Google has revamped its AI Overviews feature after criticism about providing inaccurate responses to online searches. The feature, powered by Google's Gemini language model, aims to provide concise answers and links to external sites. However, critics argue it makes verifying information more challenging and has generated unreliable responses. To address concerns, Google has made technical improvements, limited user-generated content, and added quality protections for health content. Despite efforts, critics worry about the impact on revenue and the sustainability of the model, which relies on websites it's now competing with.
