Cheap and strong is empty
No graded pass sits in the cheap-and-strong region. The routers that are accurate are not the cheap ones.
The AI Evaluation Engine
for the Agentic Era
The engine benchmarks models, agents, verticals, and now routers. Quality, cost, and speed come from the same evidence.
New Router benchmark is live (7 commercial routers). None beat calling a mid-priced model on both quality and cost.
AutoBench Router Benchmark
7 commercial routers, 17 passes, scored on the 252-question matrix from 2026-08-29. Accuracy is the share of questions where the chosen model is statistically as good as the best available answer.
5 of 17 passes collapsed
A collapsed pass sends at least 90% of questions to one model. It is a constant, not a router.
Same-pick median 0
Across 59 cross-vendor pairs, the median share of questions where two passes name the same model is 0.
Quality versus cost
Horizontal dashes are Always-Sol, Always-Luna, and Random. The vertical dash is Random's cost. Amber points collapsed onto one model. Cost is USD per question, on a log scale.
Accuracy is the share of questions where the chosen model is statistically as good as the best available answer.
Routing without measurement is guessing
One engine writes the questions, collects the answers, and scores them. Benchmarks and routing evidence come from that same record.
Live
Benchmarks
Models, agents, and verticals, scored on quality, cost, and speed. Each run writes new questions, so the board is hard to game.

Routing
The Router Benchmark grades commercial routers on a frozen answer matrix. A trained router, built on the same evidence, is next.

Private model runs, a router graded on your traffic, or a router built for your own model pool.

HOW IT WORKS
One engine writes the questions, collects the answers, and scores them. Benchmarks and routing evidence are two readings of that record.
01 Generate
The engine writes new, difficulty-balanced questions. There is no fixed public test set.
02 Answer
Each model answers. Every answer carries its billed cost and its generation time.
03 Judge
A committee of models scores every answer. Consensus is the signal.
04 Use the evidence
The same run is a benchmark report, and the trace a router can be graded on.
Validation: Proven Accuracy at Scale

Benchmark models on your use cases
Run the engine on your own tasks and data. You get quality, cost, and latency for the models you actually call, including sentiment analysis, document summarization, and customer support.
Grade routers on your traffic
The public Router Benchmark scores commercial routers on a frozen answer matrix. The same method can grade a router on your own traffic. The latest public model run correlates 88.13% with the Artificial Analysis Intelligence Index.
A router for your mix
When the public board is not the question you need answered, we can build a router on your model pool and your evidence.

Botscanner
A service of AutoBench
Botscanner is how you use that evaluation idea yourself. Ask one question of several language models at once, then let other models rank the answers so you can compare them on your own case.
Open Botscanner →botscanner.ai is the same service.
