Claude Haiku 5.5
Passed: Graded 4.7 of 5 on average (lowest 4).
Subject: Your rain jacket order Hi there, I'm sorry your rain jacket hasn't arrived. Standard delivery normally takes 3 to 5 business days, and yours is now 9 business days out, so it's well past due. Because your order is more than 7 business days late, you're eligible for free express shipping on your next order. Just mention this order when you place it, and we'll apply the upgrade. I'm also sorry for the wait. I don't have tracking details in this message, so if you can share your order number, I'll look into where it is and what we can do next. Thanks for your patience.

GLM 5.3 Flash
Failed: Graded 3.7 of 5 on average (lowest 3).
Dear customer, Thank you for reaching out, and I'm sorry your rain jacket hasn't arrived yet. That's certainly not the experience we want for you. Standard delivery normally takes 3–5 business days, and since your order is now 9 business days overdue, it has clearly been delayed. I apologize for the inconvenience. Because your order is more than 7 business days late, I'd be happy to add free express shipping to your next order as a gesture of apology. Just reply to this message or mention it when you place your next order, and we'll apply it. Please also keep an eye out for the package — if it hasn't arrived within the next few business days, contact us and we'll investigate with the carrier or arrange a replacement or refund. Thank you for your patience. Sam, Northwind support

Claude Haiku 5.5 and GLM 5.3 Flash on every plan
Whether the one-time free trial reaches each model, then each paid plan's messages on it.
| Plan | Price | Claude Haiku 5.5 | GLM 5.3 Flash |
|---|---|---|---|
| Free | $0 | In the one-time trial of 5 messages | In the one-time trial of 5 messages |
| Pro | $20 a month | 60 a day | 60 a day |
| Max | $50 a month | 120 a day | 120 a day |
| Ultra | $100 a month | 200 a day | 200 a day |
| Studio | $200 a month | 200 a day | 200 a day |
Prices don't include tax, which is added where it applies and shown before you pay. A paid plan's month is one allowance shared by every model, so each monthly count is the most you get if all of it goes to that model. It renews each billing period; everyday models refill daily at 00:00 UTC. Long chats count more per reply. How pricing works.
Every limit is published. Paid plans also have a monthly fair-use limit on AI cost: Pro $7.50, Max $20, Ultra $42, Studio $85. Using every message on your plan at typical sizes stays under it; very large messages and heavy research use it faster. Every limit, explained.
