Claude Opus 5.5 on every plan
What Claude Opus 5.5 costs in llmwise is a count, not a token bill: up to 62 a month on Pro, and it isn't in the free trial.
| Plan | Price | Claude Opus 5.5 messages | Each, if all go to Claude Opus 5.5 |
|---|---|---|---|
| Free | $0 | Not in the trial | — |
| Plus | $10 a month | Up to 31 a month | $0.32 |

| Max | $50 a month | Up to 200 a month | $0.25 |

| Studio | $200 a month | Up to 1,000 a month | $0.20 |
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 Opus 5.5 count is the most you get if all of it goes to Claude Opus 5.5, 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 Opus 5.5 usage limits, explained
Every limit on Claude Opus 5.5 in llmwise is published. Here's each one, in Claude Opus 5.5 messages.
Claude Opus 5.5 draws on the monthly allowance every model shares: 62 Claude Opus 5.5 messages on Pro if nothing else uses it. Each message on a smaller model leaves fewer Claude Opus 5.5 messages, each Claude Opus 5.5 message leaves fewer for them, and unused Claude Opus 5.5 messages don't carry over when the billing period renews.
Long Claude Opus 5.5 chats count more, because each Claude Opus 5.5 reply resends the whole conversation. Past 64k tokens a Claude Opus 5.5 reply counts as 2 messages, so Pro's 62 Claude Opus 5.5 messages become up to 31 such replies; past 128k it counts as 4 (up to 15 Claude Opus 5.5 replies); past 200k the Claude Opus 5.5 chat is full.
Claude Opus 5.5's native context window is 1M tokens; llmwise stops a Claude Opus 5.5 chat at 200k tokens, so a Claude Opus 5.5 chat uses at most 200k of its 1M tokens.
A Claude Opus 5.5 reply can run to 8,000 tokens on Plus and Pro and 16,000 on Max, Ultra, and Studio, at the same Claude Opus 5.5 price however long it runs.
On a paid plan each web search or link read in a Claude Opus 5.5 reply counts as 1 more Claude Opus 5.5 message.
A $10 top-up adds up to 50 more Claude Opus 5.5 messages, valid 12 months, spent once the plan's own Claude Opus 5.5 count is gone.
Claude Opus 5.5 replies share every plan's soft cap of 100 replies an hour with the other models.

Where your Claude Opus 5.5 messages go
A Claude Opus 5.5 message goes to Anthropic directly when llmwise can reach Anthropic, or through OpenRouter when it can't.
If Anthropic fails before a Claude Opus 5.5 reply starts (an overload, a server error, a dropped connection), llmwise resends the Claude Opus 5.5 request through OpenRouter, to endpoints that, according to OpenRouter, don't store prompts for their own use or train on them.
Anthropic's safety system can pass a Claude Opus 5.5 message to another Claude model. When it does, the reply names the model that answered and is charged that model's price, never more than Claude Opus 5.5's.
The Privacy Policy lists every company a Claude Opus 5.5 message can reach.

How Claude Opus 5.5 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…”:
Some news we've been keen to share: Crumb & Co. is opening a second shop in Leeds on 14 November. When we first opened our doors, we hoped a few people might come back for a second loaf. We never imagined the support we'd get from so many of you, week after week. Your custom, your kind words and your recommendations to friends are what made this possible. The new shop will have the same bread, pastries and cakes you know, baked fresh each morning by the same small team, with a few new faces joining us. To say thank you, coffee is on us all day on opening day. Pop in, say hello and have a look around. We can't wait to meet our new neighbours and to see familiar faces too. See you on the 14th.
