Both are top-tier — but they have different strengths. Claude preserves tone and idiom; ChatGPT has broader specialized vocab. On Mac, the practical answer is: install Lazie and use both.

Mac-specific recommendation
Don't pick one and commit. Install Lazie, configure both Claude and OpenAI API keys. Per translation, hit the model switcher and re-translate through the other engine — pick the better baseline.
This A/B comparison costs 2-3 seconds and helps you build intuition for which model fits which content type in your specific workflow.
Cost on Mac
- Claude Sonnet — ~$3 per million input tokens. Typical Mac use: $1-5/month.
- GPT-4o — ~$2.5 per million input tokens. Typical Mac use: $1-10/month.
Costs are negligible for most users. Don't optimize early — start with both APIs configured in Lazie and switch freely.
