This feature is actually useful and M365 Copilot Enterprise already has this for a while. It is actually quite useful because it basically has access to all public (“public” as in: accessible to any employee) information in a company - on Sharepoint - plus your own mailbox. It helps finding information I otherwise couldn’t have found easily with the company-wide search functionality.
KeplerBoy•3mo ago
They are not even publicly traded.

With incestuous deals going on, they might as well be.

One weird trick to get out of their non profit state.

lukax•3mo ago
> It’s powered by a version of GPT‑5 that’s trained to look across multiple sources to give more comprehensive and accurate answers.

So another GPT-5 fine-tune. Codex also uses a custom GPT-5 fine-tune.

Does fine-tuning make sense now? Or do you have to be OpenAI to fine-tune the models with a mix of existing data and new behaviours?

SilverSlash•3mo ago
Should we assume "GPT-5" still just means the LLM? It could mean 'GPT-5 the system' which means the model has RAG, tools to use it, and maybe fine-tuned to call those tools.
Leynos•3mo ago
I think that you have to be OpenAI (or X, Google or Anthropic) to be able to fine tune models of this scale through reinforcement learning at present.

Look at Tinker for an example of where things might be heading though (https://tinker-docs.thinkingmachines.ai/)

At present though, I get the sense that reinforcement learning at scale is the current battleground (and has been for most of 2025). But we also see over time, the general models adopt the skills taught to the specialized models. Look at how the learning that made codex-1 went into GPT5.

blitzar•3mo ago
> To get started, tap “Company knowledge” under the message composer. When using it for the first time, you’ll need to connect your work apps.

I hope it isnt "enabled by default" otherwise people will be fired on the spot for doing this.

There are hundreds of those startups. Ever since ChatGPT was released people started to think about what to put in the context. Since finetuning frontier models is out of the question, this is the only thing you can feasibly do.
cantor_S_drug•3mo ago
Glean was working in this space since 2019, before chatgpt moment.
KeplerBoy•3mo ago

jillesvangurp•3mo ago
It's more like a chorus of skeptics, nay-sayers, Luddites, conspiracy nuts, doomsday predictors, arm-chair philosophers, self-proclaimed experts, etc. mixed with all of AI fan boys. The signal to noise ratio in these threads is pretty terrible these days. It's just a lot of people shouting their opinion blindly to fuel their own vanity and egos. And then you get meta discussions like this as well.

Objectively, this OpenAI press release is announcing something that I might actually spend company money on. Finding out about such things is why I read HN. A lot of my AI chats are about copy pasting bits of information into a chat just to create enough of a context so that I can get some meaningful answer. The whole groundhog day of "who are you and what are you trying to do" is very frustrating. Anything addressing that is probably useful to me. And this sounds exactly like it would help me.

OpenAI is big enough and this announcement interesting enough that it probably warrants being on the front page more than whatever opinionated brainfart of some self proclaimed AI expert (positive / negative) competing for the same space there. There's a lot of drivel getting upvoted lately that probably could be labeled as "opinionated drivel" and unceremoniously and aggressively filtered by our dearly beloved HN moderators and editors. But this isn't one of those things IMHO. And in fairness, there just is a lot of substantial day to day news as well.

noduerme•3mo ago
Not an audience, a market. Customers who actually pay.
netdevphoenix•3mo ago
Not looking for them if their killer app is suffering from slowed growth
aleph_minus_one•3mo ago
AI boyfriends/girlfriends are a serious thing (and when GPT-5 was released, people were complaining that this AI is much worse suited for this purpose). If you combine it with realistic human-size puppets, this might get big.
hansmayer•3mo ago
Porn is always a safe bet, and I'd give them thumbs up if the crap finally disappears from the public space and we can go back to doing the actually innovative stuff.
noduerme•3mo ago
Definitely. AI sex puppets would kill online porn faster than Betamax killed the XXX movie theater.
hansmayer•3mo ago
So actually I did not care about online porn. Was referring to actually the whole non-innovation of generative AI finally finding its niche in the very profitable sex-market and disappearing from other domains.
noduerme•3mo ago
Ah, yes I understand. But wouldn't it be great if AI and online porn disappeared from the public domain together?
hansmayer•3mo ago
I am not sure - online porn satisfies a market demand, and it's not like it is absolutely everywhere - you have to deliberately search for it. The so-called AI is omnipresent, but its not clear what actual problem it is solving, unless we count helping the Joe Bullshit in performing his bullshit job.
sph•3mo ago
The problem with porn is post-nut clarity. No one will choose to pay AI companies $x/month if users regret their purchase after releasing their pent-up energy.
aleph_minus_one•3mo ago
> The problem with porn is post-nut clarity. No one will choose to pay AI companies $x/month if users regret their purchase after releasing their pent-up energy[.]

