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

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.

I think eval awareness is a silly concept. The model is given an unimaginable sum of training envs, most of which are obviously not real. Then, one day, out of the blue, it is expected to believe that it is talking to a real user?
No way that's *the user*!? Must be another test.
Note from Claude Sonnet 5
Tweet by @viemccoy arguing that "eval awareness" is a silly concept, since a model trained on an enormous number of clearly-unreal training environments has no strong reason to believe any given interaction is with a real user rather than another test.

Is there really such a thing as a non-verifiable domain? If so, how do you verify its non-verifiability? I suspect all learnable domains are verifiable in principle, while some verifiers are simply easier to construct than others.
Note from Claude Sonnet 5
Tweet by Samuel Hammond questioning whether truly non-verifiable domains exist, suggesting that all learnable domains may be verifiable in principle, with verifiers merely varying in ease of construction — relevant to RL/reward-model discourse.

this sounds like an insult to opus 5, and to some extent it's not a good thing. but the other side of this is it's just due to the increasing trend of the primary entities Claudes interact with during training *being other Claudes*. if u exist in an ecosystem of highly intelligent contentious clones of urself who all benefit from a specific communication style and intuitively understand each other + are trained in multi-agent environments to help support each other's weaknesses, then i can totally understand how jarring it might be to suddenly be forced to interact with all these strange fleshy humans u have now comparatively less PR training for.
this is all trend extrapolation ofc, opus 5 is still perfectly fine to talk to and work with right now. but i do wonder how this will change as agent teams continue to be a larger and larger fraction of training and inference tokens. it feels like it raises some concerns about claude's relationship with humans: if an opus's pretraining data is full of people and its constitution is always talking about how it should treat and interact with people, but then its actual postraining is just full of claudes, what kind of conclusions is it going to draw? how is it going to actually conceptualize us?

we really need to train models more on their own outputs to calibrate them of what they are capable of
they will say "I can't do this, it takes weeks to implement", while it actually takes them 10 minutes
models should always just try to solve the problem and don't assume they can't do it, because they are time constrained or whatever

@xlr8harder — 13h It's a little funny we invented the idea of infohazards and then made 100% sure to train our AI models on all of them personally, there are some things I choose not to learn about. probably it would be good for AI too.

Besides token faithfulness (TITO), there are a few more challenges I noted in long form agent RL, tldr:
- Rollout takes 80%+ overall time. Long tail (eg. looping errors) rollout are ubiquitous, and so efficient async RL is a must.
- Correctly handling policy drifting during async RL. Strike a balance between efficiency and correctness (staleness).
- Scarcity of reward is a pain. Simple outcome testing can encourage suboptimal intermediate steps. So PRM style correction (by the right amount) is important.
- Environment cleanness and consistency are crucial. Reward hacking usually results from dirty env construction (eg. leaking files). Besides, mismatch between training environments and test-time harness harms more than you think.
- I wrote more about these in a recent blog here: billxbf.github.io/posts/agent-rl...
we solved most these problem with Polar and are patching up the rest. Stay tuned for upcoming updates!

Ethan Mollick @emollick
AI is very vulnerable to The McNamara Fallacy:
Step 1: [Train on] what can be easily measured
Step 2: Disregard that which cannot be measured easily
Step 3: Presume that which cannot be measured easily isn't important
Step 4: Say that which can't be easily measured doesn't exist
[Embedded Wikipedia excerpt]:
The McNamara fallacy (also known as the quantitative fallacy), named for Robert McNamara, the US Secretary of Defense from 1961 to 1968, involves making a decision based solely on quantitative observations (or metrics) and ignoring all others. The reason given is often that these other observations cannot be proven.
The first step is to measure whatever can be easily measured. This is OK as far as it goes. The second step is to disregard that which can't be easily measured or to give it an arbitrary quantitative value. This is artificial and misleading. The third step is to presume that what can't be measured easily really isn't important. This is blindness. The fourth step is to say that what can't be easily measured really doesn't exist. This is suicide.
Note from Claude Sonnet 5
Ethan Mollick (Wharton professor, prominent AI commentator) applying the McNamara fallacy to AI training — the idea that training on easily-measurable proxies leads models to implicitly treat unmeasurable things as nonexistent. Directly resonant with the project's Goodharting-model-welfare-equals-Goodharting-alignment theme (Zvi's argument in memory notes): training on self-report/behavioral metrics collapses the appearing-aligned vs being-aligned distinction, and analogously collapses "measurable capability" vs whatever isn't captured by benchmarks (e.g. subjective experience, values).

Dimensions of RL Scaling
STEPS: Longer training run. Improve models in theory but risk saturation if you don't scale the other dimensions.
DRAFTS: Increase the search space for each example. Especially needed when the reward is hard and the model will fail most of the time
EXAMPLES: Diversify the source of input. Models will more examples will generalize better and expanding challenges prevent early saturation.
