A real answer from our test runs

Claude Haiku 5.5

Write an email to Tom declining his invitation to a vendor demo on Wednesday at 11:00, because you're presenting to the board then. Offer Thursday at 10:00 or Friday at 14:00 instead. Polite and brief: at most 120 words.

Subject: Re: Vendor Demo on Wednesday

Hi Tom,

Thank you for the invitation to the vendor demo on Wednesday at 11:00. Unfortunately, I'm presenting to the board at that time, so I won't be able to attend.

Would Thursday at 10:00 or Friday at 14:00 work for you instead? I'd be glad to reschedule.

Thanks for understanding, and I look forward to hearing from you.

Best regards,
[Your Name]
