Qwen1.5-7B-Dutch-Chat-Dpo

Model description

This DPO aligned model is an adapter model based on robinsmits/Qwen1.5-7B-Dutch-Chat-Sft.

DPO Finetuning was performed on the Dutch BramVanroy/ultra_feedback_dutch_cleaned dataset.

See Qwen/Qwen1.5-7B-Chat for all information about the base model.

Model usage

A basic example of how to use the finetuned model.

import torch
from peft import AutoPeftModelForCausalLM
from transformers import AutoTokenizer

device = 'cuda'
model_name = 'robinsmits/Qwen1.5-7B-Dutch-Chat-Dpo'

model = AutoPeftModelForCausalLM.from_pretrained(model_name, 
                                                 device_map = "auto", 
                                                 load_in_4bit = True,
                                                 torch_dtype = torch.bfloat16)

tokenizer = AutoTokenizer.from_pretrained(model_name)

messages = [{"role": "user", "content": "Hoi hoe gaat het ermee? Wat kun je me vertellen over appels?"}]

encoded_ids = tokenizer.apply_chat_template(messages, 
                                            add_generation_prompt = True,
                                            return_tensors = "pt")

generated_ids = model.generate(input_ids = encoded_ids.to(device), 
                               max_new_tokens = 256,
                               do_sample = True)
decoded = tokenizer.batch_decode(generated_ids)
print(decoded[0])

Hoi hoe gaat het ermee? Wat kun je me vertellen over appels?<|im_end|>
<|im_start|>assistant
Hallo! Appels zijn zoet, knapperig en hebben een mooie smaak. Ze zijn groen met roze tinten en er zijn verschillende soorten zoals de Granny Smith, Red Delicious en Gala. Er wordt gezegd dat appels goed zijn voor je gezondheid omdat ze veel vezels en vitamines bevatten. Ook kunnen ze lekker worden gegeten zonder te bakken of te koken. Er zijn ook veel verschillende dingen die je met appels kunt doen zoals het maken van appeltaart of het drinken van appelcider.<|im_end|>

Intended uses & limitations

As with all LLM's this model can also experience bias and hallucinations. Regardless of how you use this model always perform the necessary testing and validation.

The used dataset does not allow commercial usage.
