Knowledge that moves
with the pace of AI.

Can a causal graph explain why a reinforcement learning agent acted? ── A preprint proposing CausalXRL, which learns the causal structure behind an agent's decisions and returns explanations at more than one level

Where do AI agents that act before being asked go wrong? ── A preprint introducing HALO, in which experts graded proactive agents' responses in detail and found that premature and excessive interventions caused most rejections

Before running heavy reasoning, let a light model estimate whether it is worth it ── A preprint that formalises a loop in which System-1 screens candidates and System-2 executes them, and ties the possible saving to the density of useful candidates

Does Agent Memory Beat Simply Searching the Raw History? ── Memory Tax, a preprint that compares dedicated memory systems with naive RAG and separates what memory gains from what it loses

Making Professional Tasks Executable Before Training on Them ── WorkFactory, a preprint on planning the information a task needs and repairing defects through trial runs

Can Agents Post-Train a Model Across Several Domains at Once? ── ParetoRSI-Gym, a preprint proposing an environment that varies only the data and measures results in five domains

The file is genuine, yet the model cannot write code ── A preprint that functionally tests quantized LLMs in public registries and reports low-bit failures that calibration can reverse

When AI agents train a model and people grade it, what actually improves? ── A preprint on RSI Arena, a two-stage study in which ten frontier models post-train a language model and then receive human comparison records and votes
