DeepSeek V4 Pro or GPT-5.6 Sol — which is better?

On paper, these are competitors in the same class: both are available on QueryWise from Kazakhstan, accept payment in tenge, and work with interfaces in Russian and Kazakh. New users get three free questions to start with — enough to test the models on their own tasks instead of arguing over someone else’s benchmarks.

We added it on release day and have watched it ever since, focusing not only on polished demos but also on how the model behaves with everyday prompts. For this comparison, we used current QueryWise metrics. They update every hour, so the live values are intentionally shown below.

Quality: GPT-5.6 Sol has the edge

On the QueryWise leaderboard, GPT-5.6 Sol ranks 2th with a score of 9.8 out of 10. DeepSeek V4 Pro is in position 14 with 7.8. By the current score, GPT-5.6 Sol is ahead — the main answer for anyone looking for one versatile model without a lengthy selection process.

The gap is clearer on specific tasks. In coding, GPT-5.6 Sol scores 9.9, while DeepSeek V4 Pro scores 8.1. Both models perform convincingly when generating a function, refactoring a small project, or finding an SQL error, but GPT more often delivers a ready-to-use result with fewer manual fixes.

For reasoning, the scores are 9.5 for GPT-5.6 Sol and 9.0 for DeepSeek V4 Pro. DeepSeek is not a weak option here: it handles conditions, constraints, and multi-step tasks well. But when the question involves olympiad-style logic, code architecture, or a contradictory specification, GPT-5.6 Sol more often keeps the reasoning on track.

Speed and price in tenge

GPT-5.6 Sol’s median speed in QueryWise telemetry is 17 seconds. There is not enough data for DeepSeek V4 Pro yet, so we will not invent a figure. This limitation matters: a fast model feels nicer in a conversation, but a few extra seconds rarely matter if the answer later has to be checked and rewritten.

An average question to GPT-5.6 Sol costs about 25 ₸, compared with roughly 10 ₸ for DeepSeek V4 Pro. That is a noticeable difference. With dozens of prompts per day, DeepSeek saves money, especially for drafts, translations, headline variations, or simple code errors.

My practical takeaway on cost is this: DeepSeek V4 Pro is good for high-volume, low-cost prompts, while GPT-5.6 Sol is for tasks where the cost of a mistake exceeds the price of one question. For a student, freelancer, or small team, that may matter more than the ranking gap.

Context and task types

DeepSeek V4 Pro’s context is 1M, while GPT-5.6 Sol’s is 1.1M. Both windows are enormous for a normal chat. In practice, that means you can upload a long technical specification, several files, or a large conversation excerpt without splitting everything into dozens of messages.

Choose DeepSeek V4 Pro when you need an inexpensive Python script draft quickly, an explanation before an exam, or a comparison of several possible solutions. For example, the model can break down a formula, create a study plan, and then rewrite the explanation in simpler English. For users in Kazakhstan, a bilingual workflow is also useful: ask for the answer in Russian and the terms or a brief summary in Kazakh.

GPT-5.6 Sol is a better fit for complex programming, analysis of a large codebase, and tasks with multiple conditions. It is the choice for API migrations, pull-request reviews, detailed documentation, or checking a calculation where one missed detail could ruin the whole result. Even a strong answer still needs verification: QueryWise helps, but it does not replace a doctor, lawyer, or financial adviser.

On QueryWise, you can run both models side by side and see where they agree and where they suggest different solutions. This is more useful than an abstract ranking: one model may explain the idea better, while the other may spot an implementation error.

An honest verdict

For coding and complex analysis, the current numbers make GPT-5.6 Sol the winner: it has the higher overall score, a stronger coding result, and a slightly better reasoning score. If you want the highest-quality answer regardless of price, choose GPT-5.6 Sol at its current 9.8.

For economical daily use, my choice is DeepSeek V4 Pro. It costs about 10 ₸ per average question and maintains a strong reasoning result of 9.0. It is a dependable workhorse for drafts, learning, and routine tasks.

So, GPT-5.6 Sol is currently ahead, while the overall QueryWise leader is Claude Fable 5 with a score of 9.8. DeepSeek V4 Pro does not lose on every front: it simply offers a lower price and a slightly smaller quality margin. Before paying, ask both models the same challenging question of your own — QueryWise’s three free prompts make it easy to start without risk.
