Bawarchi Recipe Generation Model

Role-aware fine-tuned Llama 3.2 3B for cuisine-context recipe generation

Model Description

Bawarchi is a recipe generation model that understands ingredient roles and adapts recipes based on cuisine context. Fine-tuned from Llama 3.2 3B using LoRA with a novel curriculum learning approach over 335K recipes, plus role-aware extension training on 1K curated examples.

Key Capabilities:

• Cuisine-context switching: Same ingredients → different dishes by cuisine (e.g., chicken + tortilla = tacos in Mexican, roti wrap in Indian)
• Ingredient role reasoning: Understands ingredients serve interchangeable roles (chicken ↔ paneer as protein, pasta ↔ rice as carb)
• Intelligent adaptation: Suggests culturally appropriate substitutions

Example:

Input: Create Indian recipe using chicken, tomato, tortilla
Output: "Chicken Tikka Roti Wrap - Note: Tortilla detected. For authentic Indian cuisine, 
consider using roti or naan instead as the flatbread base..."

• Developed by: Tushar Jaju
• Model type: Causal Language Model (Recipe Generation)
• Language: English
• License: MIT
• Base Model: meta-llama/Llama-3.2-3B-Instruct
• Fine-tuning Method: LoRA (Low-Rank Adaptation)

Model Details

Architecture

• Base: Llama 3.2 3B (3 billion parameters)
• Fine-tuning: LoRA adapters (trainable parameters: ~37M)
• LoRA Configuration:
  • Phase 1-3: r=64, alpha=128, dropout=0.05
  • Role-aware: r=16, alpha=32, dropout=0.05
  • Target modules: [q_proj, k_proj, v_proj, o_proj]
• Precision: fp16 (mixed precision training)
• Context Length: 2048 tokens

Training Strategy

Curriculum Learning (Phase 1-3):

1. Phase 1 - Simple Recipes: Basic structure (ingredients → steps)

   • 100K examples, 3 epochs
   • Learning rate: 2e-4

2. Phase 2 - Complex Recipes: Multi-step reasoning, timing, techniques

   • 185K examples, 3 epochs
   • Learning rate: 2e-4

3. Phase 3 - Fusion Recipes: Cultural adaptation, substitution logic

   • 50K examples, 5 epochs
   • Learning rate: 1e-4

Role-Aware Extension:

• 1K curated examples demonstrating ingredient role reasoning
• 2 epochs, learning rate: 1e-4
• Teaches cuisine-context switching

Total Training Time: 13 hours (11h Phase 1-3 + 2h role-aware)

Performance

Cuisine-Context Validation:

• Roti + chicken → Indian-style preparation (not Mexican)
• Tortilla + paneer → Mexican-style usage (not Indian)
• Pasta in Indian request → Suggests rice/roti substitution
• Ingredient role understanding across cultures

Intended Use

Primary Use Case

Generate cuisine-aware recipes from a list of available ingredients with intelligent adaptation based on cultural context.

Supported Cuisines:

• Indian
• Mexican
• Italian
• Asian (general)
• Fusion
• General/International

Input Format:

Create a {difficulty}-level {cuisine} recipe using: {ingredient_list}

Output Format:

• Recipe title
• Ingredient list with quantities
• Step-by-step instructions
• Cooking time and servings
• (Optional) Substitution suggestions

Downstream Applications

• Recipe recommendation systems
• Meal planning applications
• Cooking assistants
• Dietary adaptation tools
• Culinary education platforms

Out-of-Scope Use

Not suitable for:

• Medical/dietary advice without professional validation
• Nutrition calculation (no nutritional analysis capabilities)
• Allergen detection (model may miss allergens)
• Commercial recipe databases (license implications)
• Real-time video-based cooking guidance

Evaluation

Test Set Performance

Metrics on 1000-example test set:

• Accuracy (structure + coherence): 74.1%
• Loss: 0.997
• BLEU-4: ~0.45
• Perplexity: ~2.71

Limitations

Technical:

• English language only
• Trained primarily on Western and South Asian cuisines
• May hallucinate rare ingredients or techniques

Data Bias:

• Over-representation of general/international cuisine (89.7%)
• Under-representation of regional/specialty cuisines
• Bias toward common ingredients (chicken, tomato, onion)

Safety:

• Does not validate food safety (temperatures, allergens)
• May suggest inappropriate ingredient combinations
• No nutritional information or dietary restriction handling

Bias and Ethics

Known Biases:

• Cultural: Western/Indian recipes over-represented
• Ingredient: Common ingredients favored over specialty items
• Complexity: Bias toward medium-complexity recipes

Ethical Considerations:

• Recipe sources (Food.com) licensed under CC-BY-SA
• Model outputs should be validated for food safety
• Dietary restrictions require professional verification
• Allergen detection not reliable - always verify

Recommendations:

• Validate recipes with culinary experts for safety
• Cross-check allergen information independently
• Consider cultural sensitivity when adapting traditional recipes
• Use as a creative tool, not authoritative source

ompute Efficiency:

• Model size: 3B parameters (efficient for performance)
• LoRA fine-tuning: 37M trainable (vs. 3B full fine-tuning)
• Mixed precision: 2x memory efficiency
• Curriculum learning: Converged in 13h (vs. naive ~24h)
