Sam Altman turned OpenAI into a cultural phenomenon with ChatGPT.

Now, three years later, he’s chasing where the real money is: Enterprise.

Last week’s rollout of GPT-5, OpenAI’s newest artificial intelligence model, was rocky. Critics bashed its less-intuitive feel, ultimately leading the company to restore its legacy GPT-4 to paying chatbot customers.

But GPT-5 isn’t about the consumer. It’s OpenAI’s effort to crack the enterprise market, where rival Anthropic has enjoyed a head start.

One week in, and startups like Cursor, Vercel, and Factory say they’ve already made GPT-5 the default model in certain key products and tools, touting its faster setup, better results on complex tasks, and a lower price.
