Most AI apps hand you one model and hope it's the right one. Multi lets you ask a single model, compare a few side by side, convene a council of up to seven, or let Multi pick for you — all from the same prompt.

The unfair advantage
No single model wins at everything. Multi puts 300+ models from every major lab to work across four workflows, so you deploy the best AI for each task instead of forcing one to do it all. Using the right model for the right project is the advantage most people leave on the table.
Coding, research, long documents, raw speed — route each job to the model that's actually best at it.
Compare a few, or convene a council of up to seven, so high-stakes calls aren't left to one model's blind spots.
The catalog stays current and vendor-neutral. The newest frontier models show up automatically — no waiting.
From every major lab, via the live OpenRouter catalog
Write your task first, then choose how Multi runs it. Not sure which fits? Multi reads your prompt and suggests the right one.
No model names to learn. Describe the task and Multi weighs quality, speed, and cost — then routes to the right model and shows you exactly which one it chose, and why.
A clean, familiar chat with one model you pick — for everyday work where you already know the tool for the job.
The same prompt, answered independently by 2–4 models. See how they reason side by side, then keep the best.
Up to seven models answer independently — then a judge you choose cross-checks them and writes one clear verdict.
Flip on Free Mode and Multi uses only compatible zero-cost models — for chat, comparisons, councils, and automatic picks alike. It will never quietly fall back to a paid model to finish the job.
Chat with a single compatible zero-cost model.
Put up to four free models side by side.
A free council answers; a free judge synthesizes.
Let Multi choose an available free model for you.
Paid and mixed routing profiles are locked while Free Mode is on.
The free-model pool refreshes from the live OpenRouter catalog.
Comparisons, councils, and automatic picks all work free.
Several free models answer before a compatible free judge decides.
Multi tells you when free models are slower or unavailable.
Free models can be slower, less capable, or temporarily unavailable — Multi tells you plainly, and never charges to make up the difference.
Start anywhere and keep going. Multi carries your prompt and the answers you kept from one mode to the next — no copy-pasting between tools.
Turn on live search and page fetching for One Answer, Compare, or the whole council — with source links shown next to the responses that used them.
Every automatic pick comes with a plain route receipt, so you're never guessing what ran (where OpenRouter reports it).
Built for control & transparency
A protected admin control plane decides which models show up where, how each mode behaves, and publishes changes safely.
No subscription, no seats, no per-answer fees. You bring your own key, so model usage is billed straight to you at cost.
Same product everywhere — pricing adjusted for your region.
And you bring the key
The license buys the software. The models run on your own key — so what does that mean? You connect one OpenRouter API key and it unlocks every model in the catalog. Usage is billed by OpenRouter at their rates, straight to your account. Multi never adds a per-token fee on top.
Put 300+ models to work — the right one for every task, across four workflows.
