Not Diamond

Not Diamond is an intelligent model router for teams building AI agents, coding agents, and multi-model applications. Instead of hardcoding one default model for every request, it predicts which model should handle each input based on quality, cost, latency, or a custom router trained on your own evaluation data. The platform is useful for engineering teams that already use several frontier and open models across production workflows. Not Diamond can recommend models through its API, Python SDK, TypeScript client, and REST endpoints, while letting your own gateway or orchestration layer make the final model call. For agent builders, the main value is better model selection without manually testing every prompt across every provider. Teams can use pre-trained routing, train custom routers, optimize prompts, add fallback rerouting, and reduce waste from sending simple tasks to expensive models. Not Diamond is best for teams that care about LLM cost control, model quality, routing observability, and production reliability. It is not a general chatbot marketplace. It is infrastructure for developers who need smarter model selection inside real AI products.
