DeepSeek V4 Pro vs. Grok 4.5 — Which Is Better?

Comparing these models by name alone makes little sense: DeepSeek V4 Pro and Grok 4.5 are built for different scenarios. We test them in QueryWise on a common scale, looking at coding, reasoning, speed, and query cost. For users in Kazakhstan, the conditions are the same: both models are available with payment in tenge, interfaces in Russian and Kazakh, and three free questions at the start.

Answer quality: Grok 4.5 has the edge

Grok 4.5 is currently ahead in the QueryWise ranking, with a result of . DeepSeek V4 Pro is in position 14, with an overall score of 7.8. Grok 4.5 ranks 6 with a result of 9.2. The current overall leader remains Claude Fable 5 with a score of 9.8, so Grok 4.5 is strong, but it still has room to climb.

For coding, DeepSeek V4 Pro scores 8.1, while Grok 4.5 scores 9.4. The advantage goes to Grok 4.5: it is more reliable at diagnosing code errors, proposing a workable solution structure, and preserving the requirements from the original brief. That difference is noticeable when reviewing a Python script, writing an SQL query, or finding the cause of a JavaScript error.

The reasoning results are closer: DeepSeek V4 Pro posts 9.0, while Grok 4.5 posts 9.2. Before tackling a difficult task, this is the metric worth checking. DeepSeek may be more convenient when you need to break down a long set of conditions step by step, compare several documents, or derive a formula carefully. Grok 4.5 is stronger when reasoning is combined with code, result verification, and several constraints at once.

Speed and price in tenge

According to our telemetry, Grok 4.5 has a median response time of 16 seconds. We do not yet have enough data for DeepSeek V4 Pro, so we will not replace observations with a guess. This is an important limitation of the comparison. If you ask short questions in a work chat, Grok 4.5’s delay is predictable, while DeepSeek’s speed still needs to be measured across real requests.

The average cost per question is approximately 10 ₸ for DeepSeek V4 Pro and around 10 ₸ for Grok 4.5. In practice, the spending level is nearly identical. Ten questions will cost roughly ten times as much as one request, but the final amount depends on prompt and response length. For regular use, it makes more sense to look for the difference not in the tariff, but in how many edits you need to make after receiving an answer.

As for reliability, our telemetry currently shows 16 for Grok 4.5? No: speed and reliability are different metrics, so we do not mix them. Grok 4.5 has a recorded reliability rate of 100%. We still do not have enough data for DeepSeek V4 Pro. We added it on release day and are collecting honest statistics instead of publishing a polished but random percentage.

Context and task types

DeepSeek V4 Pro supports a context of 1M, while Grok 4.5 supports 500K. DeepSeek’s large window is useful when you need to load lengthy technical documentation, several code files, or a thesis draft into one conversation. The model can retain more of the original detail without requiring you to paste the text again and again.

Grok 4.5 is the better choice for short and medium-sized work tasks where fast results and accurate execution matter. It works well for debugging APIs, generating tests, explaining compiler errors, and preparing a research plan. If you need to compare two contracts or analyze a large report, DeepSeek’s context advantage becomes more practical, although a specialist should still verify any legal conclusions.

For studying, DeepSeek V4 Pro works well as a patient explanatory assistant: give it a lengthy study guide and a list of topics, then ask for a structured walkthrough. Grok 4.5 is stronger at checking solutions, finding skipped steps, and handling programming tasks. Medical, legal, and financial answers from both models are guidance for orientation, not professional advice.

Which model should you choose in QueryWise?

If you want the current overall-score winner, Grok 4.5 is ahead with . That compares with 7.8 for DeepSeek V4 Pro and 9.2 for Grok 4.5 in their respective ranking cards. For development and code review, the choice leans toward Grok 4.5, whose coding score is higher at 9.4. For long documents and multi-step learning, it is sensible to start with DeepSeek V4 Pro thanks to its 1M context.

There is a simple way to avoid guessing. In QueryWise, both models answer the same prompt side by side, so you can immediately see where they agree and where one of them missed a requirement. This is especially useful before buying a subscription or when the cost of an error is higher than the price of a few questions.

My verdict: Grok 4.5 is the best overall choice based on current QueryWise data, especially for coding and tasks where consistency matters. DeepSeek V4 Pro is the more interesting option for long-context work, large source materials, and careful analysis of a complex topic. Its overall result is still lower, but the model is not a loser in every scenario.
