+# SmolLM2-1.7B-ultrachat_200k
+
+Quantized Low Rank Adaptation (QLoRA) finetuned from HuggingFaceTB/SmolLM2-1.7B to UltraChat 200k dataset.
+
+Model trained as an exercise in LLM post-training.
+
+## Model Details
+
+- **Developed by:** Andrew Melbourne
+- **Model type:** Language Model
+- **License:** Apache 2.0
+- **Finetuned from model:** HuggingFaceTB/SmolLM2-1.7B
+
+### Model Sources
+
+Training and inference scripts are available here.
+- **Repository:** [SmolLM2-1.7B-ultrachat_200k on Github](https://github.com/Melbourneandrew/SmolLM2-1.7B-Ultrachat_200k?tab=readme-ov-file)
+
+## How to Get Started with the Model
+
+Use the code below to get started with the model.
+```python
+from peft import LoraConfig, get_peft_model, TaskType
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model = AutoModelForCausalLM.from_pretrained("M3LBY/SmolLM2-1.7B-ultrachat_200k")
+tokenizer = AutoTokenizer.from_pretrained("M3LBY/SmolLM2-1.7B-ultrachat_200k")
+
+messages = [{"role": "user", "content": "How far away is the sun?"}]
+prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
+inputs = tokenizer(prompt, return_tensors="pt")
+
+outputs = model.generate(**inputs)
+response = tokenizer.decode(outputs[0], skip_special_tokens=True)`
+print(response)
+```
+
+## Training Details
+
+The adapter model was trained using Supervised Fine-Tuning (SFT) with the following configuration:
+
+- Base model: SmolLM2-1.7B
+- Mixed precision: bfloat16
+- Learning rate: 2e-5 with linear scheduler
+- Warmup ratio: 0.1
+- Training epochs: 1
+- Effective batch size: 32
+- Sequence length: 512 tokens
+- Flash Attention 2 enabled
+
+Trained to a loss of 1.6965 after 6,496 steps.
+
+Elapsed time: 2 hours 37 minutes.
+
+Consumed ~22 Colab Compute Units for an estimated cost of $2.21 cents.
+
+## Evaluation
+
+<!-- This section describes the evaluation protocols and provides the results. -->
+
+
+## Citation [optional]
+
+<!-- If there is a paper or blog post introducing the model, the APA and Bibtex information for that should go in this section. -->
