+# GPT‑2 Fine‑tuned on English Quotes
+
+## Model Description
+
+This model is a fine‑tuned version of [GPT‑2 small](https://huggingface.co/gpt2) (124M parameters) on the [Abirate/english_quotes](https://huggingface.co/datasets/Abirate/english_quotes) dataset.  
+The goal is to generate text in the style of philosophical or literary quotes, including the author’s name.
+
+**⚠️ This model was created for educational and research purposes only. It is not intended for production use.**  
+It demonstrates full fine‑tuning of a causal language model on a small dataset and the improvements in generation quality compared to the base model.
+
+**Base model**: `gpt2`  
+**Task**: Causal language modelling (text generation)  
+**Fine‑tuning type**: Full fine‑tuning (all parameters updated)
+
+## Intended Uses & Limitations
+
+### Direct Use (Research / Experimentation)
+
+You can use this model to generate short quotes given a prompt. The model expects prompts to start with the special token `<|startoftext|>` and will learn to produce a quote followed by an author and the `<|endoftext|>` token.
+
+**Example**:
+```python
+from transformers import pipeline
+
+generator = pipeline("text-generation", model="lorcannrauzduel/gpt2-citations")
+output = generator("<|startoftext|> The secret to", max_new_tokens=50, do_sample=True)
+print(output[0]['generated_text'])
+```
+
+### Limitations
+
+- The model is small (124M) and was trained on only ~2,500 quotes. It may sometimes produce repetitive or nonsensical outputs.
+- It only generates English text.
+- It does not have factual knowledge about the authors; it merely mimics the style of the training quotes.
+- **Not suitable for any commercial or critical application.**
+
+## Training Details
+
+### Training Data
+
+- **Dataset**: [Abirate/english_quotes](https://huggingface.co/datasets/Abirate/english_quotes) – 2,508 quotes, each with a `quote` and an `author` field.
+- **Preprocessing**: Each example was formatted as:
+  ```
+  <|startoftext|> "quote" — author <|endoftext|>
+  ```
+  The special tokens help the model learn where a quote starts and ends.
+
+### Training Procedure
+
+The model was trained for 5 epochs using the Hugging Face `Trainer` with the following hyperparameters:
+
+| Hyperparameter          | Value |
+|------------------------|-------|
+| Learning rate          | 5e-5  |
+| Batch size (per device)| 8     |
+| Gradient accumulation  | 2     |
+| Effective batch size   | 16    |
+| Warmup steps           | 100   |
+| Weight decay           | 0.01  |
+| Optimizer              | AdamW |
+| Precision              | fp16  |
+| Max sequence length    | 128   |
+| Training steps         | 1410  |
+
+**Hardware**: NVIDIA Tesla T4 (15 GB VRAM) on Google Colab / Kaggle.  
+**Training time**: ~5 minutes.
+
+### Evaluation Results
+
+The final training loss was **2.506**, corresponding to a perplexity of **12.26**.  
+Validation loss stagnated around 2.30, indicating a slight overfitting after 3‑4 epochs – acceptable for a small generative model.
+
+## How to Use the Model
+
+### With 🤗 Transformers
+
+```python
+from transformers import AutoTokenizer, AutoModelForCausalLM
+
+tokenizer = AutoTokenizer.from_pretrained("lorcannrauzduel/gpt2-citations")
+model = AutoModelForCausalLM.from_pretrained("lorcannrauzduel/gpt2-citations")
+
+prompt = "<|startoftext|> Life is"
+inputs = tokenizer(prompt, return_tensors="pt")
+output = model.generate(**inputs, max_new_tokens=50, do_sample=True, temperature=0.9)
+print(tokenizer.decode(output[0], skip_special_tokens=False))
+```
+
+### With Pipeline
+
+```python
+from transformers import pipeline
+
+pipe = pipeline("text-generation", model="lorcannrauzduel/gpt2-citations")
+print(pipe("<|startoftext|> You can never", max_new_tokens=50)[0]['generated_text'])
+```
+
+### With vLLM (for high‑throughput inference)
+
+```bash
+pip install vllm
+vllm serve "lorcannrauzduel/gpt2-citations"
+```
+
+Then query with curl:
+
+```bash
+curl -X POST "http://localhost:8000/v1/completions" \
+     -H "Content-Type: application/json" \
+     --data '{
+         "model": "lorcannrauzduel/gpt2-citations",
+         "prompt": "<|startoftext|> The secret to",
+         "max_tokens": 50,
+         "temperature": 0.8
+     }'
+```
+
+### With Ollama (local deployment after GGUF conversion)
+
+1. Download the GGUF version from the repository (if available) or convert it yourself using `llama.cpp`.
+2. Create a `Modelfile`:
+   ```
+   FROM ./gpt2-citations-q4km.gguf
+   SYSTEM "You are a quote generator."
+   PARAMETER temperature 0.8
+   PARAMETER stop "<|endoftext|>"
+   ```
+3. Import and run:
+   ```bash
+   ollama create gpt2-citations -f Modelfile
+   ollama run gpt2-citations "<|startoftext|> Life is"
+   ```
+
+## Model Comparison (Base vs Fine‑tuned)
+
+| Prompt | GPT‑2 Base (no fine‑tuning) | GPT‑2 Fine‑tuned |
+|--------|-----------------------------|------------------|
+| `<|startoftext|> The secret to` | "The secret to making the most of your life... [[...]]" | "The secret to happiness is to trust your instincts rather than your brain.” — Albert Einstein" |
+| `<|startoftext|> Life is` | "Life is precious and life is precious..." | "Life is full of opportunities, but few opportunities are worth the time..." — Jodi Picoult |
+| `<|startoftext|> You can never` | "You can never get around to finding out what you want..." | "You can never lose your way because you are still thinking about the things you've done..." |
+
+The fine‑tuned model consistently produces coherent quotes with an author attribution, while the base model generates irrelevant or repetitive text.
+
+## Environmental Impact
+
+Training was performed on a cloud GPU (Tesla T4) for about 5 minutes. Estimated CO₂ emissions are negligible (< 0.01 kg CO₂eq).
