Qwen3 Next 80B A3B Thinking comes from Qwen (Alibaba); in uttapen you reach it with the model id "qwen/qwen3-next-80b-a3b-thinking". It accepts up to 262,144 tokens of input per call, so a long document or several source files fit in a single request. A single response can run to 235,929 tokens. On price it sits in the "cheap" band — cheaper than 151 and dearer than 255 of the other paid models in the catalogue.
What you get on top of text in, text out: it supports tool calling, so it can invoke your own functions with valid arguments; it returns schema-valid JSON through response_format, ready to hand to your code; it has a reasoning mode that pays off on multi-step problems, maths and debugging. All of it works through the standard parameters of the official OpenAI SDK — no custom client, no wrapper. Keep in mind that reasoning tokens are output tokens and do appear on the bill.
Input runs at 43,519 toman per 1M tokens and output at 348,150 — output costs 8× input, so trimming the answer saves more than trimming the prompt. You are always charged for the usage the request actually reported, never for the estimate, and a failed request costs nothing.
The closest alternative with the same capabilities from a different provider is KAT-Coder-Pro V2: Qwen3 Next 80B A3B Thinking works out roughly 1.1× cheaper, and its context window is the same size. Both run on the same key and the same code, so trying the other one is a single string change.
To make the figure concrete: 100,000 toman of credit buys roughly 196 thousand-word requests on Qwen3 Next 80B A3B Thinking, and every 1,000 toman is about 1,965 words of round trip. A job with one million input tokens and one million output tokens comes to 391,669 toman in total. Filling this model's 262,144-token window costs 11,408 toman on the input side alone, which is the real reason to keep conversation history short.
Its nearest relative in the catalogue is "qwen/qwen3-30b-a3b", and choosing between those two is where most people hesitate. On a thousand-word request this variant works out 2.2× dearer (509 against 234 toman). The context windows differ too: 262,144 against 131,072 tokens. Maximum answer length differs as well: 235,929 against 16,384 tokens. On parameters, this one takes logprobs, structured_outputs, top_logprobs while the other takes logit_bias, min_p.
Qwen (Alibaba) has 53 models in our catalogue; the cheapest is Qwen3.7 Flash at 60 toman per thousand words and the dearest Qwen3.8 Max (0902) at 3,017. Among the less common parameters it accepts logprobs, repetition_penalty, top_k, top_logprobs — all through the standard request body. By context size the nearest option from another provider is Trinity Large Thinking at 262,144 tokens.
Where it makes sense: high-volume work such as classification, tagging and bulk summarising, logic puzzles and code review, agents that reach out to APIs and databases, extracting data against a fixed schema, analysing a long document or codebase in one request.
Qwen3-Next-80B-A3B-Thinking is a reasoning-first chat model in the Qwen3-Next line that outputs structured “thinking” traces by default. It’s designed for hard multi-step problems; math proofs, code synthesis/debugging, logic, and agentic...
