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

It scores **+3.6** higher and costs **60% less** ($4.00/M against $10.00/M) on this workload — and it does everything this model does.

[Grok 4.6](/models/x-ai__grok-4.6) is cheaper still (70% less) but drops 1.0M → 500K context.

The same model via **batch** is 50% cheaper ($5.00/M) — same weights, different latency.
