Immersive Translation

Immersive Translation supports custom OpenAI-compatible interfaces, using large models to achieve results far better than traditional machine translation.

Configuration Steps

  1. Open the extension’s Settings → Translation Services, select OpenAI, and enter its settings;
  2. Switch to Custom API Key mode, and fill in:
    • API Key: your sk- token
    • Custom API Endpoint: https://api.4allapi.com/v1/chat/completions
    • Model: enter a custom value, such as deepseek-v4 (high cost performance) or gpt-5.6
  3. After saving, enable translation on the webpage.

Recommendations

  • Web page batch translation involves a large request volume, so low-cost models are recommended (deepseek-v4, omni-flash), whose quality is already significantly better than traditional machine translation;
  • Lowering the maximum requests per second setting a bit (for example, 5–10) can help avoid triggering 429;
  • For long-document translation such as PDFs/subtitles, it is recommended to create a separate token for translation to make usage easier to monitor.
