acknowledged that Astra can consume usage allowances faster than its predecessor GPT 5.6 Sol, requiring substantially more computing resources per user session.

systems, a 6-GW Advanced Micro Devices agreement for GPUs, and a Broadcom partnership deploying 10 GW of custom AI accelerators. These investments reflect the delicate balance AI companies must strike between model capability and infrastructure economics, particularly as concerns emerge about potential oversupply if the AI market cools.

What This Means for AI Competition and Users

The capacity crunch highlights a fundamental shift in AI competition. Success now depends not only on developing intelligent models but also on scaling the underlying infrastructure to deliver those capabilities to millions of users simultaneously. As AI systems like Astra perform increasingly complex computer-based tasks autonomously, the computing resources required per user session multiply. Watch for how quickly 5

restores Pro tier availability—this timeline will signal whether the company's infrastructure expansion plans can keep pace with user adoption. For prospective users, the Plus tier remains available and provides access to Astra, though with more limited usage compared to the Pro plan's 20x capacity. The situation also raises questions about whether competitors face similar infrastructure constraints or have built sufficient headroom to capitalize on OpenAI's temporary capacity limitations.
