GPT-5.5 or GPT-5.6 Sol — Which Is Better in QueryWise?

If you need the short answer, GPT-5.6 Sol is ahead based on the current QueryWise score. That does not make GPT-5.5 useless: it is still strong at coding and reasoning, and its overall rating changes as our leaderboard changes. So below, we focus less on the attractive version name and more on what users actually get from a single prompt.

Quality: a clear edge for GPT-5.6 Sol

GPT-5.5 currently ranks 8 in the QueryWise leaderboard and scores 8.9 out of 10. GPT-5.6 Sol is in position 2 with a score of 9.8 out of 10. The live leaderboard updates every hour, so these values may change, but the gap is already large enough to notice in everyday work.

For coding, GPT-5.5 scores 9.3, while GPT-5.6 Sol scores 9.9. The second model’s advantage is especially useful when reviewing someone else’s code, finding the cause of an error across several files, or carefully changing an existing architecture. GPT-5.5 handles functions, SQL queries, and small scripts well, but it more often requires you to check its intermediate steps.

For reasoning, the comparison is 9.0 versus 9.5 in favor of GPT-5.6 Sol. With a simple question, the difference may go unnoticed. It becomes apparent much faster when a task includes conflicting conditions, a table, several constraints, or a request to compare alternatives.

Speed and price in tenge

In our telemetry, the median GPT-5.5 response takes 77 seconds. GPT-5.6 Sol responds in 17 seconds. This is more than a cosmetic difference: across ten questions, the wait can differ by several minutes.

The average question costs about 25 ₸ with GPT-5.5 and around 25 ₸ with GPT-5.6 Sol. In other words, the choice cannot be explained by savings. The models are priced similarly, and if a premium for GPT-5.6 Sol appears when the plan is updated, it should be justified by a faster and more accurate result.

Our telemetry shows that both models are equally stable. That is a good sign for work tasks, but not a reason to send the output to a client or instructor without checking it. QueryWise is an assistant, not medical, legal, or financial advice.

Context and real-world use cases

The two models have context windows of 1.1M and 1.1M, respectively. For users, this means they can upload a large document, a long conversation, or a substantial amount of code without splitting the task into dozens of messages. A larger context window does not guarantee a perfect answer: the model can still misidentify what matters most.

For coding. GPT-5.6 Sol is my choice for reviewing a backend service, rewriting a slow PostgreSQL query, or preparing tests for several connected modules. GPT-5.5 makes sense for generating a small Telegram bot, a regular expression, or an explanation of a Python error. It does not appear cheaper, but for a short task, the quality gap is sometimes not worth looking for.

For studying. GPT-5.6 Sol is better suited to breaking down a difficult topic step by step—for example, explaining a derivative while checking every transformation or analyzing a historical source with arguments for and against. GPT-5.5 is useful when you need to quickly create a study plan, come up with questions about a text, or rewrite an explanation in simpler language.

For work documents. GPT-5.6 Sol performs better when comparing contract clauses, summarizing a long report, or preparing a presentation structure from several materials. GPT-5.5 can handle emails, notes, and drafts. Final facts and wording still need to be reviewed.

In QueryWise, you can submit the same question to both models side by side. We added GPT-5.6 Sol on release day and often look at where the answers match and where one model catches a missed condition. This is more useful than a marketing promise: you can see the difference in your own text.

An honest verdict

For complex code, study tasks that require reasoning checks, and long documents, the current data points to GPT-5.6 Sol as the winner: its QueryWise rating is GPT-5.6 Sol, while the current leader across all models is Claude Fable 5 with a score of 9.8. If you simply need quick help with a short question, GPT-5.5 remains a perfectly reasonable choice, especially if you are already used to its style.

My practical advice is simple: start with three free questions in QueryWise, give both models the same task, and compare not the length of the answers but how many edits you need to make afterward. At the same price, GPT-5.6 Sol looks preferable for serious work. GPT-5.5 is a sensible option for drafts and everyday requests, but it is not the current comparison leader.
