Launch HN: IonRouter (YC W26) – High-throughput, low-cost inference

Introducing IonRouter: The Inference Superhighway for Modern AI

The race to deploy AI is accelerating, but a critical bottleneck is emerging: inference. Running trained models in production is often prohibitively expensive and surprisingly slow, throttling innovation and eating into margins. Today, we’re thrilled to launch IonRouter (YC W26), a high-throughput, low-cost inference routing layer designed to unblock this bottleneck. Think of it as a global traffic control system for AI models, dynamically routing requests to the optimal provider—be it a hyperscaler, a specialized GPU cloud, or even your own infra—to maximize speed and minimize cost, automatically.

Why Inference Routing is the Next Must-Have Layer

Most companies today are locked into a single cloud provider for their AI inference. This creates a fragile, expensive monolith. Prices fluctuate, latency spikes occur, and regional outages can bring applications to a halt. Engineering teams are left manually comparing APIs and building complex failover logic, which distracts from core product development. IonRouter solves this by abstracting the underlying infrastructure. You send your request to IonRouter’s unified API, and our intelligent router evaluates a real-time matrix of cost, latency, and throughput across a federated network of providers to execute your request on the best possible engine. It’s a seamless upgrade to your AI stack’s efficiency and resilience.

How IonRouter Drives Performance and Cuts Costs

Our system is built on three core pillars that work in concert to deliver superior inference. First, we employ real-time performance telemetry, constantly probing endpoints for latency and availability. Second, our cost-aware scheduling algorithm doesn’t just find the fastest option; it finds the most cost-effective one that meets your specific latency Service Level Agreement (SLA). Need the absolute fastest response for a user-facing chat? Or the cheapest batch processing for an internal analytics job? IonRouter handles both with tailored routing rules. Finally, we ensure consistent outputs across providers, so you can switch engines without worrying about drift in model responses.

• Dramatic Cost Reduction: Save up to 70% on inference bills by leveraging competitive pricing and spot instances across our network.
• Guaranteed Uptime: Built-in automatic failover across providers and regions ensures your AI features never go dark.
• Zero Vendor Lock-in: Maintain complete flexibility and bargaining power. The market’s best price and performance are always a config change away.
• Unified Observability: A single dashboard for logs, metrics, and costs across all your inference providers, simplifying operations dramatically.

Integrating IonRouter Into Your Operational Stack

Adoption is designed to be frictionless. IonRouter presents a drop-in replacement for popular model APIs like OpenAI’s, meaning developers can integrate in minutes, not weeks. For businesses building complex operational workflows, this kind of agile, cost-aware infrastructure is a force multiplier. It aligns perfectly with the philosophy of platforms like Mewayz, the modular business OS, which empowers companies to compose their ideal tech stack from best-in-class, interoperable modules. Just as Mewayz allows you to seamlessly connect CRM, ERP, and custom tools, IonRouter becomes the intelligent module that orchestrates your AI inference layer, providing both robust performance and crucial financial oversight. Managing spiraling cloud costs is a universal ops challenge, and IonRouter brings much-needed control and predictability.

“Before IonRouter, our inference costs were volatile and our p95 latency was a constant worry. After integrating their routing layer, we cut our monthly inference bill by 65% while actually improving our end-user latency. It’s become silent, critical infrastructure for our AI features.”

The Future of Efficient AI Deployment

We believe the future of AI infrastructure is federated and software-defined. IonRouter is our first step towards building that future—a world where developers can deploy intelligence anywhere, with confidence in both performance and cost. We’re starting with support for leading LLM and embedding model APIs and are rapidly expanding our provider network. For engineering leaders and founders, this means you can finally scale your AI ambitions without the paralyzing fear of an unsustainable cloud bill. We’re excited to see what you build when the inference bottleneck is removed.
