MixRoute Smart Routing reads every request in real time with our in-house AI model, judging complexity and task type, then assigns the best-fit model from the pool you authorize. Across tens of thousands of real-world runs, it saves an average of 20–40% on API costs.

Eight in ten support questions are as simple as "How do I return this?" Yet every single one is billed at flagship-model rates.
Engineers pick one model per feature at launch, and nobody ever revisits the choice. Tasks keep changing. The model never does.
The model market shifts every month. Last month's best price-performance pick may already be beaten. No human keeps up.
The problem isn't the models. It's how they're assigned.
HOW IT WORKS
Step 1
Zero code changes. Create a Smart Routing API key in the console, swap out your current key, and keep sending requests in the same format.
client = OpenAI(
api_key="sk-your-current-key",
api_key="sk-smart-routing-key",
base_url="https://api.mixroute.ai/v1"
)
# request format unchangedStep 2
Our in-house routing model reads each request on the fly and judges its complexity and task type. It supports a 1M-token context window, so even the longest requests are fully assessed. Read-only, never stored: content is processed in memory and cleared the moment triage ends, fully in line with MixRoute's zero data retention policy.
Step 3
From the pool you authorize, the router picks the model best suited to the request. Your full context passes through untouched: no rewriting, no compression, no truncation. The answer still comes from the real model.
Full context passes through untouched. Answers come from the real model.
CONTROL
Fully automatic black-box routers take the model decision out of your hands. MixRoute works the other way around: Smart Routing only ever operates inside boundaries you define.
Give every key its own model pool in the console. Which model endpoints can be assigned is entirely up to you: only the ones you trust, that fit your compliance rules and your budget.
Set usage limits on every key; anything beyond them is blocked. No runaway requests, no runaway bills.

MEASURED RESULTS
We tested Smart Routing's assignment decisions across tens of thousands of real tasks: the average saving came out at 20–40% of API cost. The exact figure depends on the vendor mix in your model pool, which is why we quote a measured range instead of a marketing number.

Estimated from the average range measured across 10,000+ runs. Actual savings vary with your model pool.
USE CASES
Scenario 01
Masses of repetitive, simple questions are Smart Routing's biggest source of savings. Easy ones go to light models, hard ones auto-upgrade. Customers never notice. Your bill does.
Biggest savingsScenario 02
Policy lookups, document search, meeting summaries: most requests don't need a flagship model, but the occasional deep dive does. The router tells them apart, so you don't have to.
Depth, auto-detectedScenario 03
You can't predict what users will ask, and simple and complex arrive interleaved. Instead of betting everything on one model, give each request exactly the model it needs.
Right-sized requestsScenario 04
Completions and small functions run fast and cheap on light models; cross-file refactors and gnarly debugging auto-upgrade to a flagship. Engineers write code. The router picks models.

5%
After the free period, we charge a 5% service fee only on requests that actually go through Smart Routing. Requests on regular keys are never charged.

You save far more than you pay. That's the entire reason this exists.
FAQ
Yes. Triage adds one extra step, and the time varies with request length. It’s a trade: a little time for 20–40% off your costs. For latency-critical endpoints, use a regular key to call a specific model directly and skip the router.
It reads, it never stores. Request content is classified in memory in real time, cleared immediately afterward, and passed through to the target model untouched. Nothing is written to persistent storage, consistent with MixRoute’s zero data retention policy.
Your model pool is the insurance: the router only ever chooses among models you’ve authorized and never assigns anything outside the pool. If some traffic must always hit one specific model, create a separate regular key for it and call that model directly.
One word: control. Most auto-routers are a total black box where the platform decides everything. MixRoute’s Smart Routing runs inside a model pool you define, with zero data retention and a savings dashboard. You always know where the money is saved and where your data goes.
No. Create a Smart Routing API key in the console and swap it in for your current key. The API call format stays exactly the same.
Free for a limited time. Once the free period ends, only requests that go through Smart Routing are charged a 5% service fee on that request’s cost. It’s deducted from your credit balance, with a transparent, itemized bill.
