web3: OpenAI Launches Ultrafast Mode, GPT 5.6 Sol Speed Increased to 14 Times

CoinWorld reports:

OpenAI has launched a new mode called Ultrafast, which focuses on higher model response speeds. The company claims that this mode allows GPT 5.6 Sol to run at 14 times the standard processing speed, with output speeds reaching up to 750 tokens per second, currently available in preview form to a limited number of customers.

This update targets the demand from enterprises for real-time AI processing. OpenAI states that in the past, to achieve responses closer to real-time, it was often necessary to switch to smaller models or choose systems optimized for specific tasks. The direction of Ultrafast is to increase the effective workload that can be completed in a given time without solely relying on smaller models.

Increased Output Speed

According to OpenAI, the core selling point of Ultrafast is significantly reducing generation wait times.

• Maximum output speed can reach 750 tokens per second
• Processing speed is about 14 times that of the standard mode
• The current version is still in the preview stage

TechCrunch mentions that competitors like Anthropic have also previously launched acceleration modes. For example, Claude offers a fast mode as well, but the speed metrics announced by OpenAI this time are higher.

Targeting Enterprise Workflows

OpenAI has directed the application scenarios of Ultrafast towards various enterprise tasks, focusing on event response, customer service and support, financial market analysis, and e-commerce operations. These scenarios are typically more sensitive to delays, and the model's response time directly affects the efficiency of human collaboration and the performance of automated processes.

From a product positioning perspective, Ultrafast is not a standalone new model but rather a high-speed operating method provided around GPT 5.6 Sol. For enterprise customers, this means attempting to integrate AI more directly into real-time business processes while retaining strong model capabilities.

Supported by Cerebras

OpenAI states that Ultrafast is supported by its collaboration with chip company Cerebras. The first batch of preview qualifications is currently only open to a small number of customers, with plans to gradually expand access as computational capacity increases.

This also indicates that the competition among large models is extending from parameters and capabilities to response speed, deployment efficiency, and underlying computational synergy. For AI products aimed at the enterprise market, speed is becoming a key metric alongside model quality.
