A What it is for

Note it ships under a custom licence, NOT Apache 2.0; the hosted qwen3.8-max adds vision, non-thinking mode and 1M context by default.

At a three-to-one input-to-output ratio, Qwen3.8-2.4T-A95B costs $3.00 per million tokens blended. A workload of one million input and 330,000 output tokens per day would run about $119.40 per month at list price, before caching or batch discounts.
