Outputs

Claude Opus 4.7 8/10 
Hello, I wanted to follow up regarding the report I sent over last week. Have you had an opportunity to review it? I would appreciate your feedback as soon as possible so that I can complete my portion of the work. Please let me know at your earliest convenience.
Judge notes: Solid professional rewrite that preserves meaning and removes all casual language, but splitting into multiple short sentences slightly expands the original length and the closing phrase "at your earliest convenience" is a minor cliché that could be tightened.
Claude Haiku 4.5 8/10 
I wanted to follow up regarding the report I submitted last week. I would appreciate your feedback at your earliest convenience, as I need it to complete my portion of the project.
Judge notes: Solid and production-ready, but "at your earliest convenience" is a mild cliché and the urgency of the original "ASAP" is slightly softened without replacement.
GPT-5.4 8/10 
I wanted to follow up and see whether you have had a chance to review the report I sent last week. I would appreciate receiving it back as soon as possible so I can complete my portion.
Judge notes: The rewrite is clean and professional, but dropping the closing call-to-action ("let me know") slightly reduces the completeness of the original message's intent.
Gemini 2.5 Pro 7/10 
I am writing to follow up on the report I sent last week. Your feedback is required for me to complete my portion of the work.
Judge notes: The rewrite is clean and professional but loses the polite urgency of "ASAP" and drops any sense of a call to action (e.g., a requested timeline or prompt reply), making it slightly weaker than the original's intent.
Grok 4.1 Fast Reasoning 8/10 
I am following up to determine if you have reviewed the report I sent last week. I need it returned as soon as possible to complete my portion. Please advise.
Judge notes: Solid and professional, but "Please advise" is a slightly stiff closer that could be replaced with something warmer yet still formal, like "I would appreciate your feedback at your earliest convenience."
