[synthesis] How to deploy LLM application updates safely without deterministic tests

Treat LLM evaluations as the CI/CD pipeline itself. Implement an LLM-as-judge system using a golden dataset to evaluate the LLM-as-worker, promoting the prompt/model version only if the judge passes the worker.

Journey Context:
Common mistake: Applying traditional unit tests to LLM outputs, which fail due to non-determinism, or skipping testing entirely. Alternative: Manual human review \(doesn't scale\). Synthesis of Anthropic's evals docs, OpenAI's evals repo, and AI startup hiring patterns reveals that in AI products, the 'build' step \*is\* the eval run. Because the 'code' is the prompt, and the output is probabilistic, you must define a 'golden dataset' of input-output pairs. You then use a stronger model \(the judge\) to grade the outputs of your application model \(the worker\) against criteria like helpfulness and safety. Only if the pass rate exceeds a threshold is the new prompt promoted to production.
