Tool profile
Multi-model routing and optimization platform that helps teams choose, evaluate, and automatically send AI workloads to the best-performing models for quality, latency, and cost.
Model routing
Not Diamond belongs in the catalog because it addresses a problem that serious AI product teams run into quickly: the best model is rarely the same across every prompt, task, or cost target. The official product story centers on routing, evaluation, prompt optimization, and model selection infrastructure rather than on being yet another wrapper around a single provider. That makes it relevant to teams that want AI stacks built around performance and economics instead of vendor loyalty.
It also deserves inclusion because the pricing page is public enough to evaluate responsibly. Not Diamond publishes an accessible entry point, usage allowances around routing and optimization, and commercial packaging for larger deployments. That is valuable in a premium catalog because buyers can understand both the architectural role and the commercial posture without having to treat the product as a pure demo-led black box.
Quick fit
Editorial take
Not Diamond should be framed as model decision infrastructure rather than as a general AI app builder. The main evaluation questions are whether routing quality is materially better than a simple default model strategy and how well the economics hold up at production volume.
