ChatGPT Plus's cells: OpenAI's own pages, checked September 26, 2026. Ours: llmwise's plans, where each monthly count is the most you get if all of the month's allowance goes to that model.
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.
Where ChatGPT Plus is better
More Astra for Codex work: OpenAI estimates up to 45 GPT-6 Astra messages every 5 hours in Work and Codex on Plus, which can add up to far more than llmwise Pro's 31 a month.
Codex and ChatGPT Work, OpenAI's own coding and agent tools, which llmwise doesn't have, and voice chats: llmwise has no voice mode.
More of one family (our reading): if GPT is all you use, Plus is built for it, while llmwise shares one allowance across 15 models.
Where llmwise is different
A published count on every model, shown before you send: on llmwise Pro ($20), up to 31 Claude Fable 5.1 messages a month, 62 on Claude Opus 5.5 or 125 on Claude Sonnet 5, from one shared allowance.
7 AI families in one chat, 15 models in all; switch models mid-chat and the next one sees the whole conversation.
No 5-hour sessions and no weekly caps: a month's allowance, plus 60 everyday messages a day on GPT-6 Luna, DeepSeek V4.1 Flash, GLM 5.3 Flash.
What llmwise Pro gives you, model by model
Pick any model, chat or image, and any plan: the count is worked out from the prices llmwise charges.
31messages a month
Up to 31 GPT-6 Astra messages a month on Pro, if all of the month's allowance goes to it. A $10 top-up adds 25 more.
