OpenAI pauses new $200 ChatGPT Pro sign-ups as Astra demand strains capacity · Chronopin

OpenAI announced on Thursday that it is "pausing new sign-ups and upgrades to the most expensive plan on the Pro tier", the $200-per-month ChatGPT Pro plan that provides 20 times the usage of Plus and is where its new Astra model is available; existing Pro accounts are unaffected.^[1][2] The Next Web names the tier Pro 20X and adds that the $100 Pro plan, Plus, Go, the API and enterprise accounts remain on sale.^[3]
The cause is demand for Astra outrunning compute. Head of product Thibault Sottiaux said on X that the $200 plan "puts the most strain on the AI lab's systems": "We wanted to take the smallest step that allows us to continue giving the broadest access possible", adding that OpenAI is "working on adding more capacity".^[1][2][3]
A day earlier Sottiaux had called demand for Astra "unprecedented" and warned OpenAI "might have to pause new Pro subscriptions for a bit": "We're pulling all the levers possible to sustain the demand, but I've not seen anything like it until now and we went through very steep growth before."^[1][2]
Astra launched "last week" relative to the September 11, 2026 reports, initially open only to a handful of enterprise customers to give OpenAI time to scale compute; president Greg Brockman called it the start of the "AGI era".^[1][2] The Next Web dates the launch more precisely to 3 September.^[3]
Astra's marquee feature, "computer use", "allows it to interact with a desktop the way a human would, like filling out forms and navigating web pages at 'superhuman speed'" per Brockman, and OpenAI said Astra "can burn through users' usage allowances faster than its previous flagship model GPT 5.6 Sol".^[1][2]
OpenAI gave no reopening date and says it is adding capacity as fast as it can.^[3] It had also paused Astra in August for a different reason - it could not rule out critical cyber capability - which was safety rather than supply.^[3]
Precedent: in November 2023 OpenAI temporarily halted sign-ups to the $20-per-month ChatGPT Plus plan after its first developer conference, with Sam Altman writing "The surge in usage post devday has exceeded our capacity and we want to make sure everyone has a great experience."^[1][2]
On capacity, OpenAI said available compute rose from 0.2 gigawatts in 2023 to about 1.9 GW in 2025, a 9.5-fold increase.^[1][2] Fortune adds that OpenAI has gone beyond Microsoft Azure to CoreWeave and launched Stargate (a $500 billion, four-year buildout), with new capacity from the second half of 2026 including at least 10 GW of Nvidia systems, a 6-GW AMD agreement and a 10 GW Broadcom custom accelerator partnership; OpenAI did not respond to Fortune's request for comment.^[2]
For European buyers, Microsoft Foundry lists Astra across 26 regions but all six data zone deployments are American - France Central and Germany West Central carry it only as a global deployment - so no paid option keeps processing inside the EU data boundary; ENISA received access about a week after launch and is testing Astra alongside Anthropic's Mythos 5.^[3]
