Existing Pro subscribers ($200-a-month) remain prioritized, while Go, Plus and API access continue to accept new customers. Launched on September 3, Astra has generated what OpenAI describes as “unprecedented” demand. The company has not said how long the pause will last or how many new Pro subscriptions it had been adding before the change.

Founder of Stack Chronicle and a journalist with experience across several local and national radio stations (including RTL2, Hit West, Euradio and Figaro Radio in France, and WDET in Detroit, Michigan), I began taking a deeper interest in technology in the wake of the COVID-19 pandemic. I quickly realised, that few media outlets were building meaningful connections between technology, AI, finance, politics and environmental issues. That observation led to the creation of Stack Chronicle: a publication designed to help both curious readers and more informed audiences understand the technological transformations shaping our world.
