The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 13 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
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: 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 is four to five times more accurate than predecessor models
“GBD-V, I think depends on how you measure it, but it's, you know, four to five times more accurate than its predecessors.”
Lightcap: Partners Call GPT-5 Most Capable Coding Model
“I mentioned companies like Cursor, JetBrains, Windsurf you know, Cognition and others that we work with who anecdotally are all you know, have all said that GPT-V now feels like the most capable coding model, whether that's in an interactive coding environment…”
Lightcap: GPT-5 dynamically chooses whether to reason deeply per query
“GPT-V is it's our next generation flagship model. It does something really interesting, which is it actually combines into one model the ability to dynamically choose whether to think hard about a problem and reason about it to give you an answer or not.”
Lightcap: GPT-5 is vastly improved in writing, coding, health, and speed
“GPT-V abstracts all of that, so it makes that decision for you and it's actually a smarter model, so you're gonna get a better answer in all cases, regardless of whether you're using the thinking mode or not and it's vastly improved on things like writing, cod…”
Lightcap: Base GPT-5 beats GPT-4o even without added reasoning time
“Even though if you don't allow any thinking time you still get a typically net better answer than you would for one of our non-thinking models like GPT-IV-I.”
Lightcap: GPT-5 beats previous models on SWE-bench and health benchmarks
“It scores better on things like Sweebench. It scores better on all the kind of academic evals that we put it through. This one in particular, we actually made a real emphasis to have it score better on certain health benchmarks. So It's better at medical reaso…”
Lightcap: GPT-5 bakes in tool use and longer-horizon reasoning
“So using tools, for example, is something that really thinks really important for overall intelligence, GPT two and three couldn't really do that as well. GPT-IV could do it in a more nascent way. And now GPT-V, you get that baked in with the benefit of these …”
Lightcap: AI will not replace general practitioners
“I don't think it'll replace GPs, but what I think it helps people do is become, have more agency in their journey a little bit more control over their, you know, the process of managing care.”
Lightcap: GPT-5 will feel dramatically different to average users, not power users
“And so we expect that like for, yeah, for the average user, it will feel dramatically different. Maybe for the kind of upper echelon of power user, it may not feel as different.”
Lightcap: OpenAI Cost Cuts Have Historically Driven Greater Consumption Surges
“In OpenAI's history, every time we've cut costs, we've seen typically some corresponding increase in consumption that usually outweighs the cost cut.”
Lightcap: Most free ChatGPT users haven't used reasoning models yet
“Most of them have actually not experienced the power of the reasoning models. They mostly are using GPT-IV-O and, you know, they mostly are kind of using it for this very kind of you know, turn-based kind of like very quick you know, back and forth, almost sea…”
