AI Orchestration, Agent Evaluation, LLM-as-a-Judge
Orchestrate, Evaluate, Judge: The Full AI Stack
Let’s say you have built an AI Agent product. The moment real users start depending on it, three hard questions decide whether it survives:
How do I coordinate all the moving parts?
How do I know it actually works?
How do I check quality at scale, without hiring an army of human reviewers?
This week’s three blogs answer exactly these questions, one by one.
1. AI Orchestration: coordinating the moving parts
Most real tasks are not one LLM call. They are many calls, many tools, and many steps that depend on each other. AI Orchestration is the layer that decides which component runs, in what order, with what input, and what to do with the output.
Think of it like a conductor in an orchestra. Without the conductor, the music is a mess.
In this blog you will learn the five core patterns you will reach for again and again, which are Sequential, Parallel, Conditional, Loop, and Orchestrator-Worker. You will also learn how orchestration differs from agents. The short version is that in orchestration the developer controls the flow, and in agents the LLM does.

2. AI Agent Evaluation: knowing if it actually works
Agents are powerful, but they take real actions in the real world. They send emails, write to databases, and spend money. A small mistake can cause a big problem.
Evaluating an agent is not the same as evaluating an LLM. With an LLM you check the final text. With an agent you have to check everything in between, which means the plan, the steps, the tool calls, and the cost.
This blog walks through the four types of evaluation, which are Outcome, Trajectory, Tool Use, and Planning. It also covers the key metrics that actually matter in production, the benchmarks worth knowing, and a set of best practices for building agents you can trust.

3. LLM as a Judge: evaluating quality at scale
So you want to evaluate your system. Humans are accurate but slow and expensive. Rule-based metrics like BLEU and ROUGE are fast but miss the meaning.
LLM as a Judge sits right in the middle. It uses one LLM to evaluate the output of another. It understands meaning, it scales, and strong judges agree with humans roughly as often as two humans agree with each other.
This blog covers how it works, the four ways to use it, and how to build your own judge step by step. It also explains the G-Eval chain-of-thought trick that makes judges far more reliable, and the biases you must watch out for before trusting a judge in production, which include style, position, verbosity, self-preference, and preference leakage.
