🍳 Recipe Card Generator (T5-small + LoRA merged)

This model generates recipe cards (title, ingredients, and step-by-step directions) from a list of ingredients.
It is fine-tuned from t5-small using LoRA adapters and merged into a standalone checkpoint.

---

✨ Model Details

• Base model: t5-small
• Fine-tuning method: LoRA (rank=16, α=32, dropout=0.05, query/value projection layers)
• Dataset: Custom JSONL (input_text, target_text pairs), originally prepared from a Kaggle recipe dataset.
• Task: Text-to-Text Generation

📥 Usage

from transformers import T5ForConditionalGeneration, T5TokenizerFast

tok = T5TokenizerFast.from_pretrained("MahmutCanBoran/t5-recipe-card-en-lora-merged")
model = T5ForConditionalGeneration.from_pretrained("MahmutCanBoran/t5-recipe-card-en-lora-merged").eval()

prompt = "STRICT=yes | Ingredients: 1 cup sugar, 2 cups flour, 1/2 cup butter"
enc = tok(prompt, return_tensors="pt")
out = model.generate(
    **enc,
    max_new_tokens=160,
    num_beams=4,
    length_penalty=0.8,
    no_repeat_ngram_size=3
)
print(tok.decode(out[0], skip_special_tokens=True))

🔍 Example

Input:

STRICT=yes | Ingredients: 1 cup milk, 2 eggs, 1 cup flour


Output:

Title: Pancakes
Ingredients:
- 1 cup milk
- 2 eggs
- 1 cup flour
Directions:
1. Whisk eggs and milk.
2. Add flour slowly.
3. Cook on pan.
Time: 20-60 minutes
Servings: 4

## 🚀 Features
- **Input**: Raw ingredient list (e.g., `"chicken breast, yogurt, garlic, salt, pepper"`).  
- **Output**: Structured **recipe card** with:
  - Title suggestion 📝  
  - Ingredients (cleaned + normalized) 🧂  
  - Step-by-step cooking instructions 🍲  
  - Optional serving tips 🍽️  

- Supports **strict** and **flexible** generation modes:
  - `STRICT=yes` → Uses **only** given ingredients  
  - `STRICT=no` → Allows creative variations

⚠️ Limitations

Time/Servings fields are currently fixed values (20-60 minutes, Servings: 4).

Model may hallucinate instructions if STRICT=no mode is used (future work: add dataset with variable strictness).

Optimized for English outputs.
