Lightcap: Current AI models are honestly not that good
“I think right now expectations are extremely high. Reality is still pretty bad, honestly. These models are not that good.”

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: Many enterprises mistakenly assume GPT-4 is the peak of AI
“A lot of companies think it's static, so a lot of companies think GPT-IV is the best the models will ever get. That's understandable. Every technology they've ever had to adopt has been relatively static.”

Lightcap: AI model scaling laws have held predictably consistent for six years
“I think it's how consistently the scaling of models has worked. It still breaks my brain. Like I don't, maybe I've been, if we've, I've watched the same trend line for six years now, but I still find it incredible that you can make these models bigger and they…”
