✗ Some paragraphs are slightly long; high information density may affect fast reading.

✓ Terminology such as "air-source heat pump" is accurately translated.

✗ Insufficient fluency; "suddenly exploded in popularity" has an awkward translation tone.

gpt-o3

✓ The policy section is precise, with consistent terminology for "Inflation Reduction Act".

✗ Some sentences are slightly verbose; e.g., the description of heating/cooling efficiency could be more concise.

Conclusion: Version A is the best overall, balancing accuracy and fluency; Version C comes second; Version B has minor issues with fluency and paraphrasing.

claude-sonnet-4.6

✓ Terminology is accurate and consistent, such as "face-swap" used throughout, faithfully corresponding to the original text.

✗ Some long sentences are slightly cumbersome; e.g., the end of the first paragraph "the majority of victims are unsuspecting women and girls" could be more concise.

deepseek-v4-pro

✓ The title translation is direct and clear, "San Francisco Demands Apple and Google Remove AI 'Undressing' Apps" effectively conveys the original message.

✗ Fluency is slightly lacking; some expressions like "false nude images" feel a bit stiff compared to other versions.

gpt-o3

✓ Best overall readability, with smooth paragraph transitions; e.g., the translation of "face-swapping" is natural and logically clear.

✗ Terminology consistency is slightly weaker; e.g., "face-swapping" and "face-swap apps" are used interchangeably, not fully unified.

Conclusion: Version C (gpt-o3) is the best overall, outstanding in fluency and readability; Version A has strong accuracy; Version B is slightly weaker than the other two.

passthrough

✓ Accurately reproduces the original time "July 15 and 16", and faithfully describes the cooperation details of Jensen Huang's trip with Japanese industry, without adding fabricated content.

✗ The text is abruptly cut off at the end, with "The country doesn't want to run i" resulting in incomplete information and affecting overall readability.

deepseek-v4-pro

✓ Paragraph transitions are relatively smooth; the subtitle "SoftBank's AI Network Ambition" is used clearly.

✗ Seriously deviates from the original text; "From June 17 to July 20" does not match the original July 15-16 time, and adds a large amount of specific transaction details about SoftBank, Sony, and Toyota not mentioned in the original, constituting excessive addition.

gpt-o3

✓ The language is natural; the title "Jensen Huang's Japan Trip" is concise, and "unprecedented opportunities" is quite idiomatic.

✗ Similar to the deepseek version, it fabricates the time "June 17 to July 20" and numerous collaboration details with SoftBank not present in the original, compromising accuracy.

Conclusion: Version A has the highest accuracy; Versions B and C both have serious factual errors and content additions, not recommended for use.
