OpenAI Translator is a popular open-source tool for text translation on browsers and desktops. By pairing it with DeepSeek V3, you get a high-quality, cost-effective bilingual reading assistant.
Configuration Steps
We use the Custom Model or OpenAI Compatible method.
1. Browser Extension / Desktop App
- Open the Settings page.
- Go to the AI Provider tab and select OpenAI.
- Toggle on "Custom API URL".
- Fill in the details:
- API URL:
https://api.deepseek.com(Try adding/v1if it fails, i.e.,https://api.deepseek.com/v1) - API Key: Your DeepSeek Key (
sk-xxxx) - Model: Manually type
deepseek-chat
- API URL:
- Save and Test.
Note: Newer versions might have a built-in "DeepSeek" provider option. If available, use that instead. If not, the "Custom OpenAI" method above always works.
Why DeepSeek?
- Better Translation: DeepSeek understands context and nuance better than standard machine perception models, often rivaling GPT-4.
- Versatility: It can explain code, summarize paragraphs, or rewrite text, not just translate.
FAQ
Q: Infinite loading spinner?
A: Check the API URL. Some versions require the URL to end with /v1, while others strictly need the base domain. Try toggling between https://api.deepseek.com and https://api.deepseek.com/v1.
Q: "Model not found"?
A: Ensure you typed deepseek-chat exactly. Do not use v3 or other aliases.
