Overview
What is Qwen 3.8 Flash?
Qwen 3.8 Flash is Alibaba's fast, low-cost Qwen 3.8 model, a 125B-parameter mixture-of-experts with only 6B active per token and a 1M-token context window. The zurelay Qwen 3.8 Flash API serves it through one OpenAI-compatible endpoint at 53% below Alibaba's international list price, for coding helpers, agents and high-volume pipelines.
Alibaba released Qwen 3.8 Flash on August 26, 2026 as the fast, low-cost model of the Qwen 3.8 family. It is the open-weight Flash-Next model: a mixture-of-experts with 125B total parameters and just 6B active per token, which previews the Qwen4 architecture. The small active size is what keeps it quick and cheap to run.
The Qwen 3.8 Flash API reads text, images and video and writes text, with a 1M-token context window and up to 131,072 output tokens per response. Alibaba points to coding help, agent workflows and visual understanding, with examples such as fixing code on its own, operating desktop applications and analyzing charts and long videos.
It supports a thinking mode, function calling, structured outputs and context caching. Alibaba charges one rate at every prompt length, up to the full 1M tokens.
On zurelay the model ID is qwen3.8-flash, and qwen/qwen3.8-flash and qwen-3-8-flash work as aliases. You pay $0.07 per 1M input tokens and $0.22 per 1M output tokens, against Alibaba's international list price of $0.15 and $0.47.

Streaming works with stream: true, as with the OpenAI API. You can set a requests-per-minute cap and a monthly budget on each zurelay API key. Failed attempts are retried automatically and never billed.
Is it the same Qwen 3.8 Flash model Alibaba serves?
Yes. Requests go to Qwen 3.8 Flash, never a smaller or substitute model. Responses are sampled, so wording varies between runs, as it does on Alibaba's own API. zurelay is independent and not affiliated with Alibaba Cloud.
