GPT-5.6 Luna or Grok 4.5 — which is better?

The comparison below uses current QueryWise data. The ranking is updated every hour, so the figures on this page are deliberately replaced with live values. That is more useful than leaving an outdated table online that could become misleading within a week.

Which model leads in quality

Grok 4.5 currently leads by overall score: Grok 4.5 is in Claude Fable 5 place with a result of 9.8. GPT-5.6 Luna is ranked 9 with a score of 8.7, while Grok 4.5 is in 6 place with 9.2.

The gap between them is better understood as a guideline than a verdict. In a real prompt, much depends on the wording, language, and volume of the source data. We added GPT-5.6 Luna to QueryWise on release day and immediately tested it on practical scenarios: coding, document analysis, explanations of complex topics, and questions in Russian.

Coding and reasoning

For programming, GPT-5.6 Luna scores 9.3, while Grok 4.5 scores 9.4. If you need to find a bug in a function, write an SQL query, or explain why a test is failing, both models perform seriously well. If Grok 4.5 has a small lead, it is worth choosing for debugging and tasks that require checking several conditions step by step.

GPT-5.6 Luna currently has — for reasoning, compared with 9.2 for Grok 4.5. For logic problems, project planning, and comparing options, these figures are more informative than the overall score. If you need a multi-step analysis with contradiction checks, favor the model with the higher current reasoning value.

Speed and prices in tenge

Grok 4.5 has a median speed of 16 seconds in QueryWise telemetry. There is not enough data for GPT-5.6 Luna yet: its live metric is shown as —. It is therefore too early to label Luna either fast or slow.

The two models cost approximately 10 ₸ and 10 ₸ per average question, respectively. For a typical user, that means price is barely a meaningful deciding factor. The difference becomes noticeable with a large number of prompts or long dialogue chains, but in a normal session, answer quality and waiting time matter more.

According to our telemetry, Grok 4.5 has 100% reliability. There is not yet enough data to calculate reliable statistics for GPT-5.6 Luna. That does not mean Luna makes frequent mistakes; the sample is simply still too small for a fair percentage.

Context and task types

GPT-5.6 Luna works with a context of 1.1M, while Grok 4.5 works with 500K. Luna has a clear practical advantage here: it is more convenient for handling a long contract, a large report, several code files, or a conversation history and turning them into one coherent conclusion.

With 500K of context, Grok 4.5 is better suited to more compact tasks. For example, you can ask it to review the architecture of a small service, create a study plan for an exam topic, and then challenge its own conclusion. For these prompts, precise reasoning and consistent answers matter more than the maximum amount of input data.

There is also a distinctly Kazakhstani everyday scenario: upload the rules of an internal competition, ask the model to extract the requirements, and then prepare a letter in Russian or Kazakh. For a large document set, I would start with GPT-5.6 Luna. For a short question with several constraints, I would start with Grok 4.5. In QueryWise, they can answer side by side, so you can immediately see where the models agree and where one of them missed an important detail.

Choose honestly based on the task

For coding: does the model with a Grok 4.5 score lead according to the current measurement? No — here you need to look specifically at 9.3 versus 9.4. If Grok 4.5 is higher, choose it for debugging; if a ranking update puts GPT-5.6 Luna ahead, its advantage will appear directly in the live data.

For long documents: my choice is GPT-5.6 Luna because of its 1.1M context. For fast, short tasks: Grok 4.5 is more practical because its median speed is already measured at 16 seconds. For complex reasoning: use — and 9.2 as your reference; Grok 4.5 currently leads the overall ranking.

The takeaway is simple: Grok 4.5 is the best choice by the current QueryWise score, but GPT-5.6 Luna should not be dismissed. It is especially appealing for people who work with lengthy materials. Both models are available to users in Kazakhstan, accept payment in tenge, offer interfaces in Russian and Kazakh, and let you start with three free questions.
