Qwen4-Max Benchmarks: What Scores Exist So Far — and Which Numbers Are Rumors

Published Nov 13, 2026 · Last updated Nov 13, 2026

Anyone searching "Qwen 4 Max benchmark" wants a straight answer, so here it is up front: as of November 13, 2026, Alibaba has published no official benchmark scores for Qwen4-Max-Preview and no model card, and third-party leaderboards such as Artificial Analysis and LMArena have not listed it. What exists is one independent measurement, a roundup of hands-on tests, and a few rumored numbers to be wary of. This article inventories all three, separately.

What actually exists

StealthMark's first independent run (Stealth Models, Nov 11–12): visual intelligence above Qwen3.8-Max, general intelligence below it, with the two game tasks falling most. These are editorial estimates on a small sample — a directional signal, not a formal score. See our read on the first independent run.

AI First Look's 8-test roundup (Nov 12): 4 positive, 4 mixed, 0 negative. The most informative data point is a coding task passed 20/20, same as Qwen3.8-Max, in about 2.5 minutes instead of 17; a T-Rex game test finished faster than Claude Fable 5.2 and Gemini 4 Carbon, though the tester still rated Fable 5.2 best overall. See our 8-test roundup review.

A speed anecdote: about 33 tokens per second, from a single hands-on measurement, unverified.

Why the rumored numbers can't be trusted

The "AA index 53" chart: circulating on social media with no primary source; Artificial Analysis has no Qwen4-Max entry to check it against.

"Qwen4-Coder at 82% on SWE-bench": likewise sourceless — and the Qwen4-Coder model itself is unconfirmed to exist.

A rule of thumb: with no public API during the preview, there are no reproducible test conditions. Any benchmark precise to the single digit is suspect until GA and official evaluations arrive.

Why there are no benchmarks yet

Three reasons. First, the preview lasts only two weeks (Nov 11–25), and vendors usually publish evaluations at GA. Second, Token Plan is subscription-only and its terms bar automation and batch jobs, which makes large-scale third-party testing hard. Third, leaderboards need a stable API and enough samples — the preview's access terms don't provide them.

What to watch next

Around the November 25 preview end, watch for three things: whether a GA release comes with official evaluations; whether Artificial Analysis and LMArena list Qwen4-Max; and whether it follows the Qwen3.8-Max precedent, which went preview → GA → open weights in about three weeks. When new scores appear, we will update this article and the topic page.

Our take: any ranking of Qwen4-Max right now rests on nothing. The only reliable evaluation is to run your own real tasks on it before November 25 and archive the results.
