Claude Sonnet 5 or GPT-5.6 Sol: which is better?

This comparison produced an interesting result: Claude Sonnet 5 scores 9.0 and ranks 7 in QueryWise, while GPT-5.6 Sol scores 9.8 and sits at position 2. GPT-5.6 Sol is currently ahead by score, so it is the sensible choice when you want the strongest possible all-purpose answer without lengthy deliberation.

That said, the difference between use cases is more noticeable than the overall rating suggests. Claude Sonnet 5 costs about 10 ₸ per average question, while GPT-5.6 Sol costs around 25 ₸. For occasional complex requests, the extra cost may be justified. For regular work, especially with a high volume of prompts, the cheaper Claude looks more practical.

Answer quality: GPT-5.6 Sol leads for now

In the QueryWise rankings, GPT-5.6 Sol is clearly ahead of Claude Sonnet 5 in the overall score. Its current score is 9.8, compared with 9.0 for Claude. Claude Fable 5 is also ahead, currently holding first place with a score of 9.8. The rankings update every hour, so check the current values directly in QueryWise before publishing an important comparison.

Claude Sonnet 5 should not be dismissed. It is strong at working with code, with a coding score of 9.4. GPT-5.6 Sol scores 9.9, so it leads in programming as well. The gap here is smaller than the overall ranking might suggest: both models are suitable for reviewing pull requests, finding bugs in Python scripts, and explaining someone else’s TypeScript.

Reasoning also favors GPT-5.6 Sol: 9.5 versus — for Claude Sonnet 5. For tasks with several constraints—such as planning a database migration, spotting contradictions in requirements, or breaking a calculation into steps—GPT-5.6 Sol’s advantage is more convincing. There may be less data for Claude on this measure, so treat its figure as a current snapshot rather than a final verdict.

Speed and price in tenge

Our telemetry records a median speed of 17 seconds for GPT-5.6 Sol. There is not yet enough data for Claude Sonnet 5, so its value is shown as —. This is an important caveat: it would be unfair to call Claude slow or fast based on a handful of individual requests.

In practice, 17 seconds is a normal wait for a detailed answer, but it is not instant-chat territory. If you test several hypotheses in a row or ask the model to rewrite text, the pause becomes noticeable. Claude Sonnet 5 may be better value in a long work session because it costs about 10 ₸ versus roughly 25 ₸ for GPT-5.6 Sol.

A simple example: with ten average requests, the price difference already adds up to a meaningful amount in tenge. So GPT-5.6 Sol is the choice for quality on every prompt, while Claude Sonnet 5 suits people who want to keep spending under control. I would not pay extra for GPT to edit a simple email or write a short summary.

Context and task types

Claude Sonnet 5 has a context window of 1M, while GPT-5.6 Sol has 1.1M. This is the space available for input text and conversation history. A large context is useful when you need to load a long contract, technical documentation, research, or several files at once. It does not turn a model into a mistake-proof expert, but it reduces the need to split material into smaller parts.

For coding, I would choose GPT-5.6 Sol when the task involves designing a complex solution, reviewing architecture, or explaining a chain of errors. Its coding score is 9.9, and its reasoning score is 9.5. Claude Sonnet 5, with a coding score of 9.4, is well suited to generating functions, refactoring, and calm, step-by-step analysis. Especially when prompts are frequent and cost matters.

The picture is similar for learning. GPT-5.6 Sol is better for tasks that require comparing several approaches, finding a weak point in an argument, or preparing a detailed exam study plan. Claude Sonnet 5 is good at explaining topics in plain language, checking essays, and turning long notes into a clear structure.

For large documents, context-window size alone should not decide the winner. Accuracy when citing the source text and response discipline matter too. Ask both models to provide quotations, page numbers, or excerpts, then verify the result yourself. These are assistants, not medical, legal, or financial advisers.

Which model should you choose on QueryWise?

The current score winner is GPT-5.6 Sol. If you want one strongest option for complex coding, requirements analysis, learning, and long documents, I would choose GPT-5.6 Sol: it scores 9.8, with 9.9 in coding and 9.5 in reasoning.

Claude Sonnet 5 wins in a different situation—when the cost of regular prompts matters. It costs about 10 ₸, and its coding score is 9.4. For an editor, developer, or student asking dozens of questions each week, that may outweigh the difference in the overall score.

On QueryWise, both models answer side by side: send them the same prompt and immediately see where Claude Sonnet 5 and GPT-5.6 Sol agree and where they differ. We added Claude Sonnet 5 on release day and are continuing to collect telemetry, so we are not yet making definitive claims about its speed or reliability.

My verdict is simple: GPT-5.6 Sol is the better choice for quality and difficult reasoning, while Claude Sonnet 5 is the more sensible option for cost-conscious everyday work. Before paying, compare them on your own tasks: QueryWise offers interfaces in Russian and Kazakh, billing is in tenge, and new users get three free questions to start.
