What are the differences between generative AI engines GPT-4.1 and Claude?

【Security】 

No generative AI engines reuses the data input by users for secondary purposes.

Here is the information about the data storage and processing serverss.

• GPT-4.1 and GPT-4.1 mini:  The data is not stored anywhere (zero retention policy applied), but the data can be processed outside Japan (US)
• Claude: The data is not stored anywhere, but the data can be processed outside Japan (US Virginia and US Oregon). 
• Gemini 2.0 Flash: The data is not stored anywhere, but the data can be processed outside Japan (US). 

【Translation processing speed】 

•  GPT-4.1 mini is a lightweigth model with fast processing speed and reduced latency
• Gemini 2.0 Flash has fast processing speed, but has limit on number of tokens to be handled at a time
• GPT-4.1 has normal processing speed, but still a bit slower than conventional machine translation engines
• Claude has the slowest processing speed
