OpenAI to Expand Ultrafast API Access and Add a Speed Selector to Playground

OpenAI is preparing to widen access to Ultrafast, its Cerebras-powered API tier that runs GPT-5.6 Sol up to 14 times faster than Standard, and its Playground code now holds a hidden Standard, Fast and Ultrafast speed selector. We checked the code and the API specification ourselves. This article explains how the tiers fit together, what 750 tokens per second means, what is known about price and model support, where the speed pays off and how to prepare before DevDay.

Crusoe Raises $3.9B to Build Massive Data Centers and Small Modular ‘AI Factories’

Crusoe announced the initial closing of a $3.9 billion Series F at a $30.9 billion valuation on 17 September 2026, co-led by Atreides, Mubadala Capital and Valor. The money funds both Abilene-scale campuses and Spark, modular data centers built in Crusoe’s own factories and trucked to available power. We work through the numbers (a $27.0 billion pre-money, a 3.09-fold jump in ten months, one gigawatt running of six contracted), the new directors that point to an IPO, and three claims buyers should read carefully.

The Information reported on 16 September 2026 that Apple is developing an enterprise AI server built around future M8 Ultra silicon, in two- and four-chip configurations, and has discussed using Nvidia’s NVLink Fusion interconnect to wire them together. Nothing is finalised, nothing ships before 2029, and the project could be cancelled. This article separates the single-sourced claims from the confirmed facts: Apple’s Houston plant has been shipping Private Cloud Compute servers since October 2025, the shipping M5 Ultra runs at 1.2TB/s of unified memory bandwidth, and Apple’s roughly $13 billion of annual capex sits against $725 billion of combined 2026 guidance from four rivals.
