Speed is the constraint. 47 tok/s is slow for a chat UI.

Capable, not fast. The API is closed even though Qwen is known for open releases.

  • AA Index. The single number most people mean by “how smart.” It is a blend, so a specialist can lose here and still win the job you care about.
  • GPQA. A clean test of hard reasoning. PhD experts sit around 65%. It says little about writing, tools, or taste.
  • Term.. Closest public proxy for coding agents that live in a terminal. A high index score with a weak terminal score is a warning.
  • Arena. Captures taste and usefulness that unit tests miss. Sample size varies by model, so treat gaps under ~100 Elo as noise.

Qwen · Hangzhou. Two flagships: Qwen3.8-Max is a proprietary multimodal API. The 2.4T checkpoint is downloadable, text-only, and commercially restricted.

Compiled 2026-08-28 from public Artificial Analysis, LMSYS-style arena, and first-party price sheets. Scores move. Recheck before you spend.

A two-point gap on the intelligence index is noise for most work. Cost per finished task is the number that shows up on the invoice.
