+# Qwen-2.5-3B Smoltalk SFT
+
+This is a fine-tuned version of the 3-billion parameter **Qwen/Qwen2.5-3B** base model. It has been instruction fine-tuned via Low-Rank Adaptation (LoRA) and fully merged.
+
+## Model Details
+
+- **Base Model:** Qwen/Qwen2.5-3B
+- **Fine-tuning Dataset:** HuggingFaceTB/smoltalk (everyday-conversations subset)
+- **Methodology:** Supervised Fine-Tuning (SFT) using TRL
+- **Hardware Used:** 1 x NVIDIA L4 GPU (24GB VRAM)
+
+## How to Get Started
+
+You can load and use this model directly with the Hugging Face `pipeline` API.
+
+```python
+import torch
+from transformers import pipeline, AutoTokenizer, AutoModelForCausalLM
+
+MODEL_ID = "Kerassy/qwen-2.5-3b-smoltalk-sft"
+
+tokenizer = AutoTokenizer.from_pretrained(MODEL_ID)
+model = AutoModelForCausalLM.from_pretrained(
+    MODEL_ID, 
+    torch_dtype=torch.bfloat16 if torch.cuda.is_bf16_supported() else torch.float16,
+    device_map="auto"
+)
+
+pipe = pipeline("text-generation", model=model, tokenizer=tokenizer)
+
+messages = [
+    {"role": "user", "content": "Why is the sky blue?"}
+]
+
+formatted_prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
+
+outputs = pipe(
+    formatted_prompt, 
+    max_new_tokens=128, 
+    do_sample=True, 
+    temperature=0.7,
+    top_k=40,
+    clean_up_tokenization_spaces=False,
+    pad_token_id=tokenizer.pad_token_id,
+    eos_token_id=tokenizer.encode("<|end|>")[0] if "<|end|>" in tokenizer.get_vocab() else tokenizer.eos_token_id
+)
+
+print(outputs[0]['generated_text'])
