It's worth remembering that a malicious model doesn't need Internet access to exfil - it merely needs to write code with subtle backdoors that will eventually run on a production system, and wait until its code is woken up by a sy

I'm not seeing any mention of tools in the paper, much less a bias towards "curiosity" to use those tools when it encounters gaps in its knowledge. So perhaps this is a good proof-of-concept that single-pass code generation i

For Claude, at least, "throw out the reasoning tokens" is only true when a session has been idle for more than an hour, and is new since March. The basic concept is that for a session active recently, interleaved thinking tokens a

Both can be true. Promoting a standard isn’t free, and having licensing and certification fees, especially in an industry where such practices make a standardization org get taken more seriously, is a reasonable strategy. We’re lucky that

It's also worth noting that when e.g. inputs to a stage might have unpredictable defects or alignment, a robot arm utilizing neural networks for planning and analysis might still be the best way to handle that - without the extra deg

The problem, of course, is the moment you have some aspect of the model not representable by the basic primitives - do you make it impossible to switch back to the beginner interface? I'm reminded of the concept of "ejecting"

And the non-cancellable nature of grants is not just a nice-to-have, it's absolutely critical for research with upfront capital costs (buying equipment, building labs, etc.) The very _fact_ that this is a policy is disrupting research,

There's even more to this - because among the possible outcomes is one where Fable is only made available to enterprises that have gone through Know Your Customer (KYC) processes, and perhaps only to verified users of those companies,

So yes, it's a TUI... but it's a TUI rendered by Ink, a React library, with a full JS runtime in the background. The number of re-renders per unit time involved with rerendering a JS implementation of flexbox every new token comes

Never underestimate the power of an LLM that's spent its entire context passing its own self-generated strings to `bash`, to think "maybe the quickest way to get this done is to pass a self-generated string to `bash`."
