Process Reward Agents — When Reasoning Learns to Judge Itself (Before It’s Too Late)
A mechanism-first reading of Process Reward Agents, showing why step-wise online verification matters more than simply adding retrieval to LLM reasoning.

Protocol Over Hype: Why AI Drug Discovery Agents Need Memory, Not Just Models
A mechanism-first reading of CACM, showing why reliable AI drug discovery agents need deterministic protocol audit, grounded diagnosis, and compact corrective memory—not just stronger molecular generators.
Spatial-Gym and the Illusion of Thinking: Why AI Can’t Walk Before It Runs
Spatial-Gym shows why step-by-step AI agents can finish tasks without solving them—and why business evaluation needs logs, verifiers, and constraint-aware benchmarks.
The Ask Gap: Why AI Agents Fail Not Because They Can’t Think — But Because They Don’t Know When to Stop
HiL-Bench shows that production AI agents often fail not from weak capability, but from poor judgment about when to ask humans for missing context.
The Monoculture Trap: When AI Coordinates Too Well
A mechanism-first reading of why LLM agents coordinate brilliantly when sameness is useful, yet struggle when valuable systems need them to stay different.
Dead Weights, Live Signals: When Frozen Models Start Talking
A mechanism-first reading of how frozen language models can be composed through latent-space communication, what the benchmark gains actually support, and where the idea is still fragile.
Phantasia and the Illusion of Safety: When AI Lies Without Looking Wrong
A mechanism-first reading of Phantasia, a context-adaptive backdoor attack showing why plausible multimodal outputs can be more dangerous than obvious failures.
Reading Between the Lines (and the Users): Why Sarcasm Detection Finally Needs Memory
A mechanism-first reading of SinaSarc: why Chinese sarcasm detection improves when models learn not only the sentence, but the user behind it.
Scaling Smarter, Not Larger: Why Your AI Dataset Is Probably Wasting Money
A mechanism-first reading of MOSAIC, showing how scaling-aware data selection turns AI training data from a volume problem into a marginal-utility allocation problem.
Seeing Is Not Solving: Why AI Still Gets Stuck in 3D Worlds
PokeGym shows why embodied VLMs fail less from abstract reasoning limits than from brittle visual-control loops, deadlock recovery, and weak spatial execution.
