GPT-5.4 mini vs Kimi K3.1 Pro — which is better?

Answer quality: the difference is clear

In the QueryWise ranking, GPT-5.4 mini is in 33 place with a score of 5.4 out of 10. Kimi K3.1 Pro ranks 3 and scores 9.5 out of 10. By the current score, Kimi K3.1 Pro is ahead. This is not a minor gap that can be dismissed as the result of one random prompt: the models sit at different levels in the overall assessment.

For GPT-5.4 mini, QueryWise separately reports 7.5 for coding and 8.6 for reasoning. Kimi K3.1 Pro’s scores in these two subcategories have not yet been published on its comparison card, so assigning precise results would be misleading. Its overall score of 9.5, however, already gives a useful practical signal: for most mixed tasks, Kimi looks like the stronger choice.

We ran both models through real-world questions. Given the prompt “compare the terms for early termination of a lease in Kazakhstan and highlight the clauses that should be checked with a lawyer,” both can produce a useful analysis, but the final text should be checked against the primary source. QueryWise is an assistant, not legal advice. GPT-5.4 mini gives a focused explanation; Kimi is more likely to maintain a long structure without losing individual conditions.

In QueryWise, you can give both models the same question and see where they agree and where they differ. That is more useful than choosing by name alone: a disputed fact immediately signals the need for additional verification.

Speed and price in tenge

There is not yet enough telemetry on the median response speed of either model, so we will not make up timings. QueryWise is still collecting data, and this metric may change once enough requests have accumulated.

The average question costs about 10 ₸ for GPT-5.4 mini and about 10 ₸ for Kimi K3.1 Pro. In practice, this is an unusual case: the better-performing model does not require a separate budget. If you are reviewing one document or asking for a small script, the price difference has little impact on the decision. What matters more is the chance of getting an answer that does not need to be rewritten.

Both models are available in QueryWise from Kazakhstan: payments are processed in tenge, the interface is available in Russian and Kazakh, and new users receive three free questions. That is enough to test them on your own tasks. Start with one challenging prompt, not a greeting.

Context and task types

GPT-5.4 mini has a context window of 400K, while Kimi K3.1 Pro has 1M. Kimi’s larger context is useful when you need to upload a long contract, technical documentation or several files and connect the details across them. But window size alone does not guarantee accuracy: the model can still misunderstand a clause or invent a source.

Imagine an evening task: review a 200-page supply contract and find notice periods, penalties and conditions for unilateral termination. Kimi K3.1 Pro looks preferable here thanks to its 1M context. GPT-5.4 mini is better suited to a short excerpt, a precise summary or checking one specific question.

Another scenario is a small coding task. For example: “Write a Python function that reads a CSV containing Kazakhstani phone numbers, normalizes the format and returns a list of errors.” On the current metric, GPT-5.4 mini scores 7.5 for coding. This is one of its strengths: you can expect a clear explanation of the logic and a convenient starting point for further edits. Kimi is worth using when the code comes with extensive documentation or several related files.

GPT-5.4 mini’s reasoning score is 8.6. It works well for step-by-step analysis of a project budget, a table of conditions or a learning task where transparent logic matters. When making financial decisions, verify the figures, and remember that the model is not a financial adviser.

The honest verdict

If you need one model for long documents, complex mixed prompts and the strongest overall quality, choose Kimi K3.1 Pro: its current score of 9.5 puts it ahead of GPT-5.4 mini at 5.4. This is our choice when missing one condition would cost more than a few extra seconds of review.

GPT-5.4 mini does not lose at everything. For coding, short explanations and tasks that call for a compact answer based on a clear excerpt, it remains a practical option. Its coding score is 7.5, its reasoning score is 8.6, and it costs around 10 ₸ per average question. If you need an affordable everyday assistant without a long context window, starting with it makes perfect sense.

The current ranking gives a simple conclusion: Kimi K3.1 Pro is ahead, while the overall QueryWise leader is Claude Opus 5.5 with a score of 9.9. Choose GPT-5.4 mini for focused coding and concise analysis; choose Kimi K3.1 Pro when the volume of text is large and you need a stronger all-purpose result.
