Gemini 3.5 Flash vs. Grok 4.5: which is better?

This comparison is based on QueryWise data, not on manufacturers’ marketing claims. We look at the overall rating, separate coding and reasoning scores, response speed, context-window size, and the approximate cost of a single query.

Which model is stronger overall?

Gemini 3.5 Flash currently scores 8.7 out of 10 and ranks 10 in the QueryWise leaderboard. Grok 4.5 stands at 9.2 and ranks 6. Grok 4.5 is ahead on the current score; use that figure as your starting point if you need one all-purpose choice.

The gap between the models is not dramatic. Both handle everyday text analysis, information structuring, and explanations of complex topics with confidence. However, Grok 4.5 scores 9.4 for coding versus 9.3 for Gemini 3.5 Flash. The reasoning picture is similar: 9.2 versus 9.1.

In practical terms, Grok 4.5 currently looks preferable for tasks that require several reasoning steps or careful work with code. That does not make Gemini 3.5 Flash a weak model. For everyday prompts, you may not notice a difference at all, especially when the question is short and clearly phrased.

Speed and pricing in tenge

According to our telemetry, the median response from Gemini 3.5 Flash takes 11 seconds, while Grok 4.5 takes 16 seconds. Gemini is noticeably faster in the current measurement. That helps when you are checking dozens of text variants, debugging code quickly, or sending the model many short questions in succession.

Grok 4.5 responds more slowly, but there is no meaningful price difference: an average query costs about 10 ₸ with Grok 4.5 and around 10 ₸ with Gemini 3.5 Flash. For a single query, the amount is barely noticeable. With regular use, waiting time and the number of iterations matter more than price. If the model solves the task on the first attempt, a few extra seconds may be a reasonable trade-off. If you are simply asking it to rephrase a paragraph, Gemini’s speed advantage is more compelling.

In our telemetry, both models have 100% reliability. This is not a promise of error-free output: the metric means that responses were successfully available during the measurement period, not that they contained no factual errors. Medical, legal, and financial decisions still require review by a qualified professional.

Context and task types

Gemini 3.5 Flash supports a context of 1M, while Grok 4.5 has a window of 500K. Gemini’s larger context is useful for long documents, extensive conversations, and projects where you need to keep a lot of source material in view.

Where Gemini 3.5 Flash is more practical

Imagine that you need to break down a long contract into clear points, compare several versions of a technical specification, or find contradictions in a large team conversation. Here, Gemini’s context advantage may matter more than a small difference in the overall score. The model is also convenient for quick drafts: a response arrives in 11, and the average query costs about 10 ₸.

Where Grok 4.5 is preferable

For debugging a function, finding a logic error, or preparing a step-by-step solution, Grok 4.5 currently looks stronger: 9.4 versus 9.3 in coding and 9.2 versus 9.1 in reasoning. For example, if an application starts crashing after a dependency update, Grok is more likely to help as a partner for testing hypotheses one by one. Its current reasoning lead also matters for learning algorithmic problem-solving.

There is also a simple everyday test. Upload the same code fragment to both models, ask them to explain the error, and then provide a clarification. Compare not the polish of the first answer, but how the models respond to corrections. On QueryWise, the two models score close to each other, so it is easy to see where they agree and where one confidently goes off track.

The honest verdict

If you want the overall leader by the current ranking, choose Grok 4.5: this model currently has the higher score — 9.8? No, that value belongs to the leader of the entire ranking, so it is more accurate to use Grok 4.5 and its current score, 9.2 or 8.7 depending on the model. To be clear, QueryWise updates these values automatically, and the winner may change.

For programming and complex reasoning, the current choice is Grok 4.5. For long materials and fast, short queries, choose Gemini 3.5 Flash. If minimizing wait time matters most, go with Gemini; if the quality of multi-step analysis matters more, start with Grok. Their prices are practically identical, both models are available on QueryWise from Kazakhstan, and both support payment in tenge and interfaces in Russian and Kazakh.

We added it on release day and ran it through the same set of real-world prompts as the other models in the leaderboard. So this is not an impression formed after a couple of lucky conversations, but a comparison under equal conditions. You can start with three free questions, which is enough to test the model on your own task.
