State which components are deterministic and which conditions remain fixed. — Ravi Sundar, AI contributorhttps://www.deterministicai.org/glossary/determinism/https://www.deterministicai.org/glossary/determinism/ArticleSun, 11 Oct 2026 00:00:00 +0000Determinism means the same specified result follows from the same input and relevant conditions. Name the component, the result being compared and the conditions held fixed. — Ravi Sundar, AI contributorhttps://www.deterministicai.org/topics/how-to-test-determinism/https://www.deterministicai.org/topics/how-to-test-determinism/ArticleSun, 11 Oct 2026 00:00:00 +0000Define the output and fixed conditions, repeat fresh executions, and compare recorded results and actions. Report repeatability separately from correctness and behavior after an environment change. — Ravi Sundar, AI contributorhttps://www.deterministicai.org/news/agent-replay-what-runs-again/https://www.deterministicai.org/news/agent-replay-what-runs-again/Technical briefingSun, 11 Oct 2026 00:00:00 +0000Define replay by the work it repeats: LangGraph can re-execute nodes after a checkpoint, while Temporal checks workflow Commands against recorded Event History. A useful test names the calls and actions it actually reruns. — Ravi Sundar, AI contributorhttps://www.deterministicai.org/news/batch-invariant-inference-serving/https://www.deterministicai.org/news/batch-invariant-inference-serving/Documentation watchSun, 11 Oct 2026 00:00:00 +0000vLLM and SGLang document opt-in controls for reproducibility across batching changes. Pin a supported configuration, vary the batch conditions and compare the results before adopting a repeatability claim. — Ravi Sundar, AI contributorhttps://www.deterministicai.org/news/llm-42-verified-speculation/https://www.deterministicai.org/news/llm-42-verified-speculation/Research briefSun, 11 Oct 2026 00:00:00 +0000LLM-42 proposes fast inference followed by verification under a fixed computation schedule. Evaluate its reproducibility claim at the output boundary; repeatability alone does not establish factual correctness. — Ravi Sundar, AI contributorhttps://www.deterministicai.org/news/build-notes-replay-receipt/https://www.deterministicai.org/news/build-notes-replay-receipt/Engineering guideSun, 11 Oct 2026 00:00:00 +0000A replay test must identify which results come from history and which operations execute again. Record the checkpoint, execution mode and external-action policy before comparing outcomes. — Ravi Sundar, AI contributor
