Router and Models

Router

The power behind Arcee Conductor comes in the form of an ultra-lightweight model router which classifies and routes prompts to the most cost-effective model which can accurately complete the request.

The router is 150M parameter, custom architecture model which classifies based on four primary categories: task type, domain, complexity, and language. The categories for each class consist of:

• Task Type: Analytical, Classification, Code Generation, Extraction, Math, QA, Rewrite, Summarization, Text Generation, Other

• Domain: Adult, Arts and Entertainment, Autos and Vehicles, Beauty and Fitness, Books and Literature, Business and Industrial, Computers and Electronics, Finance, Food and Drink, Games, Health, Hobbies and Leisure, Home and Garden, Internet and Telecom, Jobs and Eduction, Law and Government, News, Online Communities, People and Society, Pets and Animals, Real Estate, Science, Sensitive Subjects, Shopping, Sports, Travel and Transportation

• Complexity: 1-10

• Language: Arabic, Bengali, Cantonese, Filipino, French, German, Hindi, Italian, Korean, Mandarin, Marathi, Portuguese, Russian, Spanish, Tamil, Telugu

Due to the exceptionally small parameter count and custom architecture, the router executes in roughly 150ms resulting in negligible impact to user experience, when considering time to first token.
