Hi!
Thank you so much for answering! (Maybe it would be better to make a discord so that I can videos to you instead but that's just me lol)
As for my settings, since I'm on pc and tried it, it wouldn't let me select GPU but it says it wouldn't let me in a way
The screenshot I showed above was a vid on bilibili and I'm still kinda unsure how to change the settings when it comes to my screen I'm gonna be honest
As for the Opencloud, ill see but I dont it will solve it 100% though
Hey! Thanks for the screenshots — that helps a lot
The "Ollama server not found" message is completely normal if you're not using Ollama. You can safely ignore it — OpenRouter does not require Ollama at all.
Since your system doesn't allow GPU selection, it most likely means you don't have a CUDA-capable NVIDIA GPU. In that case everything runs on CPU:
- OCR → CPU
- Local translation models → CPU
That's why it can struggle to keep up in visual novels or videos — your CPU is handling both tasks at the same time.
Using OpenRouter will help because your CPU will only handle OCR, while translation runs in the cloud instead.
Here's how to set it up:
1. Go to https://openrouter.ai and create an account.
2. Add a small balance (even $5 lasts a very long time).
3. Generate an API key.
4. In Thaluna → Settings → Ollama/Cloud section, paste your API key in the OpenRouter field.
⚠️ Important: Do NOT share your API key publicly or paste it in chat. Keep it private.
5. Leave the default model (Gemini 2.5 Flash Lite).
6. Go to Languages → select OpenRouter as the translation provider.
7. Choose your target language and click OK.
Also make sure the video or game is not running in true fullscreen mode — if it takes over your whole screen, try switching to Windowed or Borderless Windowed in the display settings.
Try that and let me know how it goes
Hello! Of course its a slow process and again thank you for taking your time with me!
I am not sure if I did it right but I got the API key and copy and paste on the thing but I didnt see the language thing unfortunately so I'm not where it is but I'm wondering if I did do it right though (You can ignore the Ollama server thing again, since I just realized I didn't have to do it again)
Hey! You're very close — the API key part looks correct 👍
I made a quick visual guide for you (see the screenshots). Just follow these steps:
1️⃣ Click the Language button at the top of Thaluna.
2️⃣ In the window that opens, switch to the OpenRouter (Cloud) tab.
3️⃣ Select OpenRouter: Cloud Translation.
4️⃣ Choose your Target Language (for example English).
5️⃣ Click OK.
After that Thaluna will start translating using OpenRouter.
One small recommendation:
I noticed your API key currently has no spending limit (unlimited).
OpenRouter is prepaid, so it will only use your balance, but it's still a good idea to set a small limit (for example $5) on the key.
This just prevents accidental higher usage if something runs in the background.
This error means OpenRouter rejected authentication (401: Missing Authentication header).
Usually this happens when the OpenRouter API key is missing or incorrect in the app settings.
Please try the following:
1. Go to Settings → Ollama / Cloud.
2. Paste your OpenRouter API key again (make sure there are no spaces before or after the key).
3. Save the settings and restart Thaluna.
4. If it still doesn't work, generate a new API key on OpenRouter and paste it again.
If you are using a VPN, proxy, or firewall, try disabling it temporarily and test again.
When OpenRouter authentication fails, Thaluna automatically switches to a local fallback translation model.
If you're still unsure whether the API key was saved correctly, you can also check it manually.
Sometimes when copying a key (especially after regenerating it or changing limits), a space or extra character can accidentally be included. That can cause the authentication error.
Thaluna stores the OpenRouter key in the following file:
C:\Users\YourUserName\AppData\Local\Thaluna\secrets\openrouter_api_key.json
The easiest way to open it:
Press Win + R on your keyboard.
Type:
%localappdata%\Thaluna\secrets
Press Enter.
Open the file openrouter_api_key.json with Notepad and check if your API key is there.
You can also paste your key into this file if needed.
⚠️ Make sure Thaluna is completely closed before editing the file, otherwise the change may not save correctly.
This method can help confirm that the correct key is stored without any extra spaces or characters.
Also remember to keep your API key private and never share it publicly.
Hello
Please check the following:
Generate a new API key on OpenRouter.
In Thaluna settings, delete the old key completely and paste the new one.
Make sure you paste the entire API key exactly as OpenRouter gives it, not just part of it.
Click the button next to the API field to reveal the key and verify it looks correct.
Click Save / OK, then fully restart Thaluna.
If the problem still happens, please check the stored configuration manually:
Press Win + R
Type:
%localappdata%\Thaluna\secrets
Open openrouter_api_key.json
Verify that the API key stored there matches your current OpenRouter key exactly.
This error usually means one of the following:
the API key is missing, incorrect, or saved incorrectly
the app is still using an old/invalid key
If the steps above still don't fix the issue, please try one quick test:
Temporarily switch to a different internet connection (for example your phone hotspot) and test Thaluna again.
Sometimes a VPN, proxy, firewall, or antivirus web protection can interfere with API authorization requests.
Using a different network for a quick test can help confirm if the issue is network-related.
