 RWKV is a novel large language model architecture, [with the largest model in the family having 14B parameters](https://huggingface.co/BlinkDL/rwkv-4-pile-14b). In contrast to Transformer with `O(n^2)` attention, RWKV requires only state from previous step to calculate logits. This makes RWKV very CPU-friendly on large context lenghts.
 
+This project provides [a C library rwkv.h](rwkv.h) and [a convinient Python wrapper](rwkv%2Frwkv_cpp_model.py) for it.

 1. Measure performance and perplexity of different model sizes and data types

+#### 2.1. Optionally, quantize the model
+
+To convert the model into INT4 quantized format, run:
+
+```commandline
+python rwkv\quantize.py C:\rwkv.cpp-169M.bin C:\rwkv.cpp-169M-Q4_1.bin 3
+```
+
+Pass `2` for `Q4_0` format (smaller size, lower quality), `3` for `Q4_1` format (larger size, higher quality).

 ### 3. Run the model
 
 **Requirements**: Python 3.x with [PyTorch](https://pytorch.org/get-started/locally/) and [tokenizers](https://pypi.org/project/tokenizers/).
