# Model Card for Puffin-Phi V2

This is my first fine-tune of Puffin that seems to be working fairly reliably!

## Model Details

### Model Sources

This model was trained on the Puffin Dataset, made by LDJ, using a slightly modified version of the dataset that removed >2000 token entries, so there would be no early cutoffs during training phi, since it's context is 2k.

## Uses

Let me know!

## How to Get Started with the Model

Phi does not support device_map "auto", and does not seem to want to inference in fp16, so use bf16.

Here is working code to inference, though it can be improved:

```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

sysprompt = "The assistant gives helpful, detailed, and polite answers to the user's questions.\n"

model = AutoModelForCausalLM.from_pretrained("teknium/Puffin-Phi-v2", trust_remote_code=True, torch_dtype=torch.bfloat16).to("cuda")
tokenizer = AutoTokenizer.from_pretrained("teknium/Puffin-Phi-v2", trust_remote_code=True, torch_dtype=torch.bfloat16)
inputs = tokenizer(f"{sysprompt}USER: Write a negative review for the website Twitter.\nASSISTANT:", return_tensors="pt", return_attention_mask=False)
outputs = model.generate(**inputs, max_length=128, do_sample=True, temperature=0.2, top_p=0.9, use_cache=True, repetition_penalty=1.2, eos_token_id=tokenizer.eos_token_id)
text = tokenizer.batch_decode(outputs)[0]
print(text)
```

The prompt format is ShareGPT/Vicuna, so it uses the sysprompt (defualt in sysprompt variable)
then is prompted like so:

```
USER: <prompt>
ASSISTANT:
```
