OpenAI's strategy is to be a platform company, not to compete with customers on the application layer.

“I don't think we should go build every product category. I don't think we should like go try to compete with all of our customers. I don't think we should try to like subsume the entire economy. I think we should offer this platform and try to have 100 million new businesses and 8 billion people use it in all kinds of new ways.”
