OpenAI Expands GPT-4.5 Access to ChatGPT Plus Users

The advanced AI model promises improved accuracy, reasoning, and conversational capabilities, now available at a lower price tier.

OpenAI has completed the rollout of GPT-4.5 for ChatGPT Plus subscribers, priced at $20 per month, following its earlier launch for ChatGPT Pro users at $200 per month.
The new model offers enhanced contextual understanding, reduced hallucinations, and improved alignment with user prompts for more intuitive interactions.
GPT-4.5 outperforms its predecessor, GPT-4o, and other models in key benchmarks, including multilingual tasks and coding evaluations.
CEO Sam Altman proposed a potential credit-based payment system for ChatGPT users, sparking mixed reactions on social media.
The staggered release of GPT-4.5 was intended to ensure stable performance and avoid server overload during the rollout process.
