Flux Router models
Use Flux Router's four tiers and 70+ models on Fuigo, Claude Code, Codex, Qwen and Hermes with one key.
Flux Router is an optional, paid service that gives you 70+ models through one key. In Murage it shows up as four model choices at the top of a bot's model list, plus specific models you can pin. It's not an engine by itself: a bot still runs on an engine, and the engine sends its requests to Flux Router.
Flux Router runs on credits. Model requests use your Flux Router balance.
The four tiers
The model list always starts with these, in this order:
- Flux Auto: Flux Router picks a model for each turn. What a turn costs depends on which model runs.
- Flux Fast
- Flux Standard
- Flux Reasoning
Below your favorites and the engine's own models, a Flux pinned models group lists specific models routed through Flux Router, if you want one model every time.
Which engines can use Flux Router
- Fuigo: yes. Flux Router is all Fuigo needs to think.
- Claude Code: yes.
- Codex: yes.
- Qwen: yes. The key is passed for the turn only and never written to Qwen's settings.
- Hermes: yes. Hermes gets a private, temporary settings folder for Flux turns.
- OpenCode: only once Flux Router has been added as a provider in OpenCode's own settings. Murage never writes that during a turn.
- OpenAI-compatible: Flux Router's models can be picked for plain chat.
- Grok Build, Cursor, Droid: no. They only talk to their own services.
- Kimi, pi, Google Antigravity: no.
When a bot is on an engine that can't use Flux Router, the tiers aren't offered in its list.
Set it up
- Open Settings → Models.
- In the Flux Router card, paste your key and choose Connect. Choose Sign up for Flux Router first if you don't have a key.
- Choose Test connection to check that the model list loads. This doesn't send a model request.
- Open a bot, go to Bot settings → Model, and pick Flux Auto or another tier.
The key is kept in your computer's secure storage. No bot ever sees it.
What else the same key covers
- Live web search with sources.
- Voice for calls and voice notes, and transcription.
- Pictures made in the chat.
- Connected apps, unless you use your own connected-apps key.

Known limits
- It's paid. A bot on a Flux tier stops working when your balance runs out or a spending limit is reached.
- A tier is a routing choice, not a fixed model. If you need the same model every time, pick a Flux pinned model.
- If you have two Flux Router connections, each connection's tiers are listed separately, because they may bill different accounts.
Troubleshooting
"The provider reported that its available credit balance was exhausted." Add credits to Flux Router. If you already have, retry once the new balance shows. You can also pick another engine or model.
"The account reached the spending limit set for it this month" The limit rises as the account builds payment history, so adding credit won't lift it straight away. Ask Flux Router to raise it, or pick another engine.
"Provider payment or account access required" Flux Router returned a payment error. Check your balance and access to that model.
"The provider rejected the credentials used for this request." Reconnect Flux Router in Settings → Models with a working key.
The tiers don't appear for a bot The bot's engine can't use Flux Router. Switch it to Fuigo, Claude Code, Codex, Qwen or Hermes in Bot settings → Model.
