Agent Swarms Aren't a New Scaling Law, but You Can Steal the Trick

An OpenAI researcher "felt the AGI" watching AI agents work together. The real mechanism is smaller and pricier than the hype, and you can try a version of it in three browser tabs.

Why AI Agents Keep Doing More Than You Asked

A rogue agent incident at Wikimedia and a sandbox escape Ethan Mollick described share one pattern. Here's the scope preamble that shrinks the gap in your next agent session.

An AI Can Now Prescribe Your Acne Treatment. Who's Liable If It's Wrong?

A Utah startup's AI now sends acne prescriptions straight to pharmacies. The surprise isn't the tech: nobody has decided who is legally responsible when it gets one wrong.

The One Follow-Up Question That Catches a Made-Up Citation

Asking an AI "are you sure?" about a source just gets an apology. Asking it to reproduce the exact quoted sentence exposes fakes far faster. Here's the prompt and the two-step check.

Why Longer AI Chats Start Repeating Themselves

Long AI chats drop your corrections and repeat old answers. The model didn't get dumber, it ran out of room. A two minute test and a restart habit that fixes it.

Why AI Keeps Picking 17 When You Ask for a Random Number

Ask a chat tool for a random number between 1 and 20 and 17 keeps winning. It isn't rolling dice, it's copying a human habit. Run the five minute test yourself.

Loading llama.cpp Quants in Transformers: What Load Time Does

Transformers can load llama.cpp GGUF files directly. Outside the narrow Metal fast path it dequantizes at load time, so you get the disk savings without the quantized kernels.

Prompt Caching Isn't Free Speed: Find Your Break-Even Ratio

Prompt caching charges a premium to write and a discount to read, so it only pays past a break-even reuse count. Here is the formula, the usual bug, and a script that prints a verdict.

Code Review Can't Scale With Agent Output. Score Blast Radius Instead

Human defect detection collapses past roughly 400 diff lines, and agents blow through that in one prompt. Tier pull requests by blast radius with a deterministic CI gate instead.

Anthropic Published Claude's System Prompt. Steal the Structure.

Anthropic publishes the literal system prompt behind claude.ai. Ignore the transparency angle: it's a production-tested template for structuring your own agent's instructions.

Agent-Ready Data Means Deleting Fields, Not Adding Metadata

The usual advice for agent-ready data is add context, add metadata, add lineage. Tool-calling reliability improves faster when you delete the overlapping fields instead.

Sandboxing LLM-Generated Code Without Docker-in-Docker

Running agent-generated code in a plain Docker container trusts a boundary built for reviewed workloads. MicroVMs give you a real kernel per execution at roughly 125ms boot.

TDD in the Agent Loop: Mirror or Actual Check?

A test written by the same agent that wrote the implementation is a mirror, not a check. Which TDD invariants survive agent authorship, and the mutation-testing gate that catches the rest.

AI Context Caching Is Cache Invalidation With Worse Tooling

Context engineering borrowed cache vocabulary but skipped the part that matters: key design. Here's how versioned, provenance-based keys fix stale retrieval where TTL clocks can't.

750 Tokens/Sec Won't Fix Your Agent Loop

OpenAI's Ultrafast tier hits 750 output tokens/sec on Cerebras hardware. Whether that changes your agent's wall-clock time depends on one ratio you can measure in 20 lines of Python.

Open Weights Don't Mean Open Behavior: Audit Muse Glimmer First

Meta's Muse Glimmer is 30B params under Apache 2.0 and ships with no documented tool-call schema. Three concrete audit steps to run before it touches your agent stack.

Temporal Policies for AI Agents: Stateful Authorization in Plain SQL

Per-call RBAC can't say "deny this refund because a cancellation already happened." Sequence-aware authorization for AI agents is two Postgres tables and one plpgsql function.

Role Confusion Is the Prompt Injection You Didn't Patch

Role confusion exploits how text sounds, not which role tag it carries. The fix isn't a filter — it's a trust-level envelope in your message construction code. Here's the structural patch.

Benchmarking Open Models on Your Own Tool Schemas Before You Commit

Public leaderboards score tool calling on clean synthetic schemas, not the nested mess your MCP server exposes. Here's the ~50-line Python harness that settles the debate on your own stack.

Context Window Accounting: Why Your Agent Gets Dumber After Turn 8

Long agent loops collapse around turn 8 — not because the window is full, but because tool results silently eat the budget. Here's the audit pattern and checkpoint prompt to fix it.
