Benioff Switches From ChatGPT to Google’s Gemini 3 as Model Climbs Rankings and Pressures OpenAI

OpenAI has acknowledged competitive pressure from the launch, with Google leveraging its ecosystem to speed uptake.

Overview

  • Salesforce CEO Marc Benioff said two hours with Gemini 3 convinced him to stop using ChatGPT, calling the leap in reasoning, speed, and multimodal output "insane."
  • Gemini 3 quickly rose to the top of public leaderboards such as LMArena and drew praise from industry figures including Andrej Karpathy, Patrick Collison, and Sam Altman.
  • Google positions the model as its most capable yet, highlighting native multimodality across text, images, audio, and video, plus very large context windows and an optional Deep Think mode for harder problems.
  • Google has rolled the model into Search, apps, and developer tools, while OpenAI still leads on usage with roughly 800 million weekly active ChatGPT users versus Gemini’s reported ~650 million monthly users.
  • Reporting indicates OpenAI is bracing for "rough vibes" and near‑term headwinds as Alphabet’s shares advance toward a $4 trillion market value on optimism about Gemini and Google’s scale and chip assets.
