Tokens for the token throne?

More like Anthropic and OpenAI are in a competition to see who can release the most pointless products in the shortest amount of time.

They are not even publicly traded.

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.

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.

ai isn't a bubble.

My startup is working on a similar problem ... inbound in 5 ...

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.

They already have The Killer App - ChatGPT

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.

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.

> (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...

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.

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
