<p id="speakable-summary" class="wp-block-paragraph">If you’ve ever found yourself wishing that ChatGPT was a little bit quicker on the uptake, OpenAI seems to be answering your prayers. </p>
<p class="wp-block-paragraph">The AI lab has rolled out a new mode <a href="https://openai.com/index/previewing-ultrafast/" target="_blank" rel="noreferrer noopener nofollow">called Ultrafast</a>, which it says is designed to seriously accelerate the pace at which its latest and most powerful model, <a href="https://techcrunch.com/2026/07/09/openai-launches-its-new-family-of-models-with-gpt-5-6/">GPT-5.6 Sol</a>, accomplishes its work.</p>
<p class="wp-block-paragraph">The company says that Ultrafast can work at 14x the speed of standard processing, delivering up to 750 output tokens — such tokens represent the distinct pieces of text generated by an LLM when it interacts with a human — per second. </p>
<p class="wp-block-paragraph">“Until now, getting real-time speed typically meant choosing a smaller or more specialized model,” the company said <a href="https://openai.com/index/previewing-ultrafast/" target="_blank" rel="noreferrer noopener nofollow">in the blog post</a> on Thursday. “Ultrafast points to progress in a new direction: more useful work per second.”</p>
<p class="wp-block-paragraph">OpenAI’s competitors, like Anthropic, have similarly launched accelerated versions of their models. <a href="https://platform.claude.com/docs/en/build-with-claude/fast-mode" target="_blank" rel="noreferrer noopener nofollow">Claude has fast mode</a>, although it doesn’t deliver the kind of speed that OpenAI is offering here.</p>
<p class="wp-block-paragraph">OpenAI suggests that this high-octane version of GPT-5.6 Sol can be deployed across a number of different corporate workflows, most notably incident response, customer service and support, financial market analysis, and e-commerce, among other relevant areas.</p>
<p class="wp-block-paragraph">Ultrafast, which is currently being released in preview, is being powered by OpenAI’s partnership with chipmaker Cerebras. Currently, that preview is only being made available to a small group of customers, although OpenAI says that it will expand access to the feature as “capacity grows.” </p>
