GPT-6 Astra and Grok 4.7 on every plan

Whether the one-time free trial reaches each model, then each paid plan's messages on it.

Prices don't include tax, which is added where it applies and shown before you pay. A paid plan's month is one allowance shared by every model, so each monthly count is the most you get if all of it goes to that model. It renews each billing period; everyday models refill daily at 00:00 UTC. Long chats count more per reply. 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.

What differs

  • Messages on Pro

    Grok 4.7 gets eight times as many messages: up to 250 messages a month on Pro, against up to 31 messages a month for GPT-6 Astra.

  • Context window

    GPT-6 Astra takes up to 1.05M tokens; Grok 4.7 up to 500K tokens. A chat in llmwise holds up to 200k tokens, which fits in either, so the difference shows only through each maker's own API.

  • Images and PDFs

    Both read images. Both take a PDF as the whole file, pages and all.

  • On Free

    Neither is in the free trial: GPT-6 Astra needs Pro or a higher plan and Grok 4.7 needs a paid plan.

  • Where messages go

    GPT-6 Astra: Sent to OpenAI directly. Grok 4.7: Served through OpenRouter by xAI alone, on an endpoint that doesn't store or train on prompts.
