## Basic Usage

<details>

<summary>Setup</summary>

```python
!pip install -qU transformers accelerate

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

model = "dfurman/HermesBagel-34B-v0.1"

tokenizer = AutoTokenizer.from_pretrained(model)

model = AutoModelForCausalLM.from_pretrained(
    model,
    torch_dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True,
)
```

</details>


```python
messages = [
    {"role": "user", "content": "What is a large language model?"},
]

print("\n\n*** Prompt:")
input_ids = tokenizer.apply_chat_template(
    messages,
    tokenize=True,
    return_tensors="pt",
)
print(tokenizer.decode(input_ids[0]))

print("\n\n*** Generate:")
with torch.autocast("cuda", dtype=torch.bfloat16):
    output = model.generate(
        input_ids=input_ids.to("cuda"),
        max_new_tokens=256,
        return_dict_in_generate=True,
        do_sample=True, 
        temperature=0.7, 
        top_k=50, 
        top_p=0.95
    )

response = tokenizer.decode(
    output["sequences"][0][len(input_ids[0]):], 
    skip_special_tokens=True
)
print(response)
