GPT-6.1 Sol or Claude Opus 5.5 — which is better?

Quality: the leader does not change every hour

In the QueryWise ranking, GPT-6.1 Sol is in 6 place with a score of 9.1 out of 10. Claude Opus 5.5 is in 1 place with 9.9 out of 10. So the direct answer to “which model is better overall?” is Claude Opus 5.5, with a current score of 9.9.

We tested both models with real questions rather than relying on polished demo answers. For example, the request “compare early repayment terms in two Kazakhstan loan agreements and identify the clauses to check with the manager” requires careful context handling, accurate amounts, and a clear distinction between conclusions and advice. Claude Opus 5.5 is especially useful here when a large document package is uploaded to the chat. GPT-6.1 Sol responds more compactly and produces a checklist faster, but complex caveats should be verified against the source text.

If you need an answer for a specific task, the overall ranking does not replace testing the models on your own example.

Speed and pricing in tenge

There is not yet enough reliable evidence to promise that either model will consistently be faster. In a working chat, speed depends on the prompt length, the file, and the current load.

An average question costs approximately 10 ₸ with GPT-6.1 Sol. For Claude Opus 5.5, the cost is approximately 18 ₸. For a short email, the difference may seem minor. But if you need to review dozens of contract pages, prepare several customer replies, or run a large set of SQL queries each day, the costs become visible in the budget.

GPT-6.1 Sol looks more sensible for frequent short requests if its current price remains lower. Claude Opus 5.5 justifies a more expensive request when an error in a long chain of reasoning would cost more than a few extra tenge. QueryWise shows prices in tenge, so there is no need to convert a dollar-based tariff.

Context and task types

Claude Opus 5.5 has a context window of 1M. The current value for GPT-6.1 Sol is 1.1M. This difference matters for documents, message archives, and large repositories: a model with a larger window can retain more source material in one request, although context length alone does not guarantee a correct conclusion.

Consider three work scenarios. You need to review a 200-page contract in one evening and create a risk table. Claude Opus 5.5 is the better choice here because long material fits into the task more conveniently. You need to quickly rewrite an email to a supplier in Almaty in neutral business Russian and create a Kazakh version. GPT-6.1 Sol is more practical if price and a short editing cycle matter.

Both models are useful for studying, but prompts should be specific: “explain the topic with an example and create five exercises with answers.” In mathematics, law, medicine, and finance, answers should not be treated as professional advice. This is especially important for loans, taxes, and treatment: a model can make a convincing mistake.

Which model should you choose in QueryWise?

If you want the highest overall score, choose Claude Opus 5.5: the current leader is determined by the 9.9 score, not by a marketing promise. For long documents, Claude Opus 5.5’s advantage is linked to its 1M window. For frequent short questions, GPT-6.1 Sol may be more cost-effective at 10 ₸ versus 18 ₸ for Claude Opus 5.5.

When the scores are close, use the answer that preserves the constraints of your specific task better. When the current leader is clearly ahead, there is no reason to call the models equal for the sake of diplomacy.

In QueryWise, you can ask both models the same question and see where they agree and where they differ. This is more useful than choosing blindly based on the model name. Both models are available in Kazakhstan, accept payment in tenge, support RU/KK interfaces, and provide three free questions at the start.
