# KafkaLM-7B-German-V0.1 |
|
|
|
**KafkaLM 7b** 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-DPO" |
|
|
|
model = AutoModelForCausalLM.from_pretrained(model_id, load_in_4bit=True, trust_remote_code=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() |
|
|
|
|
|

|

|
|
|
#print(prompt) |
|
|
|

|

|

|

|

|

|

|

|
) |
|
|
|
with torch.no_grad(): |
|
generation_output = model.generate( |
|

|
#eos_token_id=tokenizer.eos_token_id, |
|

|

|

|
#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?")) |
|
|
|
``` |
