'The world just changed...', says Salesforce CEO Marc Benioff after ditching ChatGPT for Google Gemini

Salesforce CEO Marc Benioff has set the internet buzzing after posting a bold endorsement of Google’s newly released Gemini 3 model. In a tweet that has quickly gone viral, the Salesforce CEO said he had spent two hours testing the upgraded system and was convinced it represented a major leap in artificial intelligence. According to him, it is such a significant improvement that he will no longer rely on ChatGPT, a tool he says he has used daily for the past three years.

Benioff described Gemini 3 as “insane” in terms of reasoning, speed and multimodal performance. He highlighted that image and video understanding felt sharper and faster, adding that it gave him the sense that “the world just changed, again”. Coming from one of the most influential voices in enterprise software, the remark has only intensified the ongoing conversation around the rapid pace of AI development.

Google is positioning Gemini 3 as its most advanced model yet and a direct competitor to OpenAI’s top-tier systems. Early testers have shared mixed but largely positive impressions, particularly around its performance in complex reasoning tasks and its responsiveness in handling images and long-form content. Benioff’s endorsement, however, is easily the most high-profile reaction so far.

His comments have also reignited the rivalry narrative between Google and OpenAI, at a time when the AI industry is evolving at breakneck speed. Developers, creators and businesses are watching closely, given how quickly model capabilities now influence productivity workflows and software choices. If more high-profile users mirror Benioff’s sentiment, it could shift momentum in Google’s favour.
