+# Genji-python 6B
+
+## Model Description
+
+Genji is a transformer model finetuned on EleutherAI's GPT-J 6B model. This particular model is trained on python only code approaching 4GB in size.
+
+| Hyperparameter    | Value  | 
+|-------------------|--------|
+| n_parameters      | 6,053,381,344 |
+| n_layers          | 28*    |
+| d_model           | 4,096  |
+| d_ff              | 16,384 |
+| n_heads           | 16     |
+| d_head            | 256    |
+| n_ctx             | 2,048  |
+| n_vocab           | 50,400 (same tokenizer as GPT-2/3)  |
+| position encoding | [Rotary position encodings (RoPE)](https://arxiv.org/abs/2104.09864) |
+| RoPE dimensions   | [64](https://github.com/kingoflolz/mesh-transformer-jax/blob/f2aa66e0925de6593dcbb70e72399b97b4130482/mesh_transformer/layers.py#L223) |
+
+`*` each layer consists of one feedforward block and one self attention block
+
+The model consists of 28 layers with a model dimension of 4096, and a feedforward dimension of 16384. The model
+dimension is split into 16 heads, each with a dimension of 256. Rotary position encodings (RoPE) was applied to 64
+dimensions of each head. The model is trained with a tokenization vocabulary of 50257, using the same set of BPEs as
+GPT-2/GPT-3.
+
+## Training data
+
+GPT-J 6B was pretrained on the [Pile](pile.eleuther.ai), a large scale curated dataset created by EleutherAI for the purpose of training this model. After the pre-training, it's finetuned on the python code that was taken from the Pile.
+
+## Training procedure
+
+Genji-python-6B is trained for 20k steps on around 655 million tokens. For LR we used a warmup steps of 2000 and annual decrease of learning rate from 5e-06 to 1e-06.
+
+## Intended Use
+
+This model is trained for assistence on writing python code and having fun trying weird stuff with it. 
+
+### How to use
+
+This model is only usable with our fork because GPT-J is not merged to the main transformers repo yet. When it's merged, we will make this model easily loadable.
+For now, you need to use this fork:
+[Fork](https://github.com/finetuneanon/transformers)
+
+to install with pip:
+```bash
+pip install git+https://github.com/finetuneanon/transformers@gpt-neo-localattention3-rp-b
+```
+
+This model takes more than 16 gigs of RAM to load. If you want more efficient and faster loading, please check our split model.
+We recommend the usage of the model as FP16. That way, it fits in 16GB VRAM cards.
+
+How to use:
+```python
+from transformers import (
+    AutoTokenizer,
+    AutoModelForCausalLM,
+    GPTNeoForCausalLM,
+)
+
+model = AutoModelForCausalLM.from_pretrained("NovelAI/genji-python-6B", use_auth_token=True).half().eval().cuda()
+tokenizer = AutoTokenizer.from_pretrained("EleutherAI/gpt-neo-2.7B")
+
+text = '''def print_customer_name'''
+
+tokens = tokenizer(text, return_tensors="pt").input_ids
+generated_tokens = model.generate(tokens.long().cuda(), use_cache=True, do_sample=True, top_k=50, temperature=0.3, top_p=0.9, repetition_penalty=1.125, min_length=1, max_length=len(tokens[0]) + 400, pad_token_id=tokenizer.eos_token_id)
+last_tokens = generated_tokens[0][len(tokens[0]):]
+generated_text = tokenizer.decode(last_tokens)
+print("Generation:\n" + generated_text)
+```
+When ran, this code generates:
+```python
+Prompt:
+def print_customer_name
+Generation:
+(self, customer):
+        """Print the name of a customer."""
+        if not self.is_valid():
+            return
+
+        print("Customer: {}".format(customer))
+```
