What is Not Diamond?

Not Diamond intelligently predicts which model to use for each input, reducing costs while maintaining accuracy. The router integrates with existing harnesses and gateways, protecting against vendor lock-in. Purpose-built for long-horizon coding-agent workloads, it achieves 5%+ accuracy gains, 20%+ cost savings, and 2x faster development cycles.

How to use Not Diamond?

Install Not Diamond Code, set up the lightweight local proxy alongside your coding-agent harness, and start your first session. The router evaluates session context and recommends the optimal model and reasoning effort for each step.

Not Diamond Core Features

Intelligent Model Routing

Predicts which AI model to use for each input by evaluating payload semantics, KV cache state, implicit feedback signals, and session outcomes to recommend the optimal model for each step.

Coding Agent Optimization

Purpose-built for long-horizon coding-agent workloads. Selects the model and reasoning effort for each step of a session, using more capable models when they improve the outcome and more efficient models when additional intelligence is unlikely to add value.

Seamless Integration

Integrates securely with existing harnesses and gateway infrastructure, protecting against vendor lock-in. A lightweight local proxy runs alongside the coding-agent harness and computes derived metadata for routing.

Privacy-Preserving Routing

With privacy-preserving routing enabled, routing decisions are based solely on derived request metadata and locally computed features. Raw prompts, code, inputs, and outputs are never sent to Not Diamond.

Continuous Learning

Leverages reinforcement learning to continually learn from feedback signals and session outcomes, improving recommendations in real-time. Personalizes to each developer and transfers learnings across organizations.

Not Diamond Use Cases

Reducing inference costs for engineering teams using coding agents

Maintaining frontier-level quality across multi-model agent workflows

Optimizing model selection for long-horizon coding sessions

Enterprise AI teams requiring SOC-2 and ISO 27001 compliance

Not Diamond Frequently Asked Questions

What is intelligent model routing?

Intelligent model routing predicts which AI model to use for each prompt, maximizing accuracy while minimizing cost.

Is Not Diamond a gateway?

No. Not Diamond integrates with your existing gateway infrastructure. An AI gateway manages access to various models, while intelligent model routing determines which model to use on each prompt to get the best quality at the lowest cost.

What cost savings can we expect?

Teams using Not Diamond achieve at least 20-40% cost savings, and often more, without any degradation in quality relative to the frontier.

How does privacy-preserving routing work?

With privacy-preserving routing enabled, Not Diamond bases routing decisions solely on derived request metadata and locally computed features, meaning we never see your payload, inputs, or outputs. Enabling it has no negative impact on routing quality.

What is the added latency?

The average added per request latency of the router is 100-150ms.

Is Not Diamond SOC-2 compliant?

Yes. Not Diamond is SOC-2 and ISO 27001 compliant. Custom SLAs and 24/7 on-call support are provided for enterprise teams.
