Comparison · Updated October 2026
PolyCog vs OpenRouter — side by side, fused, or debated
Both put many AI models behind one sign-in. OpenRouter is the widest catalog there is: 500+ models on one key, a chatroom that shows them side by side, and a Fusion beta that merges their answers. PolyCog is narrower on purpose: a handful of frontier models that read each other, argue, and write one answer. Its Wildcard seat runs on an OpenRouter key.
One prompt, two ways to get one answer from several models: OpenRouter Fusion has a panel answer separately, an analyst compare the drafts and a synthesizer write one result; PolyCog runs the models in parallel, scans for disagreements, has them debate, and synthesizes one answer.
The short version
OpenRouter is the widest door to AI models: one account and one balance for 500+ models from 80+ providers, at the providers’ own prices plus a 5.5% fee when you buy credits. Its chatroom sends one message to several models and shows the answers side by side, and Fusion (in beta) has a panel answer, an analyst compare the drafts and a synthesizer write one result. In neither do the models answer each other. PolyCog does that: a difference scan, debate rounds where each model reads the others, a verify pass that shows each claim’s source, then one synthesis by the flagship you pick, with sessions saved to your account on every device. The two aren’t really rivals: PolyCog’s Wildcard seat runs on your own OpenRouter key. If you build with AI or want the long tail of models, start with OpenRouter. If you want a question argued out, that’s us.
Who pays for what
OpenRouter adds no markup to the AI; it charges when you buy credits. PolyCog’s main seats skip the middle step.
OpenRouter
Prepaid credits · providers’ own prices · no subscription
You→ OpenRouter credits→ AI providers
OpenRouter passes on each provider’s own price with no markup and adds its fee when you buy credits. One balance pays for every model it lists.
PolyCog
BYOK · free tier, $10/mo or $250 once, for the interface only
You→ AI providers, directly
The main seats bill straight to your OpenAI, Anthropic, Google, DeepSeek and xAI accounts at list price. The Wildcard seat runs on your OpenRouter key, so those calls go through OpenRouter as above.

Your OpenRouter key works here too
PolyCog’s sixth seat, the Wildcard, runs on OpenRouter.
What the Wildcard opens
Qwen, Kimi, GLM, Mistral, Meta’s Llama and Muse, MiniMax, Venice and Nous, through one OpenRouter key you paste once.
Billed by OpenRouter
Those calls come out of your OpenRouter credits at its prices and show on its Activity page, exactly as in its own chatroom.
Your data setting, plus ours
PolyCog asks OpenRouter for hosts that don’t collect data, on top of the privacy settings in your OpenRouter account.
The other five seats use each provider’s own key, with no middle layer. How to get an OpenRouter API key →
Where your chats live
A chat you keep on one device is private to it. It also stays there.
Neither is a flaw: OpenRouter’s chatroom is a playground, and keeping conversations local is a sensible default for one. PolyCog keeps sessions in your account because a debate is something you come back to.
Where OpenRouter beats us
A comparison you can trust has to cut both ways, and OpenRouter is the best at what it does.
500+ models in one place
From the frontier labs to small open-weight models, all on one key and one balance, with new models often listed the day they launch. PolyCog covers 6 providers and 13 AI labs, on purpose.
Free models
OpenRouter’s free plan runs 25+ free models, 50 requests a day, or 1,000 a day once you’ve bought $10 of credits. PolyCog’s sample mode is three prompts a day; past that you bring paid keys.
One key, one bill
One balance pays for every model, with no account at each lab. PolyCog’s main seats each need that lab’s own key (our key guides walk through every one).
An API for developers
One OpenAI-compatible API for every model, routing and fallbacks between hosts, plus Ori’s command-line tools. PolyCog is an app, with no public API.
Where PolyCog wins
Models that answer each other
In OpenRouter’s chatroom the answers sit side by side, and in Fusion an analyst compares drafts the panel wrote alone. In PolyCog each model reads the others and replies, round after round, before anything is synthesized.
Claims checked, with the exact words
A verify pass looks up each factual claim and shows you the source and the sentence it found, before the synthesis is written. OpenRouter’s models can search the web; its docs don’t describe a claim-by-claim check you can read.
Your chats on every device
Sessions save to your account (20 on Free, 500 on Pro), so a debate started on the laptop opens on the phone. OpenRouter’s chatroom keeps conversations on the device you used, with export and import.
Your provider keys, no top-up fee
The main seats bill straight to your OpenAI, Anthropic, Google, DeepSeek and xAI accounts at list price, with nothing added. On OpenRouter every credit purchase carries its fee. (PolyCog’s own price is separate: free, or $10 a month.)
Common questions
Is OpenRouter cheaper than PolyCog?
For the AI itself they’re close: OpenRouter passes on the providers’ own prices and adds a 5.5% fee when you buy credits; PolyCog’s main seats bill straight to your provider keys at list price. What differs is the app and the number of calls. OpenRouter’s chatroom costs nothing; PolyCog is free, $10 a month or $250 once, and a PolyCog debate makes more calls than a single answer, which the estimate shows before each run. Fusion makes several calls too: OpenRouter puts a three-model panel at roughly four to five times the cost of one answer.
Can OpenRouter send one prompt to several models?
Yes. In its chatroom you pick one or more models, send one message, and read the answers side by side or as a list. The models don’t see each other’s answers there; Fusion is the step that compares them.
What is OpenRouter Fusion, and how is it different from a PolyCog debate?
Fusion (in beta) sends your prompt to a panel of up to eight models in parallel, each able to search the web. An analyst then lists where they agree, where they contradict each other and what they missed, and a model writes one answer from that analysis. It runs in OpenRouter’s Fusion lab, as a chatroom tool and through its API. The panel never answers each other. In PolyCog a difference scan flags the splits, the models read each other and reply in debate rounds, a verify pass checks the claims, and a flagship you pick writes the synthesis.
Can I use my OpenRouter key in PolyCog?
Yes, for the Wildcard seat: paste it once and the seat opens Qwen, Kimi, GLM, Mistral, Meta’s Llama and Muse, MiniMax, Venice and Nous. Those calls are billed to your OpenRouter credits as usual, and PolyCog asks OpenRouter to skip hosts that keep your data. The other seats use each provider’s own key. Our OpenRouter key guide walks through it.
Where are my chats stored?
OpenRouter’s FAQ says chatroom conversations are stored on your device and don’t sync between devices; you can export and import them. PolyCog saves sessions to your account, 20 on Free and 500 on Pro, so they open anywhere you sign in.
OpenRouter or PolyCog: which should I use?
OpenRouter if you build with AI, want one key for hundreds of models, or want the free models. PolyCog if you want a question argued out by several frontier models and one answer that names what they still disagree on. Plenty of people use both, and PolyCog’s Wildcard seat runs on OpenRouter.
