OpenAI has launched GPT-5 along with three variants—GPT-5 Pro, GPT-5 mini, and GPT-5 nano—now accessible to all ChatGPT users, including free tiers. The new model boasts improved coding capabilities, reduced confabulations, and a novel approach to handling sensitive requests, while also introducing simulated reasoning for better accuracy in complex queries. Although the advancements are notable, some perceive GPT-5 as an incremental upgrade compared to previous models in the series.

OpenAI is considering reintroducing the older ChatGPT model 4o for Plus subscribers after user backlash against the newly released GPT-5 model, which many found less friendly and conversational. CEO Sam Altman acknowledged the feedback during a Reddit AMA and noted the rollout of GPT-5 faced unexpected issues.
