OpenAI previews Ultrafast API tier powered by Cerebras running GPT-5.6 Sol at up to 14× speed
↗
OpenAI is previewing Ultrafast, a new API tier powered by Cerebras hardware that runs its GPT-5.6 Sol model up to 14× faster, generating up to 750 output tokens per second.
WHY IT MATTERS
A 14× inference speed increase on OpenAI's most capable model could reshape latency-sensitive applications like real-time agents, conversational interfaces, and interactive coding tools. The Cerebras partnership also signals OpenAI diversifying its inference hardware beyond traditional GPU providers.
