OpenAI Rolls Out GPT-4.5 to ChatGPT Plus Subscribers in Stages

The staggered release aims to manage demand for the new AI model, which features enhanced emotional intelligence and reduced hallucinations.

OpenAI has begun a gradual rollout of GPT-4.5 to ChatGPT Plus subscribers, following its earlier release to Pro users last week.
CEO Sam Altman cited server capacity challenges and a lack of GPUs as reasons for the staggered release instead of a simultaneous launch.
GPT-4.5 introduces improved emotional intelligence, a broader knowledge base, and fewer hallucinations, but it is not considered a reasoning model.
The model's high operational costs have led OpenAI to consider changes to its pricing structure, including a potential token-based system for users.
While GPT-4.5 boasts advancements, it falls short on some AI benchmarks compared to newer reasoning models from competitors.