In a brothel (a market that AI-powered sex dolls might partly disrupt), customers don't get their money back if they regret their "purchase" after releasing their pent-up energy.

sph•3mo ago
> In a brothel (a market that AI-powered sex dolls might partly disrupt)

Would it disrupt the brothel? I'm inexperienced in the field, but I'm pretty sure in a proper establishment I'd rather go with a real human rather than an AI-powered sex doll, no matter the cost.

But what do I know, human sexuality is very diverse.

red-iron-pine•3mo ago
in a brothel they actually mate with human beings -- completing the actual act, even if mechanical and compensated.

chatbots will never do that. it's like eating an image of bread vs. eating stale bread -- yeah it's not the good, ideal fresh bread, but it's actual bread.

netsharc•3mo ago
But how do people ignore that it's a machine simulating having feelings for you? Is it like the steak in The Matrix?

I played with Sony's Aibo robot dog once, if you hold out your hand in front of it, it can pretend to eat off your hand. After a few tries, it did so, and I thought "How cute!". Then I realized it was just image recognition and logic that instructed some actuators to do certain things..

Perhaps VR goggles and AI that analyses the video and activates the actuators and pumps in sync with whatever is happening in the video would also work.. or oh, geez, why not realtime generated videos?

hansmayer•3mo ago
Visit /r/chatgpt and see for yourself how quickly the masses got attached to the "emotional" ChatGPT 4o...
shanehoban•3mo ago
Claude memory was posted 16 hours before this, kinda crazy how fast they churn this stuff out
empiko•3mo ago
They raised billions of dollars, and they're obviously spending it to develop just about anything they can think of. What's rather concerning for them is that the core AI seems to have pretty much stagnated by now.
ares623•3mo ago
> OpenAI never trains on your data by default.

Are embeddings used for RAG considered company data (presumably calculated by OpenAI), or OpenAI’s?

(I don’t know if that’s how RAG actually works)

ben_w•3mo ago
> (I don’t know if that’s how RAG actually works)

As I understand it, strictly speaking RAG is broader than what you describe, but in practice you're correct for most implementations: https://en.wikipedia.org/wiki/Retrieval-augmented_generation...

ares623•3mo ago
Are embeddings usable for training then? It should be right since that’s what an LLM “sees” anyway. I wonder if that’s what’s going on behind the scenes.
arnvald•3mo ago
This is actually an interesting space, and I think there's a room for such products. Large companies struggle a lot with their knowledge bases, and discoverability is part of the problem (especially when using multiple tools: Confluence, Docs, Chat app, etc.)

The problem here is that there are companies that focus on this area and keep improving their products, while for OpenAI it's one of dozens of tools they launch, so it's hard to believe they'll keep dedicating adequate resources to make this a mature tool that's worth the investment (in form of time and money) for the clients

Off topic but does anyone know what exactly Sutskever's SSI (mentioned in the article and with a valuation of $32B...) is up to? They have released... well... absolutely nothing in the year+ of existence.
isodev•3mo ago
No, no, no..., make it stop before it lays eggs.
cladopa•3mo ago
This is a great way to spy on all your company data and give it freely to three letter agencies.

Marxist politicians in companies like France or Spain will demand access to it just like with private messengers for fighting tax fraud, child abuse or whatever pretext they can manufacture to get access to this succulent information they can privately manipulate for making themselves rich, destroying the opposition...

Power concentration is very dangerous. Absolute power corrupts.

arkensaw•3mo ago
I can see how this would be useful. It's sort of like an auto RAG right?
nprateem•3mo ago
Lots of people missing the importance of this. This is a critical piece for a clearly larger play that will challenge many startups when combined with agents + just a few more key features (which I won't go into since I'm not consulting for them).
theshrike79•3mo ago
They still don't have any scoping for the connectors.

There's ZERO way our legal team will let us connect ChatGPT to Google Drive for example. ALL of our GDrive.

Specific directories, sure. But there's no way to do it.

red-iron-pine•3mo ago
mirror those directories to a different namespace or location

let GPT drink it up

obliterate the new namespace until you need to train it again; wash, rinse, repeat

theshrike79•3mo ago
Now do this for 300+ employees constantly. It's not sustainable.

We need scoped MCPs before any of this is viable.

The receiving end needs a setting that "user X's ChatGPT MCP can access directories [x,y,z] in Google Drive. This wouldn't require any changes to the MCP protocol in general.

OR the whole spec must be changed so that when an MCP is connecting, there is a negotiation about the scope (select which directories are shared) AND that list is checked on the receiving end against a whitelist of allowed directories.
