What is Qwen3.8 2.4T A95B good for?

Qwen3.8 2.4T A95B comes from Qwen (Alibaba); in uttapen you reach it with the model id "qwen/qwen3.8-2.4t-a95b". It accepts up to 1,048,576 tokens of input per call, so a long document or several source files fit in a single request. A single response can run to 131,072 tokens. On price it sits in the "mid-range" band — cheaper than 92 and dearer than 290 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 692,439 toman per 1M tokens and output at 2,077,316 — output costs 3× input, so trimming the answer saves more than trimming the prompt. It supports cached input: repeated context is billed at 86,555 toman per 1M, which matters a lot if your system prompt is long. 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 Aion-3.0: Qwen3.8 2.4T A95B works out about 9% cheaper, and its context window is larger. 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 28 thousand-word requests on Qwen3.8 2.4T A95B, and every 1,000 toman is about 278 words of round trip. A job with one million input tokens and one million output tokens comes to 2,769,755 toman in total. Filling this model's 1,048,576-token window costs 726,075 toman on the input side alone, which is the real reason to keep conversation history short.

Its nearest relative in the catalogue is "qwen/qwen3.7-max", and choosing between those two is where most people hesitate. On a thousand-word request this variant works out about 40% more expensive (3,601 against 2,656 toman). The context windows differ too: 1,048,576 against 1,000,000 tokens. On parameters, this one takes reasoning_effort, repetition_penalty.

Qwen (Alibaba) has 42 models in our catalogue; the cheapest is Qwen3.7 Flash at 72 toman per thousand words and the dearest Qwen3.8 Max Prime at 7,201. Among the less common parameters it accepts logprobs, presence_penalty, reasoning_effort, repetition_penalty, top_k, top_logprobs — all through the standard request body. By context size the nearest option from another provider is DeepSeek V4 Flash 0423 at 1,048,576 tokens.

Where it makes sense: product chatbots and internal assistants, where cost and quality have to balance, 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.
