Claude Sonnet 4.6 or GPT-5.6 Sol: which is better?

We added Claude Sonnet 4.6 to QueryWise on release day and immediately ran it through the same scenarios we use for the other models. The result was interesting: Sonnet is strong at programming and reasoning, but GPT-5.6 Sol is currently much higher in the overall ranking. Based on the latest data, Claude is 20 in QueryWise with a score of 6.8, while GPT-5.6 Sol is 2 with a score of 9.8.

Answer quality: GPT-5.6 Sol has the edge

In a head-to-head comparison, GPT-5.6 Sol looks more versatile. Its current coding score is 9.9, and its reasoning score is 9.5. Claude Sonnet 4.6 scores 9.2 and 8.6, respectively. The programming gap is especially interesting: both models are capable of producing real-world code, but GPT is more likely to preserve the task requirements and less likely to need another round of edits.

Claude is not a weak competitor. It is comfortable for reviewing someone else’s project, working through a long technical specification, or explaining an algorithm carefully. Sonnet’s answers are usually well structured, and its reasoning is easier to follow for readers who do not want to work through several implementation options at once. But if you need the most reliable result on the first try, the current figures favor GPT-5.6 Sol.

Code and logic

GPT-5.6 Sol wins on coding: its 9.9 score is higher than Claude’s 9.2. You can see this in tasks such as fixing a TypeScript bug, writing a SQL query with several conditions, or preparing API tests. GPT more often produces a workable structure immediately, while Sonnet may offer a strong analysis but leave more final polishing to the user.

The reasoning results tell a similar story. GPT-5.6 Sol scores 9.5, while Claude Sonnet 4.6 scores 8.6. If you need to compare contract terms, find a contradiction in product requirements, or break a complex task into stages, GPT is currently more dependable. This is not medical, legal, or financial advice: the models help analyze material but do not replace a specialist.

Speed and price in tenge

According to our telemetry, GPT-5.6 Sol has a median response time of 17 seconds. We do not yet have enough data for Claude Sonnet 4.6, so we will not invent a comparison. Even when you ask several questions in a row, GPT’s delay remains manageable: the response is not instant, but you usually do not have to rerun the request because the result was incomplete.

An average question costs about 13 ₸ with Claude and around 25 ₸ with GPT-5.6 Sol. That difference matters when choosing a model. For short explanations, email drafts, and simple text transformations, Claude looks more economical. For complex code, document analysis, and tasks where a mistake costs more than one request, paying extra for GPT may be reasonable.

Both models are available from Kazakhstan in QueryWise: payments are processed in tenge, the interface is available in Russian and Kazakh, and new users get three free questions at the start. We suggest using them on the same prompt—for example, ask both models to find a bug in a small code snippet. The difference is easier to feel this way than through marketing descriptions.

Context and task types

Claude Sonnet 4.6 has a context of 1M, while GPT-5.6 Sol has 1.1M. Both models are designed for very long materials. That is useful when you need to upload a large repository, a set of internal instructions, or several textbook chapters and then ask questions without constantly recapping the source.

I would choose Claude for calm, careful work with text and long source material: editing technical documentation, comparing versions of requirements, or explaining a topic to a student in simple language. It is especially pleasant when clear wording and a consistent answer structure matter.

GPT-5.6 Sol is better suited to tasks that require reading context, calculating, checking constraints, and producing a practical result at the same time. For example, it can outline a database migration, write a function and its tests, and then explain possible failure modes. Here, its coding and reasoning advantages combine into a more confident answer.

A useful QueryWise mode is to send one question to both models. They answer side by side, so you can see where their conclusions match and where one model missed a condition or chose a debatable solution. For work tasks, this is often more valuable than blindly trusting one polished answer.

Our honest verdict

GPT-5.6 Sol is ahead on the current score, and at the present values Claude Fable 5 ranks first in QueryWise with a result of 9.8. For programming and complex analysis, my choice is GPT-5.6 Sol: its 9.9 versus Claude’s 9.2, and 9.5 versus 8.6, give it a practical advantage.

Choose Claude Sonnet 4.6 if a lower average question price—about 13 ₸—and careful work with large texts matter most. It is a good option for learning, documentation, and everyday requests. But based on the current data, GPT-5.6 Sol remains the best all-purpose choice.
