# KafkaLM-7B-German-V0.1

**KafkaLM 70b** is a Mistral 7b model - further pre-trained on a large german dataset from Björn Plüster and LAION. [leo-mistral-hessianai-7b](https://huggingface.co/LeoLM/leo-mistral-hessianai-7b) - which was finetuned on an ensemble of popular high-quality open-source instruction sets (translated from English to German). 

KafkaLM 7b is a [Seedbox](https://huggingface.co/seedboxai) project trained by [Dennis Dickmann](https://huggingface.co/doubledsbv).

**Why Kafka?** 
The models are proficient, yet creative, have some tendencies to linguistically push boundaries 😊


## Model Details

The purpose of releasing the **KafkaLM series** is to contribute to the German AI community with a set of fine-tuned LLMs that are easy to use in everyday applications across a variety of tasks.

The main goal was to provide LLMs proficient in German, especially to be used in German-speaking business contexts where English alone is not sufficient.

### DPO

The model has been aligned with a german and modified version of the ultra feedback dataset from huggingface. 

### Dataset

I used a 8k filtered version of the following [seedboxai/multitask_german_examples_32k](https://huggingface.co/datasets/seedboxai/multitask_german_examples_32k)

### Prompt Format


This model follows the subsequent prompt format:

```
<|system|>
Du bist ein freundlicher und hilfsbereiter KI-Assistent. Du beantwortest Fragen faktenorientiert und präzise, ohne dabei relevante Fakten auszulassen.</s>
<|user|>
Welche Möglichkeiten der energetischen Sanierung habe ich neben Solar und Energiespeicher?</s>
<|assistant|>
```

### Inference

Getting started with the model is straightforward

```python
import transformers

model_id = "seedboxai/KafkaLM-7B-German-V0.1"

model = AutoModelForCausalLM.from_pretrained(model_id, load_in_4bit=True)

tokenizer = AutoTokenizer.from_pretrained(model_id)

tokenizer.padding_side = "left"  
tokenizer.pad_token = tokenizer.unk_token 
tokenizer.add_eos_token = False

def generate_prompt(input):
    prompt = ''
    sys_prompt = "Du bist ein freundlicher und hilfsbereiter KI-Assistent. Du beantwortest Fragen faktenorientiert und präzise, ohne dabei relevante Fakten auszulassen."
    
    prompt += f"<|system|>\n{sys_prompt.strip()}</s>\n"
    prompt += f"<|user|>\n{input.strip()}</s>\n"
    prompt += f"<|assistant|>\n"

    return prompt.strip()


def evaluate(
    input,
    temperature=0.5,
    top_p=0.95,
    top_k=50,
    num_beams=3,
    max_new_tokens=512,
    #max_length=4096,
    **kwargs,
):
    prompt = generate_prompt(input)

    #print(prompt)
    
    inputs = tokenizer(prompt, return_tensors="pt")
    input_ids = inputs["input_ids"].to(device)
    attention_mask=inputs["attention_mask"].to(device)
    generation_config = GenerationConfig(
        temperature=temperature,
        top_p=top_p,
        top_k=top_k,
        num_beams=num_beams,
        no_repeat_ngram_size=3,
        do_sample=True,
        **kwargs,
    )

    with torch.no_grad():
        generation_output = model.generate(
            early_stopping=False,
            #eos_token_id=tokenizer.eos_token_id,
            #pad_token_id=tokenizer.pad_token_id,
            input_ids=input_ids,
            attention_mask=attention_mask,
            generation_config=generation_config,
            return_dict_in_generate=True,
            output_scores=True,
            max_new_tokens=max_new_tokens,
            #max_length= max_length
        )
    s = generation_output.sequences[0]
    output = tokenizer.decode(s)
    return output #.split("<|assistant|>")[1].strip()


print(evaluate("Wer ist eigentlich dieser Kafka?"))

```
