Meet Lumen Router — Smarter, Faster, and More Efficient AI Routing

When it comes to building AI products, choosing the right model for every request is everything. Some tasks need deep reasoning. Others just need speed. But until now, you had to choose one model and hope it worked for every scenario.

That's where Lumen Router changes the game.

What Is Lumen Router?

Lumen Router is Tensor AI's intelligent AI routing engine — designed to dynamically select and combine models to deliver the right balance of speed, accuracy, and cost for every task.

Instead of relying on a single LLM for all requests, Lumen Router analyzes context, complexity, and intent — then routes each request to the optimal model or model combination.

Save Money Without Sacrificing Quality

Not every prompt needs a massive, expensive reasoning model. Lumen Router automatically detects when a smaller, faster model can handle the task — such as summarizing text, extracting data, or generating short responses — saving you significant compute costs.

For heavier tasks that demand depth or reasoning, it scales up intelligently. You get enterprise-grade performance at startup-level efficiency — no manual tuning required.

Accuracy When It Matters Most

When precision is key — such as legal reasoning, strategy generation, or nuanced decision-making — Lumen Router intelligently escalates the task to a more sophisticated model.

This means your system always performs at its best: lean when it can, powerful when it must.

Combining Intelligence Across Multiple Models

Why settle for one perspective when you can have many?

Lumen Router can query multiple LLMs in parallel, aggregate their responses, and synthesize a unified, context-aware answer. This multi-model orchestration leads to richer, more balanced outputs — leveraging the strengths of each model to minimize blind spots and bias.

Imagine GPT, Claude, and Gemini all responding — and Lumen Router picking the best parts of each. That's the power of composite intelligence.

Faster Than Reasoning-Based Models

Because Lumen Router routes light tasks to lightweight models, your time to first character drops dramatically. You get near-instant responses for simple requests — while complex ones still benefit from optimized, parallel routing.

Your users experience snappier interfaces and shorter wait times, without any drop in quality.

The Core of Tensor AI

Lumen Router isn't just a feature — it's the beating heart of Tensor AI's platform. Every product built on Tensor AI — from the Unstructured Embeddings Engine to the PDF Document Builder — runs faster and smarter thanks to Lumen's adaptive intelligence.
