## Overview

Not Diamond tackles a familiar problem for teams building coding agents: choosing among dozens of models, reasoning levels and context strategies is hard, so most developers simply default to the strongest (and priciest) model for everything. Not Diamond's router analyzes payload semantics, KV cache state, implicit feedback signals, session outcomes, sub-agent structure and compaction events, then recommends both a model and a reasoning budget for each step in a session.

The company stresses that it is a router, not a gateway. It integrates with the gateway and agent harness you already run, which helps avoid vendor lock-in and keeps execution inside your own infrastructure. Recommendations can also use privacy-preserving routing, where decisions are based on derived metadata and locally computed features so your prompts and outputs are never exposed.

Not Diamond reports at least 20-40% cost savings for typical teams with no measurable quality loss versus the frontier, and shares customer stories such as OpenRouter, Replicated and Rootly citing accuracy gains after adoption. It is SOC 2 and ISO 27001 compliant and offers SLAs plus around-the-clock support for enterprise customers, with continuous reinforcement learning that improves recommendations over time.

## Pricing & Plans

Pay-as-you-go at $0.05 per million tokens routed, with multi-harness and multi-provider support plus a savings and usage dashboard. An Enterprise tier adds volume discounts, organization-wide analytics, admin controls, SSO via SAML and privacy-preserving deployment. Larger teams can request access or book a demo.

## Key Features & Capabilities

- **Intelligent per-request routing:** Predicts the best model and reasoning effort for each step of a session by weighing prompt semantics, cache state, sub-agent structure and past session outcomes.
- **Harness and gateway agnostic:** Works alongside the coding-agent harness and model gateway you already use, so recommendations execute inside your own stack without locking you into a single provider.
- **Privacy-preserving routing:** Can route using only derived request metadata and locally computed features, so Not Diamond never sees your payloads, inputs or outputs.
- **Continuous learning:** Reinforcement learning from feedback signals and session results personalizes recommendations per developer and transfers learnings across an organization.
- **Savings and usage dashboard:** Tracks routing spend and savings so teams can measure the cost impact and verify quality is maintained.

## Primary Use Cases

- **Cut coding-agent inference spend (Platform / Infra engineer):** Route long-horizon coding agent traffic to the cheapest adequate model per step, targeting documented savings of 20-40% or more.
- **Improve accuracy without changing models (AI product lead):** Use routing plus reasoning-effort selection to lift benchmark accuracy on workflows such as SRE incident response, as reported by customers like Rootly.
- **Avoid vendor lock-in (Enterprise architect):** Keep your existing gateway and harness while adding intelligent routing, with SAML SSO, admin controls and privacy-preserving deployment options.
- **Optimize Claude Code sessions (Developer):** Run Not Diamond alongside Anthropic models to reduce spend on coding agents while staying within commercial usage terms.

## Strengths

- Purpose-built for long-horizon coding agents rather than generic chat
- Integrates with existing gateways and harnesses instead of replacing them
- Documented 20-40% cost savings with reports of maintained or improved quality
- SOC 2 and ISO 27001 compliance with SSO and privacy-preserving routing

## Limitations

- Requires a gateway and harness setup, so not a plug-and-play standalone product
- No published free tier; pay-as-you-go and enterprise access may need a demo or application
- Value depends heavily on how much multi-model overhead your workload already has

## Frequently Asked Questions

### Is Not Diamond a model gateway?
No. Not Diamond is a routing layer that sits alongside your existing gateway. The gateway manages access to models; Not Diamond decides which model and reasoning effort to use on each request.

### How much does it cost?
Pay-as-you-go is listed at $0.05 per million tokens routed, which the company notes is cheaper than the cheapest LLM. Enterprise plans with volume discounts are available on request.

### Does privacy-preserving routing reduce quality?
Not Diamond states that enabling privacy-preserving routing has no negative impact on routing quality, because decisions rely on derived metadata and locally computed features rather than raw payloads.

### How much latency does routing add?
The average added latency per request is cited as roughly 100-150ms.

### What is Not Diamond's monthly traffic and growth trend?
Not Diamond currently receives 29.24K monthly visits, with a month-over-month traffic change of +5.9K (+25.3% growth rate). Its primary source market is Australia (42% share), including 12.47K direct visits/mo and — organic search visits/mo.
