Salesforce CEO Marc Benioff, one of Silicon Valley’s most vocal boosters of ChatGPT, announced Sunday that he’s abandoning OpenAI’s chatbot after a brief trial of Google’s newly released Gemini 3 model.
“Holy s—. I’ve used ChatGPT every day for 3 years. Just spent 2 hours on Gemini 3. I’m not going back,” Benioff wrote on X. “The leap is insane — reasoning, speed, images, video… everything is sharper and faster. It feels like the world just changed, again.”
Benioff, who has 1.1 million followers on X, had more than 3.2 million people see his post by Tuesday morning, according to the social network. His endorsement is notable not just because of his prominence—his net worth is currently around $8.5 billion, according to Forbes—but because of his company’s extensive partnerships across the AI landscape. Just last month, Salesforce announced an expanded strategic partnership with OpenAI, integrating its Agentforce 360 platform with ChatGPT and allowing enterprises to use OpenAI’s GPT-5 models within Salesforce products.
At the time, Benioff praised that collaboration. “As consumers, we already get instant recommendations or insights from ChatGPT,” he said in October. “Now enterprises can deliver that same intelligence and immediacy.”
