The marketing copy and the current livestream appear tautological: "it's better because it's better." Not much explanation yet why GPT-5 warrants a major version bump. As usual, the model (and potentially OpenAI as a whole) will depend on output vibe checks.

We’re at the audiophile stage of LLMs where people are talking about the improved soundstage, tonality, reduced sibilance etc

Well, reduced sibilance is an ordinary and desirable thing. A better "audiophile absurdity" example would be $77,000 cables, freezing CDs to improve sound quality, using hospital-grade outlets, cryogenically frozen outlets (lol), the list goes on and on

It’s a common misconception, I doubt they know themselves and GPT 5 doesn’t tell them otherwise because it’s the mist common in explanation in the training data.

A quite good example of AI limits

Damn, you guys are toxic. So -- they did not invent AGI yet. Yet, I like what I'm seeing. Major progress on multiple fronts. Hallucination fix is exciting on its own. The React demos were mindblowing.

When you have the CEOs of these companies talking about how everyone is going to be jobless (and thus homeless) soon what do you expect? It's merely schadenfreude in the face of hubris.

Looks like the predictions of 2027 were on point. The developers at OpenAI are now clearly deferring to the judgement of their own models in their development process.

Hahahhahaa that’s a good one

This is the inverse of the "$2000/mo tier", and I'm kind of disappointed TBH.

It is frequently suggested that once one of the AI companies reaches an AGI threshold, they will take off ahead of the rest. It's interesting to note that at least so far, the trend has been the opposite: as time goes on and the models get better, the performance of the different company's gets clustered closer together. Right now GPT-5, Claude Opus, Grok 4, Gemini 2.5 Pro all seem quite good across the board (ie the…

Companies are collections of people, and these companies keep losing key developers to the others, I think this is why the clusters happen. OpenAI is now resorting to giving million dollar bonuses to every employee just to try to keep them long term.

Key developers being the leading term doesn’t exactly help the AGI narrative either.

Its not fully wrong but its a typical example of how simplified scientific explanations have spread everywhere without personal verification of each person involved in the chinese whisper

Is GPT-5 using a new pretrained base, or is it the same as GPT-4.1?

Given the low cost of GPT-5, compared to the prices we saw with GPT-4.5, my hunch is that this new model is actually just a bunch of RL on top of their existing models + automatic switching between reasoning/non-reasoning.

Short anything that’s riding on AGI coming soon. This presentation has gotten rid of all my fears of my children growing up in a crazy winner take all AGI world.

Don’t fear AGI, fear those who sell something as AGI and those who fall for it
