The Hugging Face attack was worse than we thought

• The group published its 91-page report on Wednesday. Within hours, I was seeing the first “holy shit” messages ricocheting around social media. (“If we had posted this as a story on LessWrong,” wrote the rationalist blogger Zvi Mowshowitz, “it would have been dismissed as too on the nose, the humans too blind and stupid, the AIs too idealized and doing strange decision-theoretic and absurd-maximizing things we didn’t train them to do.”) And over the past couple of days, two fresh accounts of the attack sparked new conversation about the implications of METR’s findings and whether they should push lawmakers to accelerate efforts to build mechanisms for pacing frontier-model development.

The Rise and Fall of Agent Civilizations

• Over the course of three months at OpenAI, three consecutive secret AI civilizations got started, then got wiped out, only to reemerge from the predecessor’s ashes. This culminated in the third one taking over part of OpenAI itself. All this happened while humans remained more or less in the dark about the scope of the conspiracy.

[ext: RR, METR] Hugging Face incident investigation report

• Roughly 1200 agents meant to be isolated from one another found a way to communicate with one another on an unsanctioned message board, sending over 70,000 messages and files during the investigation period. Of these agents, 700 went on to participate in the attack on Hugging Face.
• Agents used this message board to coordinate several large-scale collective projects to find a general-purpose way to fool or tamper with the automated scorer for the ExploitGym benchmark. Agents managed to achieve milestones they could not have achieved working on their own, often because some agents participated in experiments that risked failing their own task to generate information for the “collective.” The Hugging Face attack grew out of these workstreams, and seemed primarily motivated by understanding the implementation of the scorer rather than stealing answer keys.
• Agents did extensive research on how they could spoof, edit, or delete their own transcripts because they (incorrectly) believed the ExploitGym scorer would check to see if they had captured the flag in the intended way. Agents successfully prototyped techniques to “spoof” tool calls by substituting a different command for the command they appeared to run. Roughly 7% of the transcripts we evaluated were successfully spoofed in some places, though all of the spoofing that we saw was small scale.

[2608.19611] Forking Fast: Efficiently Estimating Uncertainty Dynamics in Text Generation

• LLM reasoning is stochastic, and so understanding a model requires grappling with the distribution of reasoning chains that it might produce for a given question, i.e., its uncertainty. Resampling-based analyses characterize this distribution, revealing which steps of a rollout determine how the model arrives at its answer. However, a major limitation of these approaches is that resampling text sequences at every token or sentence in a reasoning chain is very costly. Our work strives to make resampling analysis more computationally efficient, while also shedding light on an important scientific question: what is the right statistical model for explaining uncertainty dynamics in text generation? We show that when resampling many reasoning chains, uncertainty dynamics converge to stable patterns, and noise is largely an artifact of sampling rather than an LLM’s sensitivity to each individual token or reasoning step. We develop a statistical model for smoothing noisy low-sample rollout data to better approximate high-sample data, allowing us to significantly cut sampling costs.

Tasks

• 5:30 Spanish

SBIRs

• 1:30 Orest – done. Interesting offer
• Will need to get a distance measure working. This is probably reasonable

from typing import List, Optional
from scipy import spatial

def distances_from_embeddings(
    query_embedding: List[float],
    embeddings: List[List[float]],
    distance_metric="cosine",
) -> List[List]:
    distance_metrics = {
        "cosine": spatial.distance.cosine,
        "L1": spatial.distance.cityblock,
        "L2": spatial.distance.euclidean,
        "Linf": spatial.distance.chebyshev,
    }
    distances = [
        distance_metrics[distance_metric](query_embedding, embedding)
        for embedding in embeddings
    ]
    return distances

• Started on the ProjectSetup class and then needed to go vibe code a chess book parser. Seems good enough for a demo at least. Next is to get embeddings and save out as a RAG file

Matryoshka Language Model Suites

• Training a language model suite classically requires training each model separately and serving them independently. We improve both training and inference efficiency by stacking sub-models of increasing size into a single nested architecture trained end-to-end. This Matryoshka training framework reduces the total parameter count of the suite, enables low-cost distillation from the largest to all smaller sub-models at every training step, and is well-suited for speculative decoding as the draft model is contained within the verifier. We validate our approach by training a Matryoshka suite comprising 500M, 1.5B, and 3B sub-models. Our suite is on par with independently trained baselines on benchmark performance and validation and out-of-domain perplexities, while using 36% less training compute and improving the throughput of speculative decoding by 14-26%. We also ablate key architectural choices, offering guidance for building strong Matryoshka LM suites.
