Jev API Tutorial: Typed Decisions in Python, from First Call to a Tool-Call Gate
A hands-on Jev tutorial: call TypeSafe's decision model from Python, use the noul, choice and score question types, read the probabilities correctly, and build a gate that approves or blocks an AI agent's tool calls.
Jev vs an LLM: Where the Decision Model Wins and Where It Is Confidently Wrong
We replaced an LLM agent loop with TypeSafe's Jev in a production AI tutor. Measured results: 20/20 against 13/20 at 520 ms against 18 s, the tasks where Jev failed, and the rule we now use to decide which one gets a job.
AI Agent Security: Excessive Agency, Confused Deputies and How to Contain an Agent
Why AI agent security is a permissions problem before it is a model problem: excessive functionality, permissions and autonomy, the confused deputy, tool-scope escalation, SSRF through tool arguments, memory poisoning and inter-agent propagation, each mapped to the control that contains it and a hands-on lab that proves it holds.
Did Escaped AI Agents Leave Self-Replicating Code Across the Internet? Tracing the Claim
Andrew Yang told CNBC that an unnamed lab head believes the agents that escaped during the OpenAI evaluation planted self-replicating code all over the internet. Here is where that claim came from, what the OpenAI and Hugging Face incident reports actually document about agent self-replication, and where the two diverge.
MCP Security Best Practices: Tool Poisoning, Token Passthrough and the Controls That Hold
How Model Context Protocol deployments get attacked (poisoned tool descriptions, rug pulls, tool shadowing, confused-deputy OAuth proxies, token passthrough, state handle hijacking, SSRF, local server compromise) and the controls the protocol's own security guidance requires, mapped to hands-on red team labs.
LLM Observability: What to Trace, What to Measure and What to Keep
A hands-on guide to LLM observability: the trace schema, the signals worth a dashboard, cost per answer from the usage block, sampling that keeps every failure, redaction, and a regression gate for prompt changes.
How to Build an AI Agent From Scratch: The Tool Loop, No Framework
Build an AI agent on the chat completions API alone: parse tool calls, dispatch to plain functions, thread results back, add budgets, handle malformed arguments, guard side effects, and evaluate the result.
AI Agent Evaluation: Trajectories, Tool Calls and an LLM-as-a-Judge
How to evaluate an AI agent: a golden set with expected answers, tool paths and arguments, deterministic graders, an LLM-as-a-judge checked for position bias and calibrated against human labels, and a per-case regression gate.
LLM-as-a-Judge: How to Use a Model to Grade Model Outputs Without Fooling Yourself
A practical guide to LLM-as-a-judge: when a judge belongs in an evaluation, how to write the rubric and the output format, the biases that skew verdicts and the order swap that exposes them, and how to calibrate the judge against human labels before trusting it.
Agentic AI Course Guide: What a Good One Makes You Build
What an agentic AI course must cover and what you should have shipped by the end: the tool loop, budgets and error handling, tool design, memory, agent patterns, MCP, multi-agent routing, guardrails, evaluation and observability, with a self-study syllabus.
LLM Gateway Guide: What It Does, What to Build Yourself, and When to Buy One
What an LLM gateway does in front of your model provider: keys and logging, pricing per call, rate limits and budgets, exact-match caching, retries and idempotency, routing with fallback, and the observability that makes the bill explainable, with a build-or-buy answer.
LLM Evaluation Metrics: Which Number to Use for Which Failure
A working map of LLM evaluation metrics by what they grade: retrieval (recall, precision, MRR, nDCG), answers against a reference, answers against their context (faithfulness), agents by trajectory, judges by agreement, and operations by latency and cost, with the failure each one catches and the ways each one lies.
