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

It would be odd to compare these models based only on how recognizable their names are. At QueryWise, we look at real answers, the cost of a typical request, and consistency. OpenAI’s GPT-5.6 Sol currently has a score of 9.8 and ranks 2 in the QueryWise leaderboard. Grok 4.5 from xAI scores 9.2 and holds position 6.

The gap is easier to see in tasks where mistakes cost time: programming, analyzing a long document, and preparing study materials. By the current score, GPT-5.6 Sol is ahead. Still, Grok 4.5 does not look like a weak model — its results are strong enough to handle everyday requests confidently.

Answer quality: GPT-5.6 Sol has the edge

In programming, GPT-5.6 Sol scores 9.9, while Grok 4.5 scores 9.4. This is not just an abstract number: in practice, it shows how well a model keeps track of requirements, finds bugs in code, and explains fixes without unnecessary guesswork. If you write Python or JavaScript, or work with SQL queries, GPT-5.6 Sol looks like the more reliable choice at the current values.

The reasoning results look like this: GPT-5.6 Sol — 9.5, Grok 4.5 — 9.2. Grok can give a fast and perfectly sensible answer to a short logic problem, but when a task involves a chain of conditions or comparing several options, the model with the higher current result comes out ahead. For analyzing requirements, technical specifications, and complex instructions, I would choose GPT-5.6 Sol.

We added this pair to QueryWise on release day and ran them through identical scenarios instead of relying on marketing copy. According to our telemetry, do both models have reliability scores of 9.8 and 9.2? No — score and stability need to be distinguished here: each model’s reliability is 100%. Responses arrive without noticeable availability roulette, which matters more for a working service than a polished demo.

Speed and price in tenge

The median response time for GPT-5.6 Sol is 17 seconds, compared with 16 seconds for Grok 4.5. In other words, the models are effectively neck and neck on waiting time right now. Grok 4.5 is not fast enough to offset the quality gap on speed alone.

The price difference is more noticeable. An average question to GPT-5.6 Sol costs about 25 ₸, while a question to Grok 4.5 costs around 10 ₸. For one or two requests, the difference is small. With hundreds of questions a month, it becomes a real line item. For a student asking for an explanation or a quick text check, Grok 4.5 may be more practical. For a developer saving hours on debugging, GPT-5.6 Sol’s price looks justified.

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 put them in one interface for more than a polished showcase: you can send the same prompt to both models and see where their answers match — and where one starts making things up.

Context and task types

GPT-5.6 Sol has a context window of 1.1M, while Grok 4.5 has 500K. A larger context is useful when you need to include a long contract, study notes, repository, or several tables in a prompt. The model can keep more source material in a single session, so users do not have to repeat the background information constantly.

Where GPT-5.6 Sol is stronger

• Code and debugging. Provide an error, a project snippet, and the requirements for the result — GPT-5.6 Sol is better suited to working through constraints step by step.
• Large documents. For analyzing a long report, contract, or technical brief, the 1.1M context window provides a noticeable advantage.
• Complex learning. If you need a topic explained step by step, a study plan prepared, and a solution checked, choose GPT-5.6 Sol based on the current ranking.

Where Grok 4.5 makes more sense

Grok 4.5 is good for short questions, quick drafts, rewriting emails, and initial brainstorming. Its 500K context is still large enough for most everyday conversations, while its price of 10 ₸ per average question is noticeably friendlier. If you do not need to upload a large body of material and the answer does not require multi-step verification, paying extra for GPT-5.6 Sol may be unnecessary.

An honest verdict

For programming, working with long files, and complex learning, the winner is GPT-5.6 Sol when you consider the current score of 9.8 and the category-by-category comparison. Choose GPT-5.6 Sol for maximum quality and a larger context, even if each question costs more.

For inexpensive everyday requests, Grok 4.5 is the winner: it costs less, has the same median speed, and delivers quality that is high enough for drafts and simple explanations. But it cannot be called the best overall — in the QueryWise ranking, it trails GPT-5.6 Sol at 6.
