Running on Cerebras wafer-scale silicon instead of standard GPU infrastructure, GPT-5.6 Sol on Ultrafast generates up to 750 output tokens per second, roughly 14 times the ~53 tokens per second the standard tier delivers. That is the difference between a model that streams an answer while you wait and a model that finishes before you have registered it started.</p>
