Why don’t companies publish hashes of emitted answers so that we, eg teachers, could verify if the AI produced this result?

staticman2•8mo ago

It would be pretty trivial to paraphrase the output wouldn't it?

fenesiistvan•8mo ago

Change one character and the hash will not match anymore...

Atotalnoob•8mo ago

There are the issues others mentioned, but also you could write something word for word of what an LLM says.

It’s statistically unlikely, but possible

perdomon•8mo ago

Hashes of every answer to every question and every variation of that question? If that were possible, you’d still need to account for the extreme likelihood of the LLM providing a differently worded answer (it virtually always will). This isn’t how LLMs or hashing algorithms work. I think the answer is that teachers need to adjust to the changing technological landscape. It’s long overdue, and LLMs have almost ruined homework.

fuddy•8mo ago

Hashing every answer you ever give is the kind of thing that is done with hashing algorithms, the trouble is that the user can trivially make an equally good variant with virtually any (well an unlimited number of possible) change, and nothing has hashed it.

Ever heard of the meme:

"can I copy your homework?"

"yeah just change it up a bit so it doesn't look obvious you copied"

evilduck•8mo ago

Local models are possible and nothing in that area of development will ever publish a hash of their output. The huge frontier models are not reasonably self-hosted but for normal K-12 tasking a model that runs on a decent gaming computer is sufficient to make a teacher's job harder. Hell, a small model running on a newer phone from the last couple of years could provide pretty decent essay help.

Heck, use a hosted model for the first pass, send the output to a local model with the prompt "tweak this to make it sound like it was written by a college student instead of an AI"

BriggyDwiggs42•8mo ago

There’s an actual approach where you have the LLM generate patterns of slightly less likely words and then can detect it easily from years ago. They don’t want to do any of that stuff because cheating students are their users.

subscribed•8mo ago

This is exactly where users of English as second language are being accused of cheating -- we didn't grew with the live language, but learnt from movies, classic books, and in school (the luckiest ones).

We use rare or uncommon words because of how we learned and were taught. Weaponising it against us is not just a prejudice, it's idiocy.

You're postulating using a metric that shows how much someone deviates from the bog standard, and that will also discriminate against the smart, homegrown erudites.

This approach is utterly flawed.

haiku2077•8mo ago

I remember when my parents sent me to live with my grandparents in India for a bit, all the English language books available were older books, mostly British authors. I think the newest book I read that summer that wasn't a math book was Through the Looking Glass.

BriggyDwiggs42•8mo ago

I’m referencing a paper I saw in passing multiple years ago, so forgive me if I didn’t elaborate the exact algorithm. The LLM varies its word selection in a patterned way, eg most likely word, 2nd most, 1st, 2nd, and so on. It’s statistically impossible for an esl person to happen to do this on accident.

dietr1ch•8mo ago

I see the problem you face, but I don't think it's that easy. It seems you can rely on hashes being noisy and alter questions or answers a little bit to get around the LLM homework naughty list.

silisili•8mo ago

Just ctrl-f for an em dash and call it a day.

cye131•8mo ago

The new 2.5 Pro (05-06) definitely does not have any sort of meaningful 1 million context window, as many users have pointed out. It does not even remember to generate its reasoning block at 50k+ tokens.

Their new pro model seemed to just trade off fluid intelligence and creativity for performance on closed-end coding tasks (and hence benchmarks), which unfortunately seems to be a general pattern for LLM development now.

mchusma•8mo ago

I strongly dislike the “updating of versions” whenever possible. Versions are rarely better in all ways, makes things harder. Just make it version 2.6.

Aeolun•8mo ago

I think it’s pretty strange how time and time again I see the scores for other models go up, but when I actually use them it sucks, and then I go back to Claude.

It’s also nice Claude just doesn’t update until they have actual improvements to show.

jacob019•8mo ago

Claude is great for code, if pricy, but when it gets stuck I break out Gemini 2.5 pro. It's smarter, but wants to rewrite everything to be extremely vebose and defensive, introducing bugs and stupid comments. 2.5 flash is amazing for agentic work. Each frontier model has unique strengths.

dandiep•8mo ago

I wish Google would provide a WebRTC endpoint for their Live mode like Open AI does for their Realtime models [1]. Makes it so much easier to deploy without needing something like LiveKit or Pipecat.

andrewstuart•8mo ago

I love Gemini.

I just wish they’d give powerful options for getting files out of it.

I’m so sick of cutting and pasting.

It would be nice to git push and pull into AI Studio chats or SFTP.
