  • GPT-6.1 Terra

    Passed: Graded 4.0 of 5 on average (lowest 3).

    In Q3, teams across the company worked together to put a more customer-focused approach into practice. This improved customer retention measures by 12% and reduced the pace of customer churn among enterprise customers by 0.3 percentage points. We also adjusted customer contact points across channels to make better use of available resources.

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

    They cost the same in llmwise: up to 250 messages a month on Pro on either.

  • Context window

    GPT-6.1 Terra 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.

  • Free trial

    GPT-6.1 Terra and Grok 4.7 are both in the 2-day free trial of Plus or Pro.

  • Where messages go

    GPT-6.1 Terra: Sent to OpenAI directly. Grok 4.7: Served through OpenRouter by xAI alone, on an endpoint that doesn't store or train on prompts.

If the provider failsIf OpenAI fails before the reply starts (an overload, a server error, a dropped connection), llmwise sends the same request to GPT-6.1 Terra through OpenRouter instead.xAI is its only host, so there's no other host to move to: if xAI fails, send the message again or pick another model.

API prices are what our model catalog lists (GPT: OpenAI's list price; Grok: xAI's price, served through OpenRouter). In llmwise you pay per message, not per token: the counts above are what you get.

GPT-6.1 Terra or Grok 4.7?

From the facts above and our test runs: the rest is how their answers suit your work, which one chat can show you.

  • Pick GPT-6.1 Terra: it costs its maker less to run ($0.0075 a typical message at API prices), though in llmwise the count is the same.
