How much energy does Qwen3-235B-A22B-Thinking (Jul 2025) use?

Alibaba · released 2025-07-25

Qwen3-235B-A22B-Thinking (Jul 2025) uses about 0.059 Wh – 1.23 Wh of electricity to answer a typical question. That places it 189 of 266 among the models we can measure, and every figure here is calculated the same way as every other model.

How capable is it, really?

The capability figure of 143.88 is a composite over 58 benchmarks — Epoch AI's Capabilities Index, which folds in software engineering, agentic tool use, long-context comprehension and creative writing as well as science reasoning. It is one number standing for a lot of separate tests, so treat a small gap between two models as noise rather than a ranking.

No human head-to-head votes exist for this model. It has been benchmarked but not, as far as we can tell, put in front of people to compare against anything else — worth knowing before treating its scores as a verdict on its answers.

What this figure is

Inferred  The maker publishes no size at all, so it is inferred from how capable the model is and when it was released. A wide bracket, not a figure. Every model on this site is calculated the same way, so the comparison holds even where the absolute value carries uncertainty. Our figures are good to roughly a factor of two to three, which is why we only ever state a difference of 5× or more.

We cannot pin this one down. Alibaba has never published how Qwen3-235B-A22B-Thinking (Jul 2025) is built, and the two plausible answers are far apart — which is why a range is shown rather than a figure. It is listed because leaving it out would reward the silence, and it is barred from every headline claim on this site.

Is there a better choice?

A lighter model that does the job
Alibaba · capability 146.5. It scores higher than Qwen3-235B-A22B-Thinking (Jul 2025) on Epoch's Capabilities Index (146.49 against 143.88), the composite over 58 benchmarks that the capability figure above comes from, and uses about 18× less energy per answer: 0.351 Wh against 6.29 Wh.

What Alibaba publishes

Energy cannot be worked out without knowing how big a model is. Of the 45 models from Alibaba that we track, 25 can be assessed at all — the rest publish too little for anyone outside the company to calculate anything.

Where these figures come from

Capability and the roster come from Epoch AI, whose Capabilities Index is the 58-benchmark composite quoted above. Energy is calculated with EcoLogits and calibrated against laboratory measurements from ML.ENERGY. Human preference comes from LMArena. All four are public and free; the full method is here.
