## GPT-5.6 Sol is both better and cheaper.

It scores **+12.5** higher and costs **33% less** ($4.00/M against $6.00/M) on this workload — and it does everything this model does.

[GLM 5.3](/models/z-ai__glm-5.3) is cheaper still (64% less) but drops no image, file input.

The same model via **batch** is 50% cheaper ($3.00/M) — same weights, different latency.

Sources are listed separately rather than averaged. Across the 62 models both have scored they correlate at r = 0.806 — close agreement overall, but four models rank very differently between them, and a blended score would hide exactly those.
