Wiedervereinigung-7b-dpo-laser

Some of the best german models with 7b parameters as lasered dpo-trained dare_ties merge.

Since the original models based on mistral - three of them on the brilliant german LeoLM/leo-mistral-hessianai-7b - they are reunited in this merged model. Hence the name. To improve result quality they are dpo-trained with a german translation of oaast-dpo using our german fork of LLaMA-Factory. After that this model got a laserRMT treatment.

Wiedervereinigung-7b itself is a LazyMergekit merge of:

• DiscoResearch/DiscoLM_German_7b_v1
• DRXD1000/Phoenix
• VAGOsolutions/SauerkrautLM-7b-v1-mistral
• malteos/hermeo-7b

All the actual heavylifting has been done by the creators of these models.

Using laser and dpo results in pretty good results.

💻 Usage

!pip install -qU transformers accelerate

from transformers import AutoTokenizer
import transformers
import torch

model = "mayflowergmbh/Wiedervereinigung-7b-dpo-laser"
messages = [{"role": "user", "content": "Was ist ein large language model?"}]

tokenizer = AutoTokenizer.from_pretrained(model)
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
pipeline = transformers.pipeline(
    "text-generation",
    model=model,
