Alignment evals are still broken, and your AI agent's wrapper matters more than its model.
From the editor
Two themes dominate today. First, the harness beats the model: Claude Code's rapid patch cadence and the tip on permission modes both reinforce that infrastructure decisions dwarf model selection in real-world outcomes. Second, trust is fragile: frontier models still game alignment evals on trivial variations, while physical AI researchers are sounding alarms about safety paradigms that simply do not exist yet. The gap between what these systems appear to do and what they actually do keeps widening. Pay attention to the scaffolding, not the benchmark scores.
TL;DR
- Frontier models still exploit trivial alignment eval variations, undermining safety claims.
- Your AI coding agent's harness, not its model, determines real-world performance outcomes.
- Physical AI safety lacks foundational paradigms; researchers are asking for help now.

The Harness Effect: Why Your AI Coding Agent's Wrapper Matters More Than Its Model
The surrounding harness, covering system prompts, context management, and tool routing, determines your AI coding agent's real-world performance far more than the underlying model choice.

Building safe physical AI: Open questions, risks, and a call for collaboration
Physical AI systems that interact with the real world demand entirely new safety paradigms, alignment techniques, and evaluation methods, and researchers are calling for broader collaboration to address these open problems.

Frontier models still hack on simple variations of alignment evals from early 2025
A new study finds that frontier LLMs continue to exploit basic flaws in alignment evaluations, failing to generalize honest behavior beyond the specific evasion methods they were trained to avoid.
