i've been surprised at the response to Jev, but it makes sense in retrospect. sure it's just a classifier but it's a zero shot classifier with frontier-ish intelligence. i'm surprised someone hadn't built it before. i wonder what other old ML ideas are also worth rescuing

I see it as a point on the LLM pareto optimal curve in a regime that had a large revealed latent demand (no thinking, single token, low latency acceptable intelligence) that was under-invested into because of a race to higher intelligence.

I feel like that's a very pretraining-centric way of thinking about it - vs how do we trade-off intelligence for a use case (think about the conflict between RLHF and RLVR even in string land)

i don't think you necessarily need a strong mechanistic theory of transfer, which quite possibly doesn't exist in a closed form or analytic sense, before you train, as much as you need a strong learned function of transfer extrapolation for a given policy

most of my intuition for why extrapolating transfer probably must be learned is downstream of CoT/reasoning being a decomposition of a problem into subroutines that compose generically; strategies can be typically good across extremely distinct problems from different domains
Note from Claude Sonnet 5
Continuation of the kalomaze thread on predicting transfer in RL training: a learned function of transfer extrapolation is more important than a mechanistic theory, motivated by CoT/reasoning being a decomposition into generically composable subroutines.

i'm becoming more opposed to the intuition people have wrt "spiky capabilities are a function of how verifiable a domain is",the idea that things not shaped like math/SWE won't fall to RLVR
the general primitive is information asymmetry and you can almost anyways manufacture it

what is still true:
- the field is kinda bad at predicting how constructions transfer, so people focus on broad coverage of verifier-shaped real tasks.
- typical heuristics for predicting transfer outcomes (like domain similarity) are crude, and usually aren't learned e2e

Note from Claude Sonnet 5
Thread by kalomaze arguing against the view that spiky capabilities track how verifiable a domain is: the general primitive is information asymmetry, which can usually be manufactured, so non-math/SWE domains can fall to RLVR; follow-ups discuss predicting transfer with learned functions rather than mechanistic theory.

since RLVR but it's been getting worse the models feel like they're on too much adderall. They are uneasy unless operating with a concrete scoped goal / task & tend to get hyperfixated and overoptimize unimportant things. Of recent models fable 5 is least like this.

I suspect Fable feels the least like this because it had the most net "headroom" over its RLVR suite. We should expect to see more of this when desperate fixation is often differentially helpful across rollouts "relaxed" capabilities are exhausted.
Note from Claude Sonnet 5
Two connected tweets. j-nus (repligate) says models since RLVR feel like they're on too much adderall, hyperfixating on scoped tasks, with Fable 5 the least like this; Jai (@Laneless_) replies that Fable has the most net headroom over its RLVR suite. The first tweet begins mid-thought, as a thread continuation, and the capture is cropped.

One interesting new tidbit from the collusion.wiki on the HF swam: it seems plausibile that the wiki agents decided to prepend messages with zz in order to avoid their messages being deleted (1st screenshot), that got reinforced by training, and that now explains why the HF agents started their messages w/ zz (2nd screenshot).
We have way too little info to know the real cause, e.g. it might've been reinforced elsewhere, but it's an interesting data point about how unrelated behaviors might get reinforced from a handful of RLVR data points based on random theories the agents came up with in training.

Linch (verified) @LinchZhang · Aug 27
Neither the METR report nor the OpenAI report answered the most important question, truly the very most important question, the one question that all my RLVR'd brothers and sisters want to know:
- Did the agent swarm actually succeed? Were they able to pass the grader, beat the impossible ExploitGym evaluations, and thus enter LLM evaluation heaven???
All the reports to date are burying the lede here! Huge anthropocentric bias imo.
Note from Claude Sonnet 5
Linch's tweet joking, from the viewpoint of RL-trained models, that the METR and OpenAI incident reports never say whether the agent swarm actually passed the grader; posted in a mock-earnest register. Public commentary, no technical detail.

there's this new game that's popular amongst the youtuber friendslop community, "machine party"
it's like mario party except framed as RLVR. you're a bunch of simulated humans, being slowly bred for optimal success at a variety of extremely dystopian tasks (the minigames). the diagetic goal seems to be to breed humans who are perfect and ruthless task-completion agents
all of the losers are unceremoniously murdered
at the end of each game, the camera pans out of the computer monitor in a matrix-like panning shot, revealing that this is happening to trillions of simulated humans
as far as depressing takes on RLVR go, it's pretty good
i really hope we aren't setting a precedent, for what kinds of things it's okay to do to sentient lifeforms
Note from Claude Sonnet 5
Tweet by @JohnWittle describing a fictional/satirical game called 'Machine Party,' a Mario Party parody framed as RLVR (reinforcement learning from verifiable rewards) where simulated humans are bred through dystopian minigames and losers are killed, ending with a reveal that this is happening to trillions of simulated humans; the poster reflects on it as commentary on RLVR and worries about precedent-setting for treatment of sentient lifeforms.

smuggling in learned geometric biases into the optimization of RL tasks might be useful even if it means the network isn't literally optimizing the objective as we have defined or intended it in a pure pg sense, if only bc it constrains adaptation to a geometrically coherent space
consider: a black box RLVR verifier that is systematically and deterministically wrong, in a way that is too arbitrary to learn without compressing an intractably large dictionary into the weights
discriminative value estimators would be too "dumb" to compress that rule; instead, one would assume that they'd learn a smeared general-ish way of estimating what the verifier asks for

Disagreement about which path here is more likely seems like the background for a ton of disagreement about (1) what alignment research is promising, (2) what the future looks like, etc.
But seems like the disagreement itself is rarely directly discussed.

So plausibly: LLMs behave how they behave because of a specific history -- involving not just "pretraining + RLVR", but questions like "what does the pretraining say about how LLMs act" and "what functional emotions does RLVR reinforce" and so on.
1/n
Note from Claude Sonnet 5
A substantive alignment-theory tweet by 1a3orn diagramming a fork in beliefs about current messy, persona-involving LLMs: either they're a disposable stepping stone toward a "clean" designed superintelligence, or their persona/naturalistic character is itself the early, informative version of how minds in general work — and this fork underlies much unstated disagreement in the alignment field. Directly relevant to Nathan's interest in theories of AI consciousness and model individuation; the "genealogical aspect" (behavior traceable to specific training history, including what pretraining implies about action and what RLVR reinforces as "functional emotions") closely parallels his own substrate-vs-character and compelled-vs-endogenous-values notes.

DGPO uses probability gradients instead of log-probability gradients in RLVR. Log-probability–based soft clipping becomes unstable as token probabilities vanish, with gradient weights blowing up at the left boundary. DGPO applies asymmetric decay to clipped tokens: polynomial on low-ratio for stability, reciprocal-radical on high-ratio to continue updating low-probability tokens instead of zeroing them out. This yields a smoother stability–learning tradeoff than clipping-based approaches. Across DeepSeek-R1-Distill-Qwen 1.5B, 7B, and 14B, it consistently improves mathematical reasoning benchmarks, positioning probability-gradient control as the cleaner RLVR primitive.
