What each one is

The product in its own terms, so the numbers below have context.

Not Diamond

Leader

A model routing service for coding agents that uses machine learning to predict and recommend the most cost-effective and accurate AI model for each request. Engineering teams typically achieve 20-40% cost savings without quality degradation through continuous learning from real usage patterns.

Independently observed

TensorZero

A self-hosted platform that combines deployment, monitoring, evaluation, and optimization for language model applications. It enables teams to manage multiple model providers through a single interface, measure performance across different configurations, and automatically improve routing strategies and prompts.
