Product Snapshot
Not Diamond is a model-routing and prompt-optimization platform for applications that use multiple LLM providers. It recommends which model to use for each input and can adapt prompts across candidate models.
What You Can Do With It
- Route requests with a pre-trained or custom router based on evaluation data.
- Adapt prompts across models and use prompt-optimization workflows.
- Integrate through Python, TypeScript, or REST API clients.
- Use client-side execution with zero data retention, local deployment, or VPC deployment options.
Why It Stands Out
It focuses on routing and prompt adaptation rather than offering a single model catalog.
Tradeoffs To Know
- Prompt adaptation is still in beta in the public docs.
- You still need your own upstream model provider keys and billing.
- The public pricing page is centered on API routing, so it is not a general chat product.
