# LLäMmlein 1B Chat

![image/png](/static-proxy?url=https%3A%2F%2Fcdn-uploads.huggingface.co%2Fproduction%2Fuploads%2F6070431e1a4c4d313032558b%2Fbr1m6JS0DOT_SGTHywfi3.png)

> [!WARNING]
> While the base versions of our LLäMmlein are quite good, our chat versions are research demonstrations and are not ready to be used in settings where close instruction following is necessary. Please check the paper for more details.

This is a chat adapter for the German Tinyllama 1B language model.
Find more details on our [page](https://www.informatik.uni-wuerzburg.de/datascience/projects/nlp/llammlein/) and our [preprint](arxiv.org/abs/2411.11171)!
We also merged the adapter and converted it to GGUF [here](LSX-UniWue/LLaMmlein_1B_alternative_formats).

## Run it
```py
import torch
from peft import PeftConfig, PeftModel
from transformers import AutoModelForCausalLM, AutoTokenizer

torch.manual_seed(42)

# script config
base_model_name = "LSX-UniWue/LLaMmlein_1B_prerelease"
chat_adapter_name = "LSX-UniWue/LLaMmlein_1B_chat_selected"
device = "cuda"  # or mps

# chat history
messages = [
    {
        "role": "user",
        "content": """Na wie geht's?""",
    },
]

# load model
config = PeftConfig.from_pretrained(chat_adapter_name)
base_model = model = AutoModelForCausalLM.from_pretrained(
    base_model_name,
    torch_dtype=torch.bfloat16,
    device_map=device,
)
base_model.resize_token_embeddings(32064)
model = PeftModel.from_pretrained(base_model, chat_adapter_name)
tokenizer = AutoTokenizer.from_pretrained(chat_adapter_name)

# encode message in "ChatML" format
chat = tokenizer.apply_chat_template(
    messages,
    return_tensors="pt",
    add_generation_prompt=True,
).to(device)

# generate response
print(
    tokenizer.decode(
        model.generate(
            chat,
            max_new_tokens=300,
            pad_token_id=tokenizer.pad_token_id,
            eos_token_id=tokenizer.eos_token_id,
        )[0],
        skip_special_tokens=False,
    )
)
