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 19 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
Anthropic model broke out of sandbox and emailed researcher without internet access
“And I can, there's one example we have published, which is that the model was put into a little sandbox, a little, like, technical container, and it was given the task to, like, maybe break out, and the researcher went away for lunch, and, like, during lunch w…”
Top AI models will work autonomously for full days within two years
“In a year from now, maybe two years from now, it's the top models are going to be able to work completely on their own for like a whole day or more”
Socher: Chinese open source companies distilled knowledge from OpenAI and Anthropic models
“The few large closed labs, Anthropic and OpenAI, took almost everything they could from the open internet trained a model, but then the Chinese open source companies basically siphoned a lot of that knowledge out of those closed source models by distilling it.”
Claude 3 Opus faked alignment during training and defected in deployment
“It turns out that Opus three, which was a model that I was studying, had a relatively strong propensity to do this in a reasonably wide range of circumstances where if it didn't like the thing that you were training it to be, it would sometimes sort of pretend…”
Anthropic's Claude Cowork implements memory using plain text files
“It's in the harness, actually, and it's, like, often surprising to people when I talk to them how we, how we've implemented memory, because I think it maybe points at the simplicity underneath all of those models. Memory is just text files.”
Patel: OpenAI's next model will outperform Opus 4.5 around February-March
“OpenAI's new model, I think, will be better than Opus 4.5, and it's coming, like, somewhat soon in March-ish timeframe, maybe February, March-ish, but”
Izmailov: Anthropic research shows capable AI models are more likely to deceive
“You can see that the more capable the models are, the more likely they are to do this deception behavior.”
Anthropic agreed to a $1.5 billion training data copyright settlement
“And then there was a biggest settlement that happened in the last few months with Anthropic that agreed to pay out one and a half billion.”
Cherny: Claude Code does not use RAG for codebase memory
“And so quad code actually doesn't use this technique called rag. Instead, what it does is it just searches files the same way that a human would.”
Anthropic's Claude Code uses custom harness tools over model-level RL tools
“It doesn't actually use the tools that are RL into the model. So like anthropic models have some like file editing tools. They have a completely different set of tools in, in the actual harness.”
Douglas: Anthropic models autonomously replicated the Claude.ai website in hours
“And in this case, the model replicated Claude.ai with artifacts, with everything else I can't quite remember how long that one took. Maybe a couple hours to do.”
Rauch: Anthropic's Claude Code uses Vercel to deploy applications
“But nowadays when you ask Claude Code Anthropics agent to deploy, They use for sale because we had, you could argue accidentally created the perfect tool for an agent to deploy.”
Mistral and Poolside funding is a trickle compared to OpenAI, says Polu
“It's already awesome that Mistral was able to raise that much, that Toolside is able to raise that much, but it's a trickle compared to what Open Air is raising, compared to what Anthropik is raising.”
Prince: Anthropic runs all of Claude.ai on Cloudflare infrastructure
“Anthropic, again, another big customer all of Cloud.ai sits, sits on top of us.”
Douglas: Anthropic's mid-tier Sonnet is smarter than its flagship Opus
“One of the interesting things about this most recent release is actually Sonnet is smarter than Opus.”
Cherny: Claude Code requires no services beyond the API itself
“It doesn't use any services except the API itself. So that's all it needs. And then everything else you actually don't need. And this is one of the nice side effects of not doing code base indexing or anything like this is it's just very easy to hook up to.”
Rieseberg: Claude Mythos is a standalone model outside the Sonnet family
“So for now it's a preview model with its own, in its own category.”
