How we compare

Three categories sit nearby. Only Modeljury delivers the verdict.

Everyone else is a tool for engineers that lives inside your stack, or a leaderboard that never saw your task. We tell you the answer — and watch it.

Model routers & gateways

NotDiamond · Martian · Unify · Requesty · LiteLLM

Pick a model per request, in real time — sitting inside your API path.

✕Adds latency & lock-in; routes on generic benchmarks, not your data — and independent tests show they often pick the expensive model.

Eval & experimentation

Braintrust · Promptfoo · LangSmith · Langfuse · Vellum

Test models on your data — but you build the eval yourself.

✕Developer tooling (YAML, code, SQL). Hands you scores and dashboards, not a decision — and leans on a model to judge.

Leaderboards & pricing

Artificial Analysis · LMSYS Arena · llm-stats

Rank models on generic tasks by cost, quality and speed.

✕Not your task, and not a decision you can act on. The cheapest model per token isn’t the cheapest per task.
The verdict

Modeljury — the answer you own

Describe the job in plain English. We build the test on your data, run a real bake-off, and name the cheapest model that clears a confidence-backed bar — then alert you when a cheaper one qualifies.

1A decision, not a dashboard or a proxy. One model, run by you — nothing sits in your request path.
2Graded on your own data. Your real examples decide it — not a generic leaderboard.
3Plain English in, no eval to write. Built for the operator who can’t write a test harness.
4A confidence-backed verdict. A range, not a lucky score — and honest about ties.
5Stakes-first, cost-first, watched. Cloud + self-hosted compared; alerts when cheaper clears the bar.
6No model judging models. A model helps write the test; your data decides the verdict.
Positioning

Routers and eval tools are for engineers and live inside your stack. Modeljury is for the person who just wants to know — in plain English, proven on their own data — the cheapest model that’s good enough, and to be told when that answer changes.

Players listed are illustrative of each category, not exhaustive.
