Qwen3.8-Max vs Qwen3-Max

Qwen3.8-Max from Alibaba Qwen against Qwen3-Max from Alibaba Qwen — specification, price and every benchmark both makers have published, in one table.

At a glance

Benchmarks

Qwen3.8-Max leads

Qwen3.8-Max wins 1 of the 1 benchmarks both models report, Qwen3-Max wins 0, consistently. The average gap across shared tests is 7.2 points.

Price

Qwen3-Max is cheaper

On a 3:1 input-to-output mix, Qwen3-Max costs $2.40 per million tokens against $3.00 for Qwen3.8-Max — about 1.2× less. Remember that a reasoning model bills its thinking as output, so cost per answer can diverge much further than cost per token.

What actually differs

  • Qwen3.8-Max has open weights under Qwen3.8-Max License, so it can run on your own hardware with no per-token cost and no dependency on an API staying available. The other is API-only.
  • Qwen3.8-Max takes 1M tokens of context against 262K — 3.8× more room for long documents or a large codebase.

Where these numbers come from

Every score on this page is a published figure, taken from the model's own card, system card, technical report or release post, or from a public leaderboard. CorX Labs did not run these evaluations. Most are self-reported by the lab that built the model, which means they were produced under that lab's own choice of prompt, scaffold and number of attempts — so treat them as a starting point for a shortlist, not as a settled ranking.

A score someone other than the model's maker measured is marked Independent and names its measurer. Those are the stronger numbers on this page — an outside harness has no reason to flatter anyone — and there are not many of them.

Where a figure has not been published, the cell reads Not reported rather than an estimate. Nothing here is inferred, interpolated or guessed. Each model records the month its row was last checked. Full method and caveats.
