Model reference · open weights
Phi-Hermes is an open-weight language model from teknium. AxForge deploys and operates it for you on dedicated EU-owned hardware — with the licence handled where one is required.
Available as managed deployment — configured and operated for you on dedicated EU hardware, quoted per deployment.

About
Phi-1.5 fine tuned with Hermes Dataset
This model was trained on the OpenHermes Dataset, made by me, which is over 240,000 mostly GPT-4 generated synthetic datapoints
Let me know!
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:

Using it via the API
Once AxForge deploys phi-hermes for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (phi-hermes 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":"phi-hermes","messages":[{"role":"user","content":"Hello"}]}'
