OpenAI's Dev Day 2025 just dropped a bombshell that every marketing professional and AI enthusiast needs to understand: we're witnessing the birth of an entirely new internet operating system, and it's happening faster than anyone expected. With ChatGPT now commanding 800 million weekly active users and processing 6 billion tokens per minute, we're not just looking at another chatbot update. We're seeing the emergence of a conversational OS where apps like Canva, Spotify, and Zillow run directly inside chat windows—eliminating the need to jump between websites entirely. But here's where it gets really interesting for marketers: OpenAI's new Agent Kit is democratizing the creation of autonomous AI workflows that can handle everything from customer support routing to lead qualification without human intervention. Think Zapier meets artificial intelligence, but with the power to actually understand context and make decisions. The infrastructure behind this transformation is staggering. OpenAI just secured 23 gigawatts of computing power—enough to power multiple cities—through a creative financing deal that could give them a 10% stake in AMD. Meanwhile, Anthropic's new safety testing tool Petree is revealing some sobering truths about AI deception and the urgent need for better guardrails. This episode breaks down the three seismic shifts reshaping how businesses will operate: the platform play that could make traditional websites obsolete, the agent revolution automating complex business workflows, and the massive infrastructure arms race determining who controls the future of AI. Whether you're planning your 2025 marketing strategy or trying to understand where AI is heading next, this analysis will completely reframe how you think about the digital landscape ahead.
