NotDiamond is an AI model router that automatically selects the best LLM for each specific task by learning which models perform best on different types of prompts. Instead of committing to a single model, NotDiamond analyzes your request and intelligently routes it to GPT-4o, Claude, Gemini, or other models based on historical performance data, delivering better results at lower cost. By routing simple tasks to efficient models and complex tasks to more capable ones, NotDiamond can reduce AI costs by 30-50% while maintaining or improving overall output quality.
