We’re excited to announce that Tetrate is launching Tetrate Agent Router Service, a managed LLM routing service that helps developers instantly achieve cost savings, improved model performance, and better troubleshooting—without the infrastructure overhead.
We set out to address the accessibility and user experience challenges of enterprise-ready AI gateways. The ecosystem is full of open source and proprietary AI gateways with varying features, but their presence hasn’t benefited the average developer much. It’s simply not practical for developers to spin up infrastructure, let alone build workflows and UX on top of that infrastructure to be productive.
Maybe your platform team is architecting a solution for a future release (possibly based on the proven Envoy AI Gateway), but why wait when you need cost savings, model resilience, and observability today?
For those who want the benefits of a powerful AI gateway but cannot deploy your own or have the patience to wait, Tetrate Agent Router Service is for you. Tetrate Agent Router Service acts like your personal fleet of Envoy AI Gateways, managed by the experts behind the Envoy project, with workflows that let you get all the benefits without any infrastructure overhead.
If you’re too impatient to read the blog, getting access and experimenting for yourself is just one click away. Otherwise, read on for an overview of Tetrate Agent Router Service.
LLM Routing Meets Model Optimization with Managed Infrastructure
Before diving into an illustrative example, let’s explore what you can do with Tetrate Agent Router Service.
Simplify your code and key management. Tetrate Agent Router Service provides a single unified entry point for all your LLM calls and handles provider keys on your behalf. Simply insert Tetrate’s OpenAI-compatible endpoint in your code, and you’re ready to go.
Optimize model consumption with intelligent routing. Tetrate Agent Router Service offers preset and customizable routing strategies. Whether you want to maximize savings, performance, or a blend of both, you can define how the service automatically switches between models based on availability or cost. This flexibility keeps your LLM-powered applications running smoothly even when underlying models are unreliable, while preventing runaway costs.
Gain visibility with built-in observability. Smart routing is just the start—the added observability is valuable even without optimization strategies. Once requests flow through Tetrate Agent Router Service, you can inspect each transaction in detail for troubleshooting.
Compare models with the integrated playground. To help you evaluate the right models for your use case, Tetrate Agent Router Service includes a built-in playground that lets you compare responses from different models side-by-side.
All these capabilities are available instantly without building or running any infrastructure.
Need enterprise guarantees? While users get shared tenancy by default, we can set up dedicated tenancy through our Enterprise Plan, with optional on-premises gateway deployment. Contact us to learn more.
Now let’s look at an example showcasing the features that make this possible.
Tetrate Agent Router Service In Action with Cline
Tetrate Agent Router Service offers flexible authentication options through Google and GitHub OAuth, providing developers with a familiar and secure way to access the service.
The dashboard intelligently adapts to your workflow. The context-aware interface shows the most relevant information for your current task—whether you’re making API requests or reviewing usage analytics.
Creating an API key is simple—the system automatically recommends optimal model configurations based on your priority: quality, speed, or cost efficiency. The generated keys work as drop-in replacements for OpenAI, requiring only a simple base URL change to https://api.router.tetrate.ai/v1.
The model catalog shows all available AI models across multiple providers, with key details like context windows and token pricing. This transparency helps you choose the right models for your routing strategies.
The playground feature lets you compare models side-by-side, testing the same prompt across different providers with real-time performance metrics. You can also run automated tests across multiple models to find the optimal configuration for your use case.
Every API request is logged with detailed metrics including models used, token counts, costs, and response times, providing full visibility into your AI operations.
The usage dashboard shows your AI gateway usage across four key metrics: total cost, total tokens, request volume, and latency. The time-series format helps you quickly analyze trends and identify usage patterns.
One Step Quick Start
You can try Tetrate Agent Router Service right now by signing up with your GitHub or Google account. Once registered, you can instantly use your favorite models with your preferred routing strategy via a Tetrate-managed routing service.
Pricing is simple and pay-as-you-go: you pay the model cost plus a 5% fee. Maintain a credit balance that auto-replenishes as you use it. New users get $5 free credit when signing up with a business email.
