Claude Sonnet 5 on every plan
What Claude Sonnet 5 costs in llmwise is a count, not a token bill: up to 125 a month on Pro, and it isn't in the free trial.
| Plan | Price | Claude Sonnet 5 messages | Each, if all go to Claude Sonnet 5 |
|---|---|---|---|
| Free | $0 | Not in the trial | — |
| Plus | $10 a month | Up to 62 a month | $0.16 |
| Pro | $20 a month | Up to 125 a month | $0.16 |
| Max | $50 a month | Up to 400 a month | $0.13 |
| Ultra | $100 a month | Up to 900 a month | $0.11 |
| Studio | $200 a month | Up to 2,000 a month | $0.10 |
Prices don't include tax, which is added where it applies and shown before you pay. A paid plan's month is one allowance every model shares, so each Claude Sonnet 5 count is the most you get if all of it goes to Claude Sonnet 5, and "each" is the plan's price divided by that count. How pricing works.
Every limit is published. Paid plans also have a monthly fair-use limit on AI cost: Plus $3.75, 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.
Claude Sonnet 5 usage limits, explained
Every limit on Claude Sonnet 5 in llmwise is published. Here's each one, in Claude Sonnet 5 messages.
Claude Sonnet 5 draws on the monthly allowance every model shares: 125 Claude Sonnet 5 messages on Pro if nothing else uses it. Each message on a smaller model leaves fewer Claude Sonnet 5 messages, each Claude Sonnet 5 message leaves fewer for them, and unused Claude Sonnet 5 messages don't carry over when the billing period renews.
Long Claude Sonnet 5 chats count more, because each Claude Sonnet 5 reply resends the whole conversation. Past 64k tokens a Claude Sonnet 5 reply counts as 2 messages, so Pro's 125 Claude Sonnet 5 messages become up to 62 such replies; past 128k it counts as 4 (up to 31 Claude Sonnet 5 replies); past 200k the Claude Sonnet 5 chat is full.
Claude Sonnet 5's native context window is 1M tokens; llmwise stops a Claude Sonnet 5 chat at 200k tokens, so a Claude Sonnet 5 chat uses at most 200k of its 1M tokens.
A Claude Sonnet 5 reply can run to 8,000 tokens on Plus and Pro and 16,000 on Max, Ultra, and Studio, at the same Claude Sonnet 5 price however long it runs.
On a paid plan each web search or link read in a Claude Sonnet 5 reply counts as 1 more Claude Sonnet 5 message.
A $10 top-up adds up to 100 more Claude Sonnet 5 messages, valid 12 months, spent once the plan's own Claude Sonnet 5 count is gone.
Claude Sonnet 5 replies share every plan's soft cap of 100 replies an hour with the other models.

How Claude Sonnet 5 began its reply to our first writing prompt, “Write a LinkedIn post of 100 to 150 words announcing that our small bakery, Crumb & Co., opens a second shop in Leeds on 14 November. Mention the free coffee…”:

This has been months of planning, a lot of taste-testing, and more excitement than we know what to do with. We can't wait to welcome you in, share some fresh bakes, and start building new memories together. See you there — first coffee's on the…
