Previewing Ultrafast mode: GPT-5.6 Sol at up to 14X the speed
Which summary reads better? Pick one — models revealed after.Both summaries are AI-generated.
Summary A
GPT-5.6 Sol now runs up to 14 times faster with the new Ultrafast mode, generating 750 output tokens per second, which enables real-time applications and significantly reduces latency for production LLM and agent workloads.
Summary B
GPT-5.6 Sol now runs at up to 750 output tokens/second on a Cerebras-backed API tier—roughly 14x typical speeds—which collapses the latency floor for anything token-bound. This makes previously impractical patterns viable: multi-step agent loops, real-time streaming UX, and heavy reasoning chains where you were paying for wall-clock time on serial generation.
