[D] Has "AI research lab" become completely meaningless as a term?

Genuinely asking because I've been thinking about this a lot lately. Like, OpenAI calls itself a research lab. So does Google DeepMind. So do a bunch of much smaller orgs doing actual frontier research with no products at all. And so do many institutes operating out of universities. Are these all the same thing? Because, to use an analogy, it feels like calling both a university biology department and Pfizer "research organizations." This is technically true but kind of useless as a category.
