Advanced Multi-Model Orchestrator with Parent LLM Reasoning

🚀 A sophisticated multi-model orchestration system that uses a parent LLM to intelligently reason about and route tasks to the most appropriate child models.

🧠 The Innovation

Unlike traditional orchestrators that use simple heuristics or keyword matching, this system employs a parent LLM (distilgpt2) to analyze user requests and make intelligent routing decisions based on reasoning rather than pattern matching.

Parent LLM Prompt:

You are a router. Analyze this user request and choose the best model:
- "TEXT" for text summarization, Q&A, or text processing
- "CAPTION" for describing images
- "TEXT2IMG" for generating images from text
- "MULTIMODAL" for complex tasks requiring multiple models

Respond only with one keyword: TEXT, CAPTION, TEXT2IMG, or MULTIMODAL.

User request: <USER_PROMPT>
Response:

📦 Installation

pip install git+https://huggingface.co/kunaliitkgp09/multi-model-orchestrator

🚀 Quick Start

import asyncio
from advanced_orchestrator import AdvancedMultiModelOrchestrator

async def main():
    # Initialize the orchestrator
    orchestrator = AdvancedMultiModelOrchestrator(parent_model_name="distilgpt2")
    
    # Process a request
    result = await orchestrator.process_request("Generate an image of a peaceful forest")
    
    print(f"Task Type: {result.task_type.value}")
    print(f"Confidence: {result.confidence:.2f}")
    print(f"Output: {result.output}")
    print(f"Processing Time: {result.processing_time:.2f}s")

asyncio.run(main())

📋 Usage Examples

Basic Request Processing

# Text processing request
result = await orchestrator.process_request("What is machine learning?")
# Parent LLM routes to TEXT model

# Image captioning request  
result = await orchestrator.process_request("Describe this image of a sunset")
# Parent LLM routes to CAPTION model

# Text-to-image request
result = await orchestrator.process_request("Generate an image of a futuristic city")
# Parent LLM routes to TEXT2IMG model

Multimodal Processing

# Process complex multimodal requests
results = await orchestrator.process_multimodal_request(
    image_path="sample_image.jpg",
    text_prompt="A serene landscape with mountains"
)

# Results contain both caption and generated image
caption_result = results["caption"]
generated_image_result = results["generated_image"]

Performance Monitoring

# Get performance statistics
stats = orchestrator.get_performance_stats()
print(f"Total Tasks: {stats['total_tasks']}")
print(f"Success Rate: {stats['success_rate']:.1%}")
print(f"Average Processing Time: {stats['average_processing_time']:.2f}s")

# Get task history
history = orchestrator.get_task_history()
for task in history:
    print(f"{task.task_type.value}: {task.input_data[:50]}...")

🔧 Configuration

Model Configuration

from advanced_orchestrator import ModelConfig, TaskType

    name="your-custom-model",
    model_type=TaskType.TEXT,
    device="cuda",
    max_length=512,
    temperature=0.7
)

Parent LLM Configuration

# Use different parent LLM
orchestrator = AdvancedMultiModelOrchestrator(
    parent_model_name="gpt2"  # or any other model
)
