*aanaphi2-v0.1* is a finetuned (SFT + DPO) chat model based on Microsoft's Phi-2 base model (2.8B parameters).
## Performance
| Models | phi-2 | aanaphi2-v0.1 |

| HellaSwag (10-shot)| 75.11 | 78.30 |
| MMLU (5-shot) | 58.11 | 57.70 |
| TruthfulQA-MC2 | 44.47 | 51.55 |
| Winogrande (5-shot)| 74.35 | 73.40 |
| GSM8K (5-shot) | 54.81 | 58.60 |
| Average | 61.33 | 63.88 |
## Basic Usage
``` Python
#Load model
import transformers, torch
compute_dtype = torch.float16
cache_path = ''
device = 'cuda'
model_id = "mobiuslabsgmbh/aanaphi2-v0.1"
model = transformers.AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=compute_dtype,
cache_dir=cache_path,
device_map=device)
tokenizer = transformers.AutoTokenizer.from_pretrained(model_id, cache_dir=cache_path)
#Set Prompt format
instruction_template = "### Human: "
response_template = "### Assistant: "
def prompt_format(prompt):
out = instruction_template + prompt + '\n' + response_template
return out
model.eval();
@torch.no_grad()
def generate(prompt, max_length=1024):
prompt_chat = prompt_format(prompt)
inputs = tokenizer(prompt_chat, return_tensors="pt", return_attention_mask=True).to('cuda')
outputs = model.generate(**inputs, max_length=max_length, eos_token_id= tokenizer.eos_token_id)
text = tokenizer.batch_decode(outputs[:,:-1])[0]
return text
#Generate
print(generate('If A+B=C and B=C, what would be the value of A?'))
```
## Installation
> As the time of writing Phi-2 is only supported has been integrated in the development version (4.37.0.dev) of transformers. Until the official version is released through pip, ensure that you update your local transformers to the development version: pip uninstall -y transformers && pip install git+https://github.com/huggingface/transformers.
