GPT-OSS 120B vs GPT-6 Astra — which is better?

Quality: the gap is too wide for a tie

At the time of this page’s update, GPT-OSS 120B scores 3.7 out of 10 and ranks 35 in QueryWise. GPT-6 Astra scores 9.3 out of 10 and holds 4. GPT-6 Astra is currently ahead on score. This is not a case where a few tenths decide the outcome: the models are designed for different levels of workload.

GPT-OSS 120B has an interesting imbalance. It scores 9.9 for reasoning and 5.0 for coding. That is a solid result for unpacking a complicated requirement, but its score is noticeably more modest when writing and fixing code. GPT-6 Astra scores 9.5 for coding; its reasoning result is not published in the current QueryWise dataset, so assigning it a specific number would be misleading.

We ran both models through real-world questions. Asked to “find the bug in a Python function that calculates VAT and explain the result using a price in tenge,” GPT-6 Astra maintains the structure confidently: it identifies the defect, provides a corrected version, and includes a verification example. GPT-OSS 120B handles the logic of the requirement well, but its programming answers more often need an additional review. That is acceptable for analytical work. For code that needs to run today, it is not.

Price and speed: a cheaper model does not always save time

In QueryWise, the average cost of a question is approximately 10 ₸ for GPT-OSS 120B and about 43 ₸ for GPT-6 Astra. Across ten identical queries, the difference adds up quickly. If you ask a model every day to rephrase emails or explain terms briefly, GPT-OSS 120B is gentler on the budget.

But the price of an answer is not the same as the cost of the result. When a task involves several files, code, or lengthy constraints, a more expensive GPT-6 Astra query may pay for itself by requiring fewer follow-up clarifications. In QueryWise, both models are billed in tenge, work with Russian- and Kazakh-language interfaces, and new users receive three free questions to get started.

So it is not currently possible to call either model faster. We will not turn missing telemetry into a polished but invented conclusion.

Context and tasks: where each model fits best

GPT-6 Astra works with a context of 1.1M, while GPT-OSS 120B offers 131K. In practice, that changes the workflow. If you need to review a long contract in one query, compare several sections of a technical specification, or track changes across a large project, Astra’s additional capacity is noticeably more convenient.

GPT-OSS 120B is a sensible choice for short and medium-sized tasks where price is the deciding factor. For example, it works well when you need to review several possible replies to a customer in one evening, check the logic of a mathematical solution, or get a complex topic explained in plain language. Its strong reasoning may be more useful than a difference in interface.

GPT-6 Astra is preferable in three specific situations: debugging several related files, turning extensive material into a single plan, or preparing a working draft with many conditions. For coding, its 9.5 versus 5.0 for GPT-OSS 120B makes a more convincing case than any broad promise.

In QueryWise, you can ask both models the same question and see where they agree and where they diverge. That is useful for contentious analysis: GPT-OSS 120B can sometimes provide a strong logical framework, while GPT-6 Astra turns it into a more complete and practical answer.

An honest verdict

For coding, long documents, and tasks where a ready-to-use result matters on the first pass, choose GPT-6 Astra. It leads on the current score, and its coding advantage is especially clear.

Choose GPT-OSS 120B when your budget is limited, the question does not require a huge context window, and you are willing to review the code or ask for a second pass. At approximately 10 ₸ per average query versus 43 ₸ for GPT-6 Astra, it is a rational option for frequent short requests.

The final choice depends on the scenario, not on diplomacy: GPT-6 Astra is stronger as an all-purpose working model, while GPT-OSS 120B is more interesting as an affordable assistant with strong reasoning. Both are available in QueryWise from Kazakhstan. They are assistants, not substitutes for medical, legal, or financial advice.
