That's the least practical solution of all (I say that as one of the few people in the world actually working on an orbital recycling project), especially if your technical advantage is launch, not inference chip manufacture. Apart from anything else, these giant satellites in LEO still need refuelling every five years, otherwise they'll just burn up in the atmosphere.

Replacing chips with newly launched chips on a refuelling cycle (and keeping all the heavy structural elements) is well within the boundaries of near term technology, but still involves enough mission and design-for-serviceability complexity to make it not obviously better than the 5 year recycle cadence Starlink and other modern constellations operate on.

Manufacturing newer, better chips in a microgravity environment using exactly the same material and plant technology as older chips is another thing entirely, particularly if you don't happen to own Nvidia et al's closely guarded trade secrets on how to make inference chips that are actually competitive and still aren't fully self sufficient even after the magical technology has been introduced because you need to top your massive satellites up with gas on a periodic basis....
