Claude Opus 5 or Grok 4.7: which is better?

Answer quality: Claude has the edge

By the current QueryWise score, Claude Opus 5 is ahead: it has Claude Opus 5 points versus the result of the other contender. Claude Opus 5.5 currently holds first place in the ranking with a score of 9.9, so neither Claude Opus 5 nor Grok 4.7 is leading the table right now.

Claude Opus 5 ranks 7 with a score of 9.0. Grok 4.7 is in 12 place with 8.3. This is more than a cosmetic gap: when handling a long prompt, Claude is more likely to preserve the conditions, response format, and relationships between different parts of the task. Grok is a sensible alternative when you need a quick draft without paying much for every question.

Claude Opus 5 has a separate coding result of 9.5. Coding can therefore already be compared, but QueryWise does not yet provide an honest numerical winner for reasoning.

Price in tenge and speed

An average question to Claude Opus 5 costs about 22 ₸, compared with roughly 10 ₸ for Grok 4.7. At the current rates, Grok is cheaper. The difference may seem small across a dozen short prompts, but daily work with large documents or code quickly turns it into a noticeable amount.

Calling one model faster would therefore be speculation. In QueryWise, choose based on the task and the price rather than an unverified promise about response times.

What does this mean in practice? If you need to check several SQL query variants in one evening or get an explanation of an error in a small script, Grok 4.7 is attractive because of its price. When an incorrect answer would cost more than the tenge you saved, Claude Opus 5 is the more defensible choice.

Context and task types

Claude Opus 5 works with a context of 1M, while Grok 4.7 offers 500K. That is a meaningful difference for long material. For example, you can upload a lengthy contract and ask the model to find contradictions between sections, compare deadlines, and compile a list of disputed points. Claude is better suited to this kind of step-by-step analysis, especially when the task requires keeping many conditions in mind.

There is also a more everyday scenario: a user provides a client conversation, a technical specification, and an older project version, then asks for a correction plan. Claude Opus 5 is more convenient when the answer needs to draw on the full set of materials rather than just the last few paragraphs.

Grok 4.7 is a reasonable choice for short iterations: rewriting an email, sketching a presentation outline, explaining a code fragment, or quickly suggesting headline options. Since it costs less, sending a series of trial prompts is less painful. But a larger context does not guarantee correctness on its own: facts and links still need to be checked.

We tested the models with a specific question: “Compare two versions of a Python function, find the error in time-zone handling, and suggest tests for switching between Almaty and London.” Claude Opus 5 handled the date-transition condition better and connected the fix to the tests. Grok 4.7 produced a useful draft, but it required an additional check of the edge case around midnight. This is a good example of the difference between a cheaper first answer and more careful work.

How to choose a model in QueryWise

For coding, the winner is Claude Opus 5: its result on this measure is 9.5, while Grok 4.7 has no separate score. Claude also wins for long-form analysis thanks to its 1M context versus 500K for Grok.

For inexpensive everyday prompts, the choice is different: Grok 4.7 offers better value, currently costing around 10 ₸ per average question. It works well for editing text, brainstorming ideas, or checking a simple formulation when you are prepared to review the result yourself.

Claude Opus 5 is ahead on the current score. My practical verdict is this: choose Claude Opus 5 for code, long documents, and tasks where answer coherence matters; choose Grok 4.7 for frequent short prompts on a limited budget. This is not advice for medical, legal, or financial decisions: such answers should be reviewed by a qualified professional.

Both models are available from Kazakhstan in QueryWise: payments are made in tenge, the interface is available in Russian and Kazakh, and new users receive three free questions to start. It is useful to send the same prompt to both models: you will see where their answers agree and where one of them starts making things up.
