
