AI Explained
Plain explanations of trending AI concepts, with live visualizations.
WebTrap Farm — Paired usability calibration — What does it mean?
A failed attack is only a defense if the agent could do the benign twin of the task. WebTrap Farm scores web agents that way.
ARE-bench — In-progress workspace replay — What does it mean?
Grade agents inside the half-finished project a request came from: models at ~69% on the deliverable alone fall to 28-40%.
MCP servers v2.4.0 — Symlink TOCTOU path confinement — What does it mean?

CARE-PO paper — Task-anchored tool-call budgets — What does it mean?

Dreaming replays transcripts between sessions to fix an agent's notes, build wikis, and keep its startup context small.
Parallel Agent Teams — Many small teams vs one big team — What does it mean?
Ten teams of ten agents beat 100 solo agents and one team of 100: teams raise the mean, and many samples keep the spread.
AMD PrimusClaw — Lease-claimed durable agent runs — What does it mean?
PrimusClaw stores each agent run as a database row under a 45 s lease, so another worker can resume it when the first one dies.
EnvOpt paper — Optimizing the environment, not the harness — What does it mean?
Reorganizing the documents and tools an agent works in cut Haiku 4.5 cost 72.7% on AutomationBench, with no model or harness change.
MCP authorization rewrite — JWT audience, issuer and scope checks — What does it mean?
An MCP server must check that a signed token was issued for it, by one issuer, with the needed scope.
MCP authorization rewrite — Client ID Metadata Documents — What does it mean?
MCP makes a client's own URL its OAuth client ID and deprecates Dynamic Client Registration.
DeepSearch QRAE — Attention-entropy evidence scoring — What does it mean?
Score retrieved chunks with paired-prefill attention; keep the relevant ones, cache the uncertain.
