I can't really say I know whether the outcomes are good as I won't be told to what extent the output makes it into production models, and I don't even always know which company it's for. But I know at least some of it is being used for "general" models. I do more code-related work than general purpose as it's the work I find most interesting, but the highest paid contract I've had in this space so far is for a general-purpose model that to my knowledge isn't available yet, for a model from a company you'd know (but I'm under strict NDA not to mention the company name or more details about the work).
