Salesforce CEO Marc Benioff has declared that Google’s latest AI model, Gemini 3, is so advanced he has stopped using OpenAI’s ChatGPT altogether. In a viral post on X, Benioff described the leap in performance as “insane,” writing, “Holy shit. I’ve used ChatGPT every day for 3 years. Just spent 2 hours on Gemini 3. I’m not going back. The leap is insane — reasoning, speed, images, video… everything is sharper and faster. It feels like the world just changed, again.” The post quickly gained traction, amassing over a million views within hours of being published. Benioff’s endorsement adds to a growing wave of high-profile praise for Google’s newest AI model, which has been lauded for its enhanced reasoning, multimodal capabilities, and speed. Other tech leaders have echoed Benioff’s enthusiasm. Sam Altman, CEO of OpenAI, congratulated Google on the launch, calling the model “a great one” in a post on X. Former Tesla AI director Andrej Karpathy shared a positive early impression, describing Gemini 3 as a “very solid daily driver potential” and “clearly a tier 1 LLM.” Stripe CEO Patrick Collison also chimed in, highlighting how the model built an interactive web page summarizing 10 breakthroughs in genetics — a feat he called “pretty cool.” Gemini 3 was unveiled last week by Google and its DeepMind division, positioned as the company’s most powerful agentic and “vibe coding” model yet. Google emphasized its ability to generate and understand text, images, video, and code with seamless integration across its ecosystem, including Google Search, Workspace, and Android. The release comes amid a fierce AI arms race. OpenAI has pushed forward with ChatGPT 4.5 Turbo and the upcoming ChatGPT 5, while Anthropic has introduced Claude 3.5, each striving to outperform the others in reasoning, tool use, and real-world application. Benioff’s shift from ChatGPT to Gemini 3 is particularly notable given Salesforce’s longstanding partnerships with OpenAI and Anthropic, underscoring how rapidly executive sentiment is evolving as AI models become more capable and integrated into daily workflows.
