Intelligent LLM Router

Cut your AI API
costs by up to 99%.
Same output quality.

Flywheel automatically routes each LLM request to the cheapest capable model — Flash for simple tasks, Pro for complex ones, with automatic escalation. One line of code. No lock-in.

Zero configuration.
Instant savings.

Change one line. Flywheel handles the rest — routing, escalation, fallback, and real-time tracking.

01 / Point
Change base_url

Point your existing OpenAI client at Flywheel. No new SDK, no migration. One string change and you're done.

02 / Route
Automatic dispatch

Each request is classified by complexity and type. Flash handles the simple ones. Pro and Premium are reserved for the rest.

03 / Learn
Gets smarter over time

Every routing decision and its outcome is logged. The system learns which model tiers work for your specific workload.

One line change.

OpenAI-compatible API. Works with LangChain, LlamaIndex, and every SDK that supports custom endpoints.

Built for production.

OpenAI-compatible

Drop-in replacement. Any framework that supports custom base_url works out of the box. No new dependencies.

Smart step detection

Automatically classifies requests as JSON, Cypher, or generic. Cheaper models handle structured tasks, complex reasoning gets escalated.

Telemetry-driven routing

Every outcome is logged. Routing decisions improve over time as the system learns what works for your workload.

Real-time dashboard

Live stats on requests, model mix, escalations, and cost savings. Always know exactly what's happening.

Automatic escalation

Failed or low-quality responses are automatically retried on the next model tier. No manual fallback logic needed.

Per-request tracking

Full audit log with model used, cost, savings, and validation outcome for every single request.

You only pay when
you save.

B2B subscription + a performance share on verified savings. If Flywheel doesn't cut your costs, there's nothing to share.

Base + % of savings

A fixed monthly platform fee covers access and infrastructure. The performance share applies only to verified, measurable savings tracked in real time on your dashboard — so our incentives are fully aligned with yours.

How is the savings share calculated? — We measure the delta between what you would have paid at your previous model tier (or top-tier equivalent) vs. what Flywheel actually spent. The share applies only to verified savings, tracked in real time and shown on your dashboard.
