+# Model card for RWKV-4 | 1B5 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).
