You can buy dedicates scanners who don't fuck with you.
CANON PIXMA MG 2440 which I have also has full Linux support OOB without the bullshit, either print or scan. But it's an old boy now, it can't do the kewl ayy oo tee bullshit like LAN printing
Well.... There is quite a bit of high precision manufacturing needed for the actual print heads... Something like a Dot Matrix straight from 1990s should be doable by people with appropriate CNC machines and shit, something like "Line Typers" (1950s-1970s automatic computer operated type writers) are manageable if you can precision mold metals
But an ink jet or laser jet? Naw big dawg that shit is complicated as fuck
If you can somehow manufacture the ink head, an ink jet printer is like 2 step motors and one really complicated print head on rails
You're misunderstanding tool use, the LLM only queries something to be done then the actual system returns the result. You can also summarize the result or something but hallucinations in that workload are remarkably low (however without tuning they can drop important information from the response)
The place where it can hallucinate is generating steps for your natural language query, or the entry stage. That's why you need to safeguard like your ass depends on it. (Which it does, if your boss is stupid enough)
The model ISN'T outputing the letters individually, binary models (as I mentioned) do; not transformers.
The model output is more like
Strawberry
<S-T-R>
<A-W-B>
<S-T-R-A-W-B>
<E-R-R>
<S-T-R-A-W-B-E-R-R-Y>
Tokens can be a letter, part of a word, any single lexeme, any word, or even multiple words ("let be")
Okay I did a shit job demonstrating the time axis. The model doesn't know the underlying letters of the previous tokens and this processes is going forward in time
No, this literally is the explanation. The model understands the concept of "Strawberry", It can output from the model (and that itself is very complicated) in English as Strawberry, jn Persian as توت فرنگی and so on.
But the model does not understand how many Rs exist in Strawberry or how many ت exist in توت فرنگی
For usage like that you'd wire an LLM into a tool use workflow with whatever accounting software you have. The LLM would make queries to the rigid, non-hallucinating accounting system.
I still don't think it would be anywhere close to a good idea because you'd need a lot of safeguards and also fuck your accounting and you'll have some unpleasant meetings with the local equivalent of the IRS.
Old joke;
What do you say when you're flying a plane designed with a Pentium™?
IEEE!
(This dates back to the Pentium float bug. It's an antique)
