Select the translation source and target language in the language/model selector.

Step 1: Create account and balance

Go to OpenRouter, create an account, and add a small balance. For testing, even a small amount is enough.

Step 2: Generate API key

Create a new API key in your OpenRouter dashboard and keep it private.

Step 3: Add key in Thaluna

Open Settings → Ollama/Cloud, paste the key, choose a model, and save.

Step 4: Enable OpenRouter in Languages

Open the translation model selector, switch to OpenRouter, choose the target language, and confirm with OK.

Which OpenRouter model should I choose?

Thaluna includes presets for Gemini 2.5 Flash Lite, GPT-5.6 Luna with reasoning disabled, GPT-4.1 nano, GPT-4o mini, and other models. For current quality, speed, and price guidance, read the Translation Quality Guide.

If cloud mode is not working

  • Regenerate the API key and paste it again carefully
  • Make sure the key saved in %localappdata%\Thaluna\secrets\openrouter_api_key.json matches your current key
  • Check that your OpenRouter account has balance available
  • Try a different model
  • Temporarily test another network or phone hotspot if VPN, proxy, firewall, or antivirus web protection may be interfering
