Author your own benchmarks

Questions, prompt, sampling, scorer — versioned and re-runnable.

Full transcripts & scoring

Every prompt, response, and score. See exactly why it passed or failed.

Head-to-head compare

Models side by side, question by question. Find where cheap holds up.

Any OpenAI-compatible endpoint

Point at a URL and key — local or hosted. Nothing to rewrite.

How it works

Three steps to a real answer.

No SDK, no data export. Connect, benchmark, decide.

01

Connect an endpoint

Add any OpenAI-compatible URL and key. Test it in one click.

02

Pick or author a benchmark

Run a published version, or write and version your own.

03

Run and compare

Benchmark one or many. Track pass rates and compare head-to-head.

Pricing

Priced to run more evals, not fewer.

Billed in credits — 1 completed run = 1 credit; an AI-generated question = 3.

FAQ

Questions, answered plainly.

Anything that speaks the OpenAI chat-completions API — llama.cpp, vLLM, Ollama, OpenRouter, OpenAI, and most hosted providers. You add a base URL and a key, and Rackor runs against it. No SDK or code changes.

Stop guessing which model to ship.
