When to use Qwen3.8-27B Flash

Single-turn production chat where 32,768 tokens of context is enough — pair it with retrieval instead of stuffing whole documents into the prompt.

An open-weights base you can also self-host: the weights serving this id are published at Qwen/Qwen3.8-27B.

Budget from $0.40/M input, $0.040/M cached input, $1.60/M output — no benchmark or output-speed figure is published for this id in our catalog, so measure latency on your own traffic before committing volume.

What it costs

Worked example on the rates above: 1,000,000 input tokens plus 200,000 output tokens, billed per 1M.

Component	Tokens	Rate / 1M	Cost
Input (uncached)	1,000,000	$0.40	$0.40
Input (cached)	1,000,000	$0.040	$0.04
Output	200,000	$1.60	$0.32
Total	1,200,000	—	$0.72

With the same 1,000,000 input tokens served from cache ($0.040/M) the call costs $0.36 instead of $0.72 — cached prefixes are the lever on repeat traffic.
