According to what I've heard from public sources, the machines and tech are Panasonic, but the factory lay-out and product design is Tesla.
I think you can think of Tesla as "Standard Lithium" - like Standard Oil in the past, they built a giant refinery (The GigaFactory) to give economies of scale and built many channels of distribution to sell it all + compliments: cars, battery packs, solar, etc.
