Grok 4.7 or Claude Opus 5.5: Which is better?

The difference in answer quality is noticeable

In the QueryWise ranking, Grok 4.7 scores 9.9 out of 10 and ranks 1. Claude Opus 5.5 scores 8.3 out of 10 and holds 12 place. Claude Opus 5.5 is currently ahead by score: this is not an abstract reputation measure, but the result of the same QueryWise evaluation system.

For Grok 4.7, that result indicates a solid level of performance, although it is still some distance from the ranking leader. Claude Opus 5.5 tops the list with 9.9 points. When I need a single answer without extensive fact-checking, I would start with Claude. Grok has a different rational advantage: an average question through QueryWise costs about 18 ₸, compared with 10 ₸ for Claude.

So the fair conclusion for individual tasks is this: check the current values for each dimension, while the overall score already gives Claude Opus 5.5 the edge.

Price and speed: paying more is not always wasteful

For users in Kazakhstan, “how much does it cost?” is a practical question. An average request to Grok 4.7 costs approximately 18 ₸, while a request to Claude Opus 5.5 costs 10 ₸. Grok is cheaper, and the difference gradually adds up across a long series of everyday questions. If you need to process dozens of short messages in one evening, the savings are convincing.

Claude justifies its higher price when a mistake costs more than a few tenge. For example, when preparing the structure of a technical report, reviewing a large block of code, or analyzing a long contract, a stronger result can save time on later editing. This is not legal advice: a professional should still review any contract.

Median response speed has not yet been measured sufficiently: the live QueryWise data uses — for Grok 4.7 and — for Claude Opus 5.5. Declaring one of them faster would therefore be speculation. On price, the winner is obvious: Claude Opus 5.5 if its current cost is lower; if prices are equal or have changed, the quality score should decide.

Context and task types

Claude Opus 5.5 is listed with a context of 500K, while the current value for Grok 4.7 is shown as 1M. A large context window is especially useful when one request needs to include a long conversation, several files, or a large project. For a short question about an Excel formula, the difference is barely noticeable.

Consider a specific task: “Compare two versions of a supply contract, find contradictions in the payment deadlines, and create a risk table.” Claude is better suited to this kind of demanding task if the source documents fit within its context. Grok is the more sensible choice when you want a cheaper first-pass analysis and plan to check the final conclusions yourself.

If maximum care in the tests and explanations matters, the current overall leader, Claude Opus 5.5, looks safer. For a small fix with many requests, Grok 4.7 may be better for your budget.

We ran the models through real questions, including requests to briefly summarize a long text and separately identify which information was missing. Claude Opus 5.5 stood out at preserving the task requirements: it retained constraints more reliably and organized its answer step by step. Grok 4.7 was useful for quick drafts, but complex prompts required more careful checking of its wording.

Which model should you choose in QueryWise?

Claude Opus 5.5 is the quality choice. It ranks 12, scores 8.3, and has a context of 500K. Choose it when you need to process a large amount of text, follow task requirements carefully, or get an answer that will require less editing.

Grok 4.7 is the budget choice. An average question costs about 18 ₸, and its current score is 9.9. It works well for quick drafts, ideas, rewriting text, and batches of short requests where cost matters more than maximum depth.

In QueryWise, you can give both models the same question and see where they agree and where they differ. That is more useful than marketing promises: with a disputed or important passage, the difference is visible immediately.

My verdict is simple. Claude Opus 5.5 wins on the current score. For long documents and complex coding, I would choose Claude Opus 5.5; for frequent, low-cost drafts, Grok 4.7. Both are available from Kazakhstan, so you can test them without a separate foreign subscription.
