3Free account limits, in plain words

Pay-as-you-go, low prices; add credit first. Here’s what happens if you hit a limit, and what to do.

When you’ve used your allowance, Nuxa says:

DeepSeek is limiting requests for now. Wait a minute and try again, or choose another AI.

When the account has no credit, Nuxa says:

DeepSeek says your account has no credit yet. Add credit or a payment method on the DeepSeek Platform website, then click Test again, or choose a free option.

Wait

Wait a little

Most limits clear within a minute; free daily limits reset overnight. Then click Test again in Nuxa.

Upgrade

Add credit or upgrade

Add credit or a payment method on the DeepSeek Platform.

Switch

Free choices: Google Gemini, Ollama on your Mac, or ChatGPT. You can switch any time.

4Troubleshooting

Tap a problem to see the fix.

Step 1 Sign in to the DeepSeek Platform

I use the DeepSeek chat app; isn't that enough?
The chat app doesn't include API access. The key comes from the DeepSeek Platform.
The page didn't open
Open your web browser yourself and go to platform.deepseek.com/api_keys.
The page won't load
Check that you're online. A VPN or work network may block it; try another network.

Step 2 Click “Create new API key”

It asks me to top up
The API needs a small balance before it answers. Top up, then come back.
I don't see API keys
Look in the menu on the left of the Platform page.

Step 3 Click “Copy”

I closed it before copying
Most services show a key only once. Create another key and copy that one.
I can't find a copy button
Select the whole key and press ⌘C.

Step 4 Nuxa finds your key

Nuxa says it looks like a different kind of key
You may have copied a key from another service. Go back to the key page and copy the key again with its Copy button.
Nuxa says the key looks incomplete
Part of it was missed. Use the Copy button next to the key rather than selecting it by hand.
macOS asks whether Nuxa may paste
Click Allow Paste. Nuxa only looks at the clipboard when you click Paste key, or when you come back to Nuxa during this step.
Paste key does nothing
Copy the key again, then click Paste key. Or click into the box under the button and press ⌘V.

Step 5 Checking your key…

DeepSeek didn't accept the key
Copy the whole key again with its Copy button and paste it. If you deleted the key on the website, create a new one.
It says the limit was reached
DeepSeek is limiting requests for now. Wait a minute and try again, or choose another AI.
It says there's no credit
DeepSeek says your account has no credit yet. Add credit or a payment method on the DeepSeek Platform website, then click Test again, or choose a free option.
It says Nuxa couldn't reach DeepSeek
Check that you're online. A VPN, a work firewall or a content filter can block it; try switching the VPN off.

Any step Something else

I'm offline
Setting up needs the internet (except a model that's already on your Mac). Connect, then try the step again.
I use a VPN or a work network
VPNs and work firewalls sometimes block AI services. Try with the VPN off, or on another network.
macOS asks for permission
Nuxa may ask to paste from the clipboard or to open a web page. Click Allow; nothing happens without your click.
Nothing seems to happen
Click Check again, or go Back one step and try again. If you're stuck, click Get help — it tells us which step you're on.
