Anthropic API vs Google Gemini API
Anthropic API never trains on your inputs at any tier; the Gemini API's free tier may, while its paid tier does not. For confidential data the distinction matters from the first request.
Key differences
- Free-tier data use: Anthropic has no training-on-input at any tier; Gemini's free tier may use prompts for product improvement.
- Enterprise path: Anthropic offers Zero Data Retention on request; Google offers Vertex AI for stricter isolation.
- Both assign output ownership to the customer and permit commercial use.
- Model strengths differ — evaluate on your own reasoning, long-context, and multimodal workloads.
