On August 7, 2025, OpenAI released their newest model, GPT-5. The next day, several users complained in social media about the performance of the model, claiming it was underwhelming and was "dumber" than the previous model. Users also realised OpenAI's platform was most of the time setting the lowest-performance GPT-5 models and discovered they can make the platform to set the better-performance models by adding "think harder" in prompts. Sam Altman claimed that a "malfunction" of the autoswitcher was the reason behind GPT-5 performance.

===Age verification (2026)===

With a justification to "help teens have an age-appropriate experience on ChatGPT", the platform will be implementing globally an age verification system to detect if a user is over 18 to allow them to access to mature content. OpenAI will scan and analyze the user's account, their conversations and their behavior - including the times of a day they use ChatGPT - to estimate their age. If this system detects a user as underage, it will use third-party tools provided by [[Persona]] to estimate their age, asking the user to upload a selfie or their government ID. If the user refuses to send a selfie or their ID, the platform will limit ChatGPT's generated content.<ref>{{Cite web |date=21 Jan 2026 |title=Age prediction in ChatGPT |url=https://help.openai.com/en/articles/12652064-age-prediction-in-chatgpt |url-status=live |archive-url=http://web.archive.org/web/20260119032400/https://help.openai.com/en/articles/12652064-age-prediction-in-chatgpt |archive-date=19 Jan 2026|access-date=26 Jan 2026 |website=OpenAI}}</ref>
