Claude Opus 5 or 5.5: which is better according to QueryWise?

Quality: 5.5 takes the top spot comfortably

Claude Opus 5.5 is currently ahead by score in the QueryWise ranking: the model has 9.9 out of 10, while its position in the leaderboard is Claude Opus 5.5. Claude Opus 5 currently stands at 9.0 out of 10 and 7. This is more than a cosmetic gap. Claude Opus 5.5 is now at the top of the ranking, while Claude Opus 5 sits noticeably lower.

Opus 5 has one published sub-score: its coding score is 9.5 out of 10. That is a strong result for code-related work, especially when you need to diagnose an error, suggest a module structure, or find a weak spot in an SQL query.

So it would be unfair to declare it the winner in either category. The overall winner is clear: by the current score, Claude Opus 5.5 is ahead.

Price and speed: Opus 5.5 costs less

In QueryWise, an average question to Claude Opus 5 costs approximately 22 ₸, while Claude Opus 5.5 costs around 18 ₸. The difference favors 5.5: the model with the stronger overall rating also costs less per typical request. That matters more than it may seem for regular work. After a hundred questions, the gap becomes a noticeable sum, especially when you are working through long documents or refining an answer several times.

There is not yet enough telemetry to compare the models by median response speed. QueryWise therefore cannot honestly promise that one is faster. Price is clearer than speed here: Claude Opus 5.5 wins on cost.

Both models are available to users in Kazakhstan: payments are processed in tenge, the QueryWise interface is available in Russian and Kazakh, and new users get 3 free questions. QueryWise displays their answers side by side, so you can see where the wording matches and where one model adds an unnecessary hypothesis or misses a condition.

Million-token context: the task matters more than the volume

Claude Opus 5 and Claude Opus 5.5 have the same context window: 1M for the first and 1M for the second. In practice, this means both are suitable for large inputs. For example, you can upload a lengthy contract and ask them to find penalty clauses, termination deadlines, and contradictions between sections. The response still needs to be checked: QueryWise is not a substitute for a lawyer.

Claude Opus 5 is a logical choice when the task is code-focused and the cost of each request matters. Suppose your Python service has accumulated several errors over the evening: a model with a coding score of 9.5 can trace the call stack, explain the failure, and suggest a fix. Ask it not only to write a patch, but also to show which test should validate it.

Claude Opus 5.5 is the more sensible first choice for a complex, multi-part request. For example: compare two versions of a technical specification, highlight the changes, create a migration plan, and separately flag areas where the data is insufficient. Here, the overall result 9.9 matters more than assumptions about specialization. Still, do not treat the model uncritically as a source of truth: ask for links to the original excerpts and verify them.

For study, the difference appears in the working style. If you need to work through a 200-page contract or textbook in one evening, both models benefit from their 1M and 1M windows. If the question is narrow, such as “why does this code produce a race condition?”, Claude Opus 5’s known coding result gives it a clear argument in favor of choosing it.

An honest verdict for users in Kazakhstan

For general-purpose tasks, the current QueryWise winner is unambiguous: Claude Opus 5.5, with a score of 9.9. It is also cheaper per average question, so Claude Opus 5.5 looks like the better buy for regular use.

Claude Opus 5 is not a bad model. Its coding score of 9.5 remains strong, and its price of 22 ₸ may make sense if you specifically need code analysis and want to compare several possible answers. But if you are choosing one model without a narrow specialization, I would pick Claude Opus 5.5: it leads on the overall score and costs less per average request.

You can try both models in QueryWise without a separate upfront payment: 3 free questions are available, along with Russian- and Kazakh-language interfaces. For medical, legal, and financial decisions, use the answers as reference assistance, not as professional advice.
