Human Feedback and Annotation Queues for LLMs

## TL;DR

Human feedback and annotation queues route model outputs, traces, or comparisons to reviewers so LLM systems can collect structured quality signals.

## Core Explanation

Automated evaluators are useful, but human review remains important for ambiguous quality, policy, style, domain correctness, and user trust. Annotation queues turn review into an operational workflow: select runs, assign reviewers, apply rubrics, record feedback, and convert examples into datasets.

For production LLM systems, the value is not just the label. The queue records which cases were reviewed, by whom, under what rubric, and whether the feedback should become a regression test, training example, or product issue.

- LangSmith documentation says pairwise annotation queues present two runs side-by-side so reviewers can decide which output is better or whether they are equivalent. ([source](https://docs.langchain.com/langsmith/annotation-queues))
