Other plans as of September 25, 2026; they can change without notice. Want the most messages from one AI? Its own plan is better value. Want the right AI for each question, with the count up front? That's llmwise.

Monthly list prices as of September 2026: ChatGPT Plus, Claude Pro, Google AI Pro.
Claude Pro usage limits
Anthropic's plans, in one sentence each, with the pages that say so.
Anthropic publishes no fixed message count for Claude Pro: usage is measured in 5-hour sessions, with a weekly cap on top.
Checked : Anthropic Help Center (Pro plan usage).
Claude Pro doesn't include Claude Fable 5.1 in its usage limits: since July 20, 2026, Pro subscribers pay for Fable 5 and Fable 5.1 separately, from the first message.
Checked : Anthropic Help Center (Fable on your plan) and Claude pricing.
Claude Max includes Fable 5 and Fable 5.1, but they can use at most 50% of Max's weekly limits.
Checked : Anthropic Help Center (Fable on your plan) and Claude pricing.
In practice you learn your limit by reaching it, then wait for the session, or the week, to reset. Fable is the exception on Pro: it isn't in the limits at all, and costs extra from the first message. More on that in Is Claude Fable 5.1 included in Claude Pro? Claude Pro against llmwise, plan by plan: Claude Pro vs llmwise.
ChatGPT Plus usage limits
OpenAI's limits for GPT-6 on Plus, with the pages that say so.
In Work and Codex, OpenAI estimates 5–45 local GPT-6 Astra messages every 5 hours on Plus, and says these aren't fixed limits and weekly limits may also apply.
Checked : OpenAI Help Center.
ChatGPT Plus offers GPT-6 Astra only in Work and Codex, not in ChatGPT's regular chat.
Checked : OpenAI Help Center.
GPT-6 Sol and GPT-6 Luna, which OpenAI launched on September 22, 2026, aren't yet available in ChatGPT's Chat mode.
A range rather than a number: how many Astra messages you get in a window depends on what you ask. More in Does ChatGPT Plus include GPT-6 Astra? The whole plan against llmwise: ChatGPT Plus vs llmwise.
Google AI Pro (Gemini) usage limits
Google's limits for Gemini on Google AI Pro, in Google's words.
Since May 17, 2026, Google AI Pro has used compute-based limits that, in Google's words, “factor in the complexity of your prompt, the features you use, and the length of your chat”, and Google publishes no message count for them.
Checked : Google Gemini Help (compute-based limits) and PCWorld.
So a long chat, a big file or a heavier feature uses more of the limit, and Google doesn't say how much more. The plan against llmwise: Google AI Pro vs llmwise.

Free is a one-time trial shared by the models marked. A paid plan's monthly counts come from one allowance, so each is the most you get if all of it goes to that model; the daily counts are separate. How pricing works has every rule.
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.
A count for every model, per plan, in the table above. The model picker shows what's left on each, and the message box shows it again before you send.
Everyday models (Claude Haiku 5.5, GPT-6 Luna, DeepSeek V4.1 Flash, and GLM 5.3 Flash) have their own daily count: 60 messages a day on Pro, refilled at 00:00 UTC.
A soft cap of 100 replies an hour, on every plan.
A reply can be up to 8,000 tokens on Pro and 16,000 on Max and up; at the limit it stops and offers Continue.
Long chats: once the conversation sent to the model passes 64k tokens, each reply counts as 2; past 128k, as 4; past 200k the chat is full. The message box says so before you send.
No 5-hour sessions and no weekly caps.
Each rule, and how we set the numbers, is on How pricing works, and the full list of limits is in Limits and reliability.
Where llmwise gives you less
Fewer messages on any one model than its maker's own plan is likely to give a heavy user of just that model. llmwise is one plan for every model, not the most of one.
Unused messages don't carry over to the next month.
On a paid plan, each web search counts as one more message of the model in use, and research reports and images have prices of their own.
The fair-use limit on each month's AI cost ($7.50 on Pro): at 100% of it, every message pauses until the plan renews or you buy a $10 top-up.

Usage limits: what people ask
How many messages do you get on Claude Pro?
Anthropic doesn't publish one, as of September 25, 2026: according to its Help Center, Pro's usage is measured in 5-hour sessions with a weekly cap on top. Any fixed number you see elsewhere is someone's estimate.
How many GPT-6 Astra messages do you get on ChatGPT Plus?
In Work and Codex, OpenAI estimates 5–45 local Astra messages every 5 hours on Plus (as of September 25, 2026). Astra isn't in ChatGPT's regular chat on Plus.
What are Google AI Pro's usage limits?
Since May 17, 2026, compute-based limits that depend on your prompt, the features you use and the length of your chat. Google publishes no message count for them (as of September 25, 2026).
Why can llmwise publish its limits?
Because every message has a fixed price in llmwise, a month's allowance divides into a count for each model, so there's a number to publish. How we set the numbers is on How pricing works.
Does llmwise have no limits at all?
No: it has limits, and publishes every one. The counts per model, 60 everyday messages a day on Pro, 100 replies an hour, long-chat rules and a monthly fair-use limit. It's predictable, not endless.
Limits you can read before you reach them
Every llmwise plan states its count per model. On Pro ($20): up to 62 a month on Claude Opus 5.5, up to 250 a month on Claude Haiku 4.5.
