Qwen 3.8 27B scores 52 on the Artificial Analysis Intelligence Index

An open-weight 27B model scoring level with a frontier closed model on a public index changes the arithmetic on running inference locally instead of paying per token.

• open weights — A model whose trained parameters are published for anyone to download and run — unlike API-only models you can access but never possess.
• inference — Running a trained model to get answers — the phase where AI is actually used, as opposed to trained.
• token — The chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.
