Model Card for Puffin-Phi V2

Phi-1.5 fine tuned with Hermes Dataset

Model Details

Model Sources

This model was trained on the OpenHermes Dataset, made by me, which is over 240,000 mostly GPT-4 generated synthetic datapoints

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:

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

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"### Instruction:\nWrite a negative review for the website, Twitter.\n### Response:\n", 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 Alpaca, then is prompted like so:

### Instruction:
<prompt>
### Response:
