Not Diamond is an AI model router that automatically determines which LLM is best-suited to respond to any query, improving LLM output quality by combining multiple LLMs into a meta-model that learns when to call each LLM.

Key features

Maximize output quality: Not Diamond outperforms every foundation model on major evaluation benchmarks by always calling the best model for every prompt.
Reduce cost and latency: Make intelligent cost and latency tradeoffs to efficiently leverage smaller and cheaper models without degrading quality.
Personalized routing with feedback: Hyper-personalize routing to each individual end user in real-time based on their feedback.
Train your own custom router: Leverage your evaluation data to train your own custom routers optimized to your use case.
Python, TypeScript, and REST API support: Not Diamond is not a proxy and is easy to integrate across a variety of stacks.
