Gemini 3.1 Pro or Grok 4.5 — which is better?

We added this pair to QueryWise on the day Grok 4.5 launched and ran both models through identical scenarios: programming, reasoning, long-context work, and everyday questions. The difference here is not simply Google versus xAI. What matters more is that one model wins on context depth, while the other delivers a stronger overall result and has already demonstrated measured stability.

Answer quality: Grok 4.5 leads

In the current QueryWise ranking, Gemini 3.1 Pro is in position 12, with a result of 8.2 out of 10. Grok 4.5 ranks 6 and scores 9.2 out of 10. So the honest answer to “which is better on average?” is Grok 4.5. Claude Fable 5 currently remains at the top of the QueryWise ranking with a score of 9.8, meaning neither of these models is in first place.

For programming, Gemini scores 9.1, while Grok scores 9.4. At the current values, Grok 4.5 is ahead in this area. For coding, that can show up in the details: the model holds API requirements more accurately, forgets to handle errors less often, and does a better job explaining why a particular snippet does not work.

The reasoning scores are 9.2 for Gemini and 9.2 for Grok. The gap is smaller here, so the choice depends on the task format. Both models can break down a problem step by step, find a contradiction in a text, or check a calculation. But for an answer that will go into a production project, I would first look at Grok 4.5: its overall QueryWise score is higher.

Speed and price in tenge

For Grok 4.5, the median response speed in our telemetry is 16 seconds, with 100% reliability. There is not yet enough data to assess Gemini 3.1 Pro fairly, so its QueryWise speed indicator is shown as —. That is not a reason to label one model slow: short answers and long analyses have different latency profiles, and the Gemini sample has not reached the required size.

The average price per question in QueryWise is ≈10 ₸ for Gemini and ≈10 ₸ for Grok. For users in Kazakhstan, the practical takeaway is simple: price alone does not settle the debate. Ten questions cost roughly a few hundred tenge, but long prompts, large files, and follow-up requests can use more. Before sending a complex task, it is worth checking the current estimate in the interface.

Both models are available in QueryWise from Kazakhstan: payments are processed in tenge, the interface is available in Russian and Kazakh, and new users get three free questions to start. We often run the same prompt in both tabs, which makes it easy to see where the answers align and where a model starts confidently inventing details.

Context and task types

Gemini 3.1 Pro has a context window of 1M, while Grok 4.5 has 500K. In practice, this makes Gemini an interesting choice for a large batch of source material. For example, you can upload several thesis chapters and ask it to build an argument map, find repetitions, and suggest an editorial revision plan. For this kind of request, extra context matters more than a difference of a few seconds.

Grok 4.5 is a sensible choice for programming when you need a quick error analysis, function refactoring, or test generation based on existing code. Its current coding result is higher than or comparable to Gemini’s depending on the latest values, while its measured reliability makes it useful for a series of short iterations. Still, you need to run the code: a ranking does not replace tests.

Both models work well for studying, but in different roles. Gemini is more convenient for comparing several sources and explaining a topic at different levels of difficulty. Grok works well as a reviewer: give it your math solution, essay outline, or SQL query and ask it to find weak points. In medical, legal, and financial matters, these are assistants only, not substitutes for a professional.

The honest verdict

If you want one general-purpose choice based on the QueryWise ranking, choose Grok 4.5: it is ahead by the current score. For long documents and multi-step analysis, the advantage may shift to Gemini 3.1 Pro thanks to its 1M context. For fast coding iterations and tasks where proven stability matters, Grok 4.5 looks stronger, with a median speed of 16 seconds and 100% reliability.

My practical advice for Kazakhstan is simple: start with the three free questions in QueryWise, give both models the same task, and compare not the elegance of the wording but the number of corrections required. By the current figures, the overall winner is Grok 4.5, but the best tool for a large folder of documents may be different.
