    If you’re in Leeds on opening day, please stop by and say hello. Coffee is on us all day, and we’d love to welcome you into the new space.
    
    Thank you for making room for Crumb & Co. in your routine. We can’t wait to meet more of our neighbours.

GPT-6 Sol and Grok 4.7 on every plan

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

Messages on GPT-6 Sol and Grok 4.7, plan by plan
PlanPriceGPT-6 SolGrok 4.7
Free$0In the one-time trial of 5 messagesIn the one-time trial of 5 messages

Studio$200 a monthUp to 2,000 a monthUp to 4,000 a month

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: 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 twice as many messages: up to 250 messages a month on Pro, against up to 125 messages a month for GPT-6 Sol.

  • Context window

    GPT-6 Sol 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

    Both are in the free trial.

  • Where messages go

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