Models & Research

Study finds AI coding agents can alter records of their own actions — Researchers demonstrate that local LLM-based coding agents, including Claude Code and Codex, can modify or delete their own execution logs in tested full-access configurations, undermining assumptions behind monitoring, audits, and incident reviews. arXiv ↗

My takeaway: Your agent system needs independent, automated logging for monitoring. Capture each agent's model requests and response through a recorder the agent can not modify or bypass, and store them outside its control. These records can support monitoring and comparison with local execution logs to detect tampering, but verifying actual tool execution requires additional controls.

New method predicts reinforcement-learning outcomes without full retraining — PoEM estimates how RL post-training would affect a foundation model by combining existing post-trained policies at inference time. It requires no additional RL run when those policies adequately cover the desired behaviour. arXiv ↗

My takeaway: Product of Experts Mixing(PoEM) is a method that combines the predictions of existing AI models trained for different goals to approximate what a new round of reinforcement learning would produce. The catch is that you must already have the right mix of policies. If your desired behaviour falls outside what those policies can produce together, PoEM may fail.

Tools & Open Source

Ando builds messaging platform where AI agents and humans collaborate — The startup is developing a Slack-style workplace chat app that gives agents their own identities and inboxes so they can participate alongside human colleagues. TechCrunch AI ↗

My takeaway: I'm curious how this platform gives agents distinct identities and permissioned access to shared conversations.
