AI Engineering·Aug 6, 2026We Audited Our Own AI Assistant: What a Blended Accuracy Score Hides
We sell AI reliability assessments, so we ran one against our own site assistant and published everything it found. The overall score was a comfortable 82.5%. The one field where a wrong answer costs real money scored 50%. Here is the full result, including the case we deliberately left failing.

Generative AI·Aug 4, 2026Observability Is Not Evaluation: What LLM Tracing Cannot Tell You
Your team installed Langfuse or LangSmith, the dashboards are green, and everyone feels covered. Tracing tells you what the model did. It cannot tell you whether the answer was right, because it has no idea what right looks like. Where the two tools differ, why the gap is structural, and how to use your traces to close it.

Generative AI·Jul 18, 2026Eval Frameworks: How to Swap LLM Models Without Breaking Production
A better model drops every few weeks, and most teams can't upgrade because they can't prove the new one won't break the cases that matter. The fix is an eval harness built on a golden set you own. How to build it, what to grade, and how the model swap becomes a config change instead of a three-week gamble.
