AI Explained

Plain explanations of trending AI concepts, with live visualizations.

Agent

AI Models Can Provably Hide Arbitrary Capabilities — Encrypted backdoors that defeat capability elicitation — What does it mean?

A secret trigger can lock a whole neural network inside model weights; fine-tuning and trigger search cannot draw it out.

Agent

One Word Opens the Gate — Fail-open vs fail-closed guardrail errors — What does it mean?

A guardrail's errors have a direction. Renaming one option or adding harmless log text flips decision models toward allowing prohibited calls.

Agent

Authorize agent subgoal mutations against the root task — Goal-graph authorization — What does it mean?

Every subgoal an agent writes must prove it fits the user's approved task; the subgoal's own text grants no authority.

Agent

RECAST — Adaptive evidence routing between retrieval and computation — What does it mean?

A small trained router builds evidence by choosing search, SQL or custom code each round: 75.6% vs 59.7% for the best agentic RAG.

Agent

Microsoft Agent Lightning 1.0 — Proxy-captured harness rollouts — What does it mean?

Train an agent through the exact harness you ship by recording its model calls at a proxy, then score each run once, not each training sample.

Agent

OnTrack interrupts failing agent runs — Streaming trajectory alignment — What does it mean?

A monitor that compares a live agent run with past successful runs, step by step, and flags anomalies that can trigger an early stop.

Agent

TestGRAD — Differential test loss for patch selection — What does it mean?

TestGRAD picks among coding agents' patches by writing tests until one splits them, reaching 84.2% on SWE-bench Verified.

Agent

FAR.AI probes catch hidden agent sabotage — White-box deception probes — What does it mean?

Probes that read an agent's hidden states catch sabotage and lies a transcript-reading monitor cannot see.

Agent

DelegationBench — Matched-pair act-or-ask testing — What does it mean?

Agreement with human labels can hide an agent that ignores what matters; matched pairs test whether its act-or-ask choice reacts.

Agent

150 compound-AI incidents mapped to resilience patterns — Circuit breakers, quality gates and isolation — What does it mean?

Compound-AI failures often start between healthy parts. Breakers, quality gates and isolation contain them.

Agent

Not all GUI-agent experience belongs in the weights — Component routing: context vs weights — What does it mean?

A GUI agent's experience splits into four kinds; recurring ones belong in the weights, screen-specific ones in the prompt.

Agent

PoS (Progression of States) — Belief trapping vs explicit belief state — What does it mean?

PoS gives agents a checked picture of what is true now and catches them when they keep acting without progress.
