Agent EngineeringAre agent harnesses dying? What harness distillation changes
Harness distillation can train general scaffolding into a model. The harness that remains is the part tied to your tools, data, users, and environment. Laurie Voss September 29, 2026 9 min read -
Agent EvaluationJev vs. LLM-as-a-Judge: Accuracy and cost benchmarks
We benchmarked Jev against Claude Opus 5 and GPT-5.6 Terra on accuracy, cost, and latency. Learn how threshold tuning changes hallucination detection. Laurie Voss September 23, 2026 11 min read -
Agent EngineeringTypeSafe’s Jev: Can decision models replace LLM judges?
TypeSafe’s Jev classifies, scores, and routes without generating text — up to hundreds of times cheaper than an LLM judge. What that changes for evals, confidence routing, and… Laurie Voss September 18, 2026 10 min read -
Agent EngineeringAgent cost management is about more than the model
Every LLM call your application makes costs money, and agentic applications make a lot of LLM calls. Arize AX now ships a Cost Agent that reads traces, ranks… Laurie Voss September 1, 2026 8 min read -
Agent EvaluationIs your coding agent uploading all your code?
After Grok Build was caught uploading entire Git repos, we read the privacy docs for Claude Code, Codex, Cursor, GitHub Copilot, and Grok Build to compare what code… Laurie Voss August 20, 2026 7 min read -
Agent EvaluationWhere agent evals are going: Agent-as-a-Judge
Agents changed what failure looks like, and the evaluation layer has to change with them. Why agent-as-a-judge is moving from research paper to production eval stack. Laurie Voss August 19, 2026 8 min read -
Agent EngineeringHow cheap models changed multi-agent economics
Orchestrator-executor just became the smart default for production agents: an expensive model plans, cheap models execute, and cost per completed task decides the roster. Laurie Voss August 7, 2026 8 min read
Don’t ship vibes.
Arize gives AI teams observability and evals to understand and improve agent performance.
