About

What Puffin-Phi is

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:

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:
ASSISTANT:

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys puffin-phi for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (puffin-phi below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/chat/completions \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"puffin-phi","messages":[{"role":"user","content":"Hello"}]}'

Create an account — your API key is available in the console. 5M tokens/month currently included with every new account at launch.
