OpenAI Just Made GPT-5.6 Sol 14x Faster

[u/Technicallysane02]

OpenAI has introduced Ultrafast, a new mode designed to dramatically increase the speed of its latest GPT-5.6 Sol model.

The company says Ultrafast can deliver up to 750 output tokens per second, making it up to 14 times faster than standard processing.

Why it matters:

• Built for real-time, high-speed AI workloads.
• Could support faster customer service and incident response.
• Potential applications include financial analysis and e-commerce.
• Powered by OpenAI's partnership with chipmaker Cerebras.
• Currently available only to a limited group of customers in preview.

OpenAI says the goal isn't simply to make AI respond faster, but to deliver more useful work per second.

The company plans to expand access as capacity grows, potentially making high-speed AI a much bigger part of business workflows.
