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.

A new model labeled "GPT-5 Mini Scout" briefly appeared in ChatGPT's model selector, sparking speculation about its connection to a new Company Knowledge feature for enterprise users. An update in OpenAI’s JavaScript library hinted at the model being named "GPT-5.1 Mini," suggesting significant advancements in image generation capabilities. The potential rollout for this model is anticipated in November, possibly in response to competitors like Google's Gemini 3.

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.

Users of OpenAI's ChatGPT are expressing their disappointment and mourning over the perceived delayed release of GPT-5, with many taking to social media to share their frustrations and hopes for the new version's capabilities. The anticipation for improvements in the AI's performance and features has created a buzz in the online community, highlighting the significant impact these models have on user experience.
