How to fill this in FgoGotran
- Never share your API key, and do not post screenshots showing the full key.
- After a successful test, tap “Apply API settings”, otherwise the new settings will not take effect.
- Prefer the full model name shown in the provider's docs or console.
- You must select the Claude interface type in the app.
- The Claude API format is not OpenAI Chat Completions; do not put it in the custom OpenAI-compatible slot.
- For low-cost everyday translation, test Haiku first.
