Qwen3.8-27B — a Pro model that costs a quarter of a request

August 16, 2026

Qwen3.8-27B is live on Pro plans at 0.25× quota — four requests for the price of one.

It handles a 250K-token context, supports tool calling, and thinks step by step before answering (reasoning is returned separately, so you can show or hide it). Released by Alibaba on 14 August 2026.

Call it as Qwen3.8-27B from any client.

One note if you use it programmatically: thinking is on by default and consumes part of your max_tokens budget. Give it room — a few thousand tokens — or turn thinking off if you only want the answer.
