We find that Sonnet 3.5 & 4, the models that best maintain accuracy in ciphered reasoning, can reason in well-known ciphers like rot13 and base64 with 45% accuracy drops.
[2510.09714] All Code, No Thought: Current Language Models Struggle to Reason in Ciphered Language
Topological properties of data, such as links, may make it impossible to linearly separate classes using low-dimensional networks, regardless of depth. Even in cases where it is technically possible, such as spirals, it can be very challenging to do so.

When the problem’s conditioning is poor, the optimal 𝛼 α is approximately twice that of gradient descent, and the momentum term is close to 1 1. So set 𝛽 β as close to 1 1 as you can, and then find the highest 𝛼 α which still converges.
Why Momentum Really Works
the “pathological directions” — the eigenspaces which converge the slowest — are also those which are most sensitive to noise!
Why Momentum Really Works
Both GRAM and LoRA isolate capabilities from real-world dual use data. We train an 800M-parameter language model on a combination of general text, code, and scientific papers. We additionally train on data from four dual use domains: virology, cybersecurity, nuclear physics, and specialized code.
Modular Pretraining Enables Access Control
The claim here is that 1bit learning is extremely sample inefficient: there’s no learning happening for partial success, and with long chains of actions, the probability of sampling a success can shrink quickly towards 0 (if this sounds familiar to you, some eminent guy in Deep Learning makes this claim often…).
Just make the straw bigger
Too often, we quickly jump ahead to the new thing, failing to get good enough at the important thing.

within LLMs’ repertoire of vector representations, is there a privileged subset that plays a computational role analogous to the global workspace?
Verbalizable Representations Form a Global Workspace in Language Models
This has a close connection to the exploration-exploitation trade-off: increasing entropy results in more exploration, which can accelerate learning later on. It can also prevent the policy from prematurely converging to a bad local optimum.

We can make meaningful progress on this now because we have systems that implement values well enough to study and test for how well they implement our intent. This is a fundamental change, and understanding it is a prerequisite to our future progress and understanding our risks.

[2506.17209] Fine-Tuning Lowers Safety and Disrupts Evaluation Consistency
Instead of being a perfectionist about the paper, be a perfectionist about writing the paper. Be a perfectionist about identifying good strategies, about abandoning sunk costs, about killing your darlings, about noticing when you're done. Be a perfectionist about wasting no attention. Be a perfectionist about learning from your mistakes. Perfectionism can be a powerful tool, but there's no need to point it at overachieving on metrics you don't care about.

[2506.11613] Model Organisms for Emergent Misalignment
Overly abstract thinking involves relying on g eneralized schemas that are devoid of contextual cues. This can lead decision-makers to apply poorly fi tting mental models, misjudge threats or opportunities as more distant than they are, or assume that others will behave in stereo typical ways. Conversely, overly concrete thinking involves being deeply immersed in the minute details of a speci fi c situation. Such detail-oriented thinking may cause decision-makers to mistakenly miss the bigger picture by overlooking broader trends that unfold over time and multiple locations, leading to choices…

The truth is, we can’t do without ad hominem reasoning, for the simple reason that human knowledge is deeply social. Almost everything we know comes from testimony; only an infinitesimal fraction do we verify ourselves. The rest is, literally, hearsay. No wonder we are so sensitive to the reputation and trustworthiness of our sources.
