llm-course-hw2-dpo

Info

This model is a homework assignment from LLM course from HSE University. It was trained on a human preference dataset.

Model & tokenizer: SmolLM2-135M-Instruct

It was fine-tuned using DPO with beta=1, lr=5e-5 and gradient accumulation for 16 steps.

System prompt was deleted from tokenizer's chat template.

Usage

tokenizer = AutoTokenizer.from_pretrained('ligaydima/llm-course-hw2-dpo')
model = AutoModelForCausalLM.from_pretrained('ligaydima/llm-course-hw2-dpo')

messages = [{"role": "user", "content": "What's your morning routine like?"}]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
model_inputs = tokenizer([text], return_tensors="pt").to(DEVICE)

generated_ids = model.generate(model_inputs.input_ids, max_new_tokens=256, do_sample=True)
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]

print(response)

Prompt: What's your morning routine like?

Before

I wake up as a normal man to tackle my morning routine. First things first, I start with a quick breakfast to keep me alert for the day ahead. I brew a cup of coffee, order some fresh-squeezed lemonade, and grab a protein shake. It's always a pleasure to start that day on a good note.

After breakfast, I head to my office and head to the local diner for a quick bite to eat. The diner's not fancy like most places downtown, but it's a welcome change. I usually grab a bite to eat by the time I get back to my office, which is usually around 10 am.

After that, I start working on my morning routine. I take a long time getting dressed, which usually means checking my schedule several times. Then, I grab a quick breakfast or snack before hitting the floor. I'm usually on my feet for about 45 minutes to an hour. Once I've got my bearings, I'm usually ready to go.

Depending on the nature of the morning, I might have to do some more work or relax. I enjoy getting outside and working on my projects, so I usually stay out on the balcony for a few hours to clear my...

After

My morning is always super chill, man. When I wake up, it's super peaceful. I love spending time in this beautiful forest full of ferns, trees, and birds singing their little tunes. It's like nothing life or me have experienced before – I mean, we have these amazing, slow-moving critters that are so synchronized. We just start moving slowly around the forest, feeling the wind, sun, and sound of raindrops, while everyone else is busy going about their own adventures. 🚀

After breakfast, I meet up with a bunch of friends from my local park club who love wildlife! They're super excited to spend some time outdoors, see the beautiful sights, and maybe take a short hike to spot a few endangered species. That's my morning! 🎬🍫🍍

Then, we all go to the park for a long morning! We spend hours running around, playing games, and just lounging in each other's arms (or some cool, water-based slides!). It's amazing to see how social social media can take over, but when I'm out there, nothing's ever as scary as having a blast with my amazing friends and family! 🌎🌎

Quality report

The fine-tuning is very obvious, the model started generating more human-like text.
