ChatGPT Pro'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 (Ultra's and Studio's, $42 and $85). Typical messages never reach it; very large ones and heavy research reach it sooner. Every limit, explained.
When is ChatGPT Pro the better buy?
Speed: Pro 500 ($500) is the only tier with Astra Ultrafast, the fastest response time on ChatGPT's pricing page.
Codex, OpenAI's coding agent, at its highest limits, which llmwise doesn't have, and voice: llmwise has no voice chat, though it makes voiceovers and music.
More of one family (our reading): the whole plan goes to GPT, while llmwise shares one allowance across 20 models.
Where llmwise is different
A published count on every model, shown before you send. On llmwise Ultra ($100): up to 225 Claude Fable 5.1 messages a month, 450 on Claude Opus 5.5 or 900 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 200 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 Ultra give on each model?
Pick any model, chat or image, and any plan: the count is worked out from the prices llmwise charges.
225messages a month
Up to 225 GPT-6 Astra messages a month on Ultra, 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.

ChatGPT Pro vs llmwise: your questions
How many GPT-6 Pro messages does ChatGPT Pro include?
OpenAI doesn't publish a number now (checked October 1, 2026). Its help center says Pro plans with higher usage allowances get higher limits for Pro models, and that ChatGPT Work and Codex have separate allowances. llmwise counts every model: up to 225 GPT-6 Astra messages a month on Ultra.
Is GPT-6 Pro the same model as GPT-6 Astra?
GPT-6 Pro in Chat is powered by GPT-6 Astra, OpenAI says. llmwise has GPT-6 Astra on Pro and higher plans: up to 225 GPT-6 Astra messages a month on Ultra ($100) and up to 500 GPT-6 Astra messages a month on Studio ($200).
Can I still buy Pro 200?
Yes. OpenAI's help center says Pro 200 is available for new subscriptions again, with a lower usage allowance unless you're eligible for grandfathering; it had paused new sign-ups on September 10, 2026. Pro 200 subscribers from before keep their old allowance through October 29, 2026.
What does Pro 500 add?
Astra Ultrafast, which OpenAI includes on Pro 500 only, and the most included usage of the three tiers, for $500 a month. Keeping a grandfathered Pro 200 allowance doesn't add Ultrafast.
