Mainstream media is where you get the news a month after I first write about it. Dealbook: "OpenAI’s latest GPT-6 Astra model is clicking with business users. New data from Ramp, an expense management start-up, shows that OpenAI’s models overtook Anthropic’s this past week in share of business spending." "Astra had the largest market share of any single A.I. model last week, according to Ramp, with nearly 19 percent of dollars spent, in front of Anthropic’s Claude Opus 5, which had 17 percent."
