OpenAI introduces ‘Ultrafast,’ a new mode that makes GPT-5.6 Sol work at 14x the speed
OpenAI has unveiled 'Ultrafast,' a preview mode designed to make its upcoming GPT-5.6 model run at 14 times the speed of standard versions, targeting enterprise users who require low-latency AI responses. The feature aims to enhance performance in real-time applications such as customer service, trading systems, and industrial automation. By prioritizing speed without fully disclosing trade-offs in accuracy or cost, OpenAI is positioning Ultrafast as a competitive differentiator in the rapidly evolving enterprise AI landscape.
What this means for you
Businesses evaluating AI for latency-sensitive use cases should test Ultrafast’s performance and accuracy trade-offs before integrating it into mission-critical workflows.

Anthropic CEO says it’s time to pump the brakes on AI
Anthropic CEO Dario Amodei has proposed a strategic shift in AI development, advocating for a measured pace rather than an unchecked race for intelligence. By inviting independent third-party assessors like METR to audit their systems, the company aims to establish a new standard for transparency and safety. This move signals a significant departure from the 'growth-at-all-costs' mentality, suggesting that the industry must prioritize verifiable safety protocols before deploying more powerful models to the public.

Anthropic CEO Dario Amodei has proposed a strategic shift aimed at decelerating the breakneck speed of artificial intelligence development. By advocating for a more deliberate 'pacing' of innovation, the company suggests that industry leaders should prioritize safety evaluations and societal impact assessments over mere technical capability benchmarks. This shift marks a significant departure from the competitive race between major AI labs, highlighting growing concerns that rapid deployment without adequate guardrails could pose existential or systemic risks to global infrastructure.

Y Combinator leader Garry Tan is advocating for a shift in how leading artificial intelligence developers share their technology. He contends that since foundational models are built upon vast repositories of human-generated information, the resulting capabilities should be accessible as a public benefit. By encouraging labs to create smaller, distilled versions of frontier models, Tan hopes to democratize access to high-performance AI, moving away from closed-off ecosystems toward a more equitable distribution of innovative tools.
