NemoRouter
What is NemoRouter?
NemoRouter is a managed LLM gateway for product and platform teams that routes requests before any provider call, reserving credit, applying inline guardrails, and using smart routing with fallback and retry. It exposes an OpenAI-compatible API and includes budget enforcement, prompt templates, observability, and enterprise controls like multi-tenancy, RBAC, and audit logging. It serves 263+ models across 6+ providers and is used by GitHub, Notion, Langfuse, Datadog, and Slack. Plans start with Pay as you go at $5 to start, then Pro at $50/mo or $500/yr in credits, with Enterprise custom.

What does NemoRouter do?
NemoRouter routes LLM requests through a managed gateway that sits in the request path before any provider call. It reserves credit before execution, applies guardrails inline, and uses smart routing with fallback and retry so long-running agent workflows can keep moving when a provider degrades. The OpenAI-compatible API keeps integration simple, while budget enforcement, prompt templates, and observability give teams control over spend and behavior without adding infrastructure. At scale, the platform serves 263+ models across 6+ providers with 99.9% uptime and under 95ms latency. The routing layer is fully managed, so there is no plugin sprawl or operator overhead, and the enterprise layer adds multi-tenancy, RBAC, and audit logging on top. NemoRouter says every request is authed and scoped before it reaches a provider, with virtual keys only and no customer paths to master keys. Customers and design partners include GitHub, Notion, Langfuse, Datadog, and Slack.
Why use NemoRouter?
- Every feature ships on every plan, so teams do not have to buy up for guardrails, RBAC, or audit logs.
- Budget checks happen before the call runs, which helps stop runaway agent loops from turning into surprise bills.
- One OpenAI-compatible endpoint covers 263+ models across 6+ providers, reducing provider lock-in and key sprawl.
- Smart routing, fallback, and retry keep agent workflows alive when a provider slows down or fails.
- The managed gateway adds multi-tenancy and row-level isolation without asking teams to run routing infrastructure themselves.
Who is NemoRouter for?
- Product teams shipping AI features that need per-key budgets and one governed model gateway.
- Agent and workflow builders who need fallback chains and retry policies for long-running runs.
- Startups moving fast and want pay-as-you-go access without feature gating.
- Platform and infra teams that need org, team, and key scoping with audit trails.
- Security-conscious teams that need inline guardrails, PII redaction, and access control.
What are NemoRouter's key features?
Budget enforcement
Set spend limits and stop overruns with budget controls and cost vs usage tracking, backed by daily aggregates and one-bill reporting.
Governance, included
Apply guardrails on every request with audit logging and RBAC, so teams can control usage and review activity across the gateway.
One key, every provider
Use a single NemoRouter API key and OpenAI-compatible endpoint to reach 263+ models across 6+ providers without managing provider keys.
Cost vs usage
Compare spend against usage with transparent per-million-token pricing, including $5.00/M input and $30.00/M output examples for planning.
Smart Routing
Route, fall back, and retry requests automatically across 263+ models, helping maintain <95ms latency and 99.9% uptime targets.
Guardrails
Enforce request-level protections with guardrails plus PII handling, and connect monitoring through Langfuse, Datadog, or Slack.
Model Catalog
Browse 263 models with 128K-token and 1M-token context options, then choose providers like OpenAI, Anthropic, Google Vertex AI, or AWS Bedrock.
RBAC
Manage teams with 4 roles, SSO/SAML, and audit logging, giving administrators tighter access control across shared model usage.

What are NemoRouter's use cases?
Product teams control model spend
Product teams shipping AI features use NemoRouter to keep per-key spend predictable while routing requests through one governed gateway. They rely on Budget enforcement and Cost & Usage Tracking to cap runaway usage, then use Model Catalog to choose the right model without juggling provider keys.
Agent builders add fallback chains
Agent and workflow builders use NemoRouter to keep long-running runs alive when a model slows down or fails. They combine Smart Routing with Routing, fallback & retry to switch providers automatically, so customer-facing workflows finish instead of stalling mid-task.
Security teams redact sensitive prompts
Security-conscious teams use NemoRouter to put Guardrails + PII in front of every request before it reaches a model. With RBAC and Audit logging, they can restrict access, trace usage by team, and reduce the risk of sensitive data leaking into prompts.
Platform teams govern one gateway
Platform and infra teams use NemoRouter as a managed LLM gateway for org, team, and key scoping across shared AI infrastructure. They pair RBAC & team management with Governance, included to standardize access, simplify oversight, and keep every model behind one API Key.
How does NemoRouter work?
- Connect your first provider or model source, then point your app at NemoRouter's single endpoint. Use One key, every provider to replace scattered provider credentials with one API key.
- Choose models in the Model Catalog and set routing preferences for each workload. Turn on Smart Routing so requests can move across providers without changing your application code.
- Define limits with Budget enforcement and Budget Controls for each key, team, or project. Review Cost vs usage to spot spikes early and keep spend aligned with product plans.
- Enable Guardrails and Guardrails + PII to filter prompts and responses before they leave the gateway. Add RBAC so only approved teammates can change policies or access sensitive workloads.
- Monitor traffic in Observability, then refine routing, budgets, and model choices as usage grows. Use Audit logging and Team Management to keep governance intact across ongoing releases.

Editor's read
Check whether the Pro plan's higher throughput and priority routing are enough for your workload before you commit to reserved capacity. If your agent runs depend on strict latency or volume guarantees, confirm whether Enterprise's dedicated capacity and custom SLA are the real requirement.
