An undergraduate researcher identifies and solves a critical optimization pathology in multi-timescale Actor-Critic architectures where temporal attention mechanisms exploit policy gradients ('Surrogate Objective Hacking') or collapse to short-horizon policies. The proposed solution decouples the Actor from multi-timescale Critic representations, forcing robust auxiliary learning while isolating policy updates to long-term advantages, demonstrated via a minimal PyTorch implementation.

An engineer built an open-source benchmark that evaluates frontier LLMs (GPT-5.3, Claude Opus 4.6, KIMI K2) on political stance using a 2D compass across 98 structured questions, revealing critical insights: refusal behavior itself is a measurable political signal, opt-out options dramatically change model outputs (Claude flipped quadrants when given permission to decline), and different models show distinct censorship patterns (KIMI blocks geopolitical content via API errors, GPT opts out universally when allowed). The repo is directly runnable on any model with an API.
