Even better, from what I've seen and experienced, LLMs can perform very differently based on how they're prompted and/or fine-tuned, so Alice's TaxGPT may be better than Bob's SmartTurboTax, etc. To the larger point, these could help make software a whole lot smarter and more tuned to personal preference. That, I think, is a selling point. As a developer, consider a basic OCR library used to power an app that helps your user track their spending by reading receipts and automatically inputting amounts in some database. An LLM like GPT-4 can do much more than read what's on it trivially. I can imagine an on-device model that has access to your health data can trivially read nutrition information on a label and suggest that maybe you shouldn't have that donut today... I don't know, but easily building smarter software sounds like a strong business case...
