Doesn't sound like you've been following the space. They exist, it's called LoRas. The Unsloth project is huge and whole purpose is to make it easy to train to train LLM LoRas. The reason you don't see LoRas on their own is because people who fine tune models merge them back into the base and ship the full model weights instead

Also see LoRAX, it's an inference engine that exactly does this, it can serve many LoRas off a single base model

I see, so you're off the opinion anthropic could provide a loras adaptation per user ready for use to enable timely response for every subscriber.

It is an interesting thought to explore. I admit I'm not a specialist whatsoever on the topic, from my perspective that sounds like an incredible challenging ops problem.... But again, I don't work for anthropic and maybe they're up to the challenge as you seem to think.

If users get a fixed set/numbers of Paramus for LoRa - say 1-5% - it doesn't sound that crazy.

The crazy part is probably loading, running a model pr users - but if the untrained (unspecialized?) model can somehow stay resident - might be possible to load adjusted weights on demand?

I suppose each run now needs a different context pr user/customer anyway, for cache hit rate, if nothing else?

Anthropic need not care about this space. It's possible it's more worth it for them to dedicate their resources into making better base models.
