ChatGPT Plus vs llmwise Pro, side by side
ChatGPT Plus against the llmwise plan at the same price, model by model.
| What | ChatGPT Plus | llmwise Pro |
|---|---|---|
| Price | $20 a month | $20 a month + tax |
| Limit published as a number | No: an estimated range, in Work and Codex | Yes, for every model, shown before you send |
| GPT-6 Astra | In Work and Codex, not in Chat: 5–45 every 5 hours, estimated | up to 31 a month |
| GPT-6 Sol | Listed; no published count | up to 125 a month |
| GPT-6 Luna | Listed; no published count | 60 a day |
| AI families in one chat | 1 (GPT) | 8 |
ChatGPT Plus's cells: OpenAI's own pages, checked October 1, 2026. Ours: llmwise's plans. A monthly count is the ceiling for one model, if no other model uses the allowance.
Each count above sits under its plan's fair-use cap on monthly AI spending (Pro's, $7.50). Typical messages never reach it; very large ones and heavy research reach it sooner. Every limit, explained.
When is ChatGPT Plus the better buy?
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 chat, though it makes voiceovers and music.
More of one family (our reading): if GPT is all you use, Plus is built for it, while llmwise shares one allowance across 20 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.
8 AI families in one chat, 20 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 Claude Haiku 5.5, GPT-6 Luna, DeepSeek V4.1 Flash, GLM 5.3 Flash.
How many messages does llmwise Pro give on each 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.
Long chats, top-ups and every plan side by side are in the full message calculator.
