OpenAI Launches GPT-4.5 Exclusively for Pro Users Amid GPU Shortages

The new model emphasizes emotional intelligence and conversational fluency but faces criticism for high costs and limited availability.

GPT-4.5 is currently available only to ChatGPT Pro subscribers due to a shortage of GPUs, with broader access planned after infrastructure upgrades.
The model is designed to deliver more natural and intuitive conversations, with improvements in emotional intelligence and user intent understanding.
Critics have called GPT-4.5 underwhelming, citing its high cost, slower performance, and continued issues with hallucinations, despite improvements from prior versions.
OpenAI is addressing its GPU constraints by installing tens of thousands of GPUs next week and has plans for custom AI chip development by 2026.
The release comes as OpenAI faces increasing competition from rivals like Elon Musk's xAI and Meta, as well as ongoing tensions between Musk and OpenAI CEO Sam Altman.
