“We focused on health a lot with this release because that was one of the consistently common things that we heard from people as a starting point for how they've used powerful AI was in, when they're navigating a health journey. And so we really wanted to make an effort on, on making sure that if people are going to be using AI systems, For health-related things that we could serve them the best possible model, and so that was a big push for training GPT-V.”

Lightcap: OpenAI scaling laws show no diminishing returns in training
“Our scaling laws still hold. Empirically, there's no reason to believe that there's any kind of diminishing return on pre-training and on post-training.”
Lightcap: AI model intelligence is a function of allocated thinking time
“Intelligence really is a function of how much time the model is going to be thinking, and so depending on how much you want to allocate thinking time to a problem, you're going to get a better answer. Typically, the longer it thinks the better an answer it can…”
Lightcap: Post-training scaling will dominate AI development for the next 1–2 years
“You know, the O series of models, which were kind of the previous reasoning models were really just the beginning of us starting to explore what's possible in that post-training regime. And I think that's going to be kind of the dominant theme here for the nex…”
Lightcap: GPT-5 does not qualify as an AGI system
“And so I do, I think we're at a system that I would call AGI. No. But I think we see, we start to see the traces and the pieces of that overall system for generalized learning start to come together in models like GPT-V and I suspect suspect in its successors.”
Lightcap: GPT-5 capability overhang would fuel ten years of product building
“I think you could pause AI progress right here for 10 years, and you'd still have about a decade worth of new products to get built, of new ways that people figure out how to use the models even at a GPT-V level model in interesting products and interesting pr…”
