LLM Output Determinism Tester

Are your LLM outputs really reproducible? Paste two outputs from the same prompt and measure character/word variance. Most "deterministic" prompts at T=0 still drift 1–10%.

How to use this tool

  1. 1

    Run same prompt twice

    Use temperature=0 with seed if your provider supports it.

  2. 2

    Paste both outputs

    Output 1 and Output 2 below.

  3. 3

    See variance score

    Char + word + length variance + determinism rating.

Frequently Asked Questions

Temperature 0 means deterministic, right?
Nein. Even at T=0, GPU non-determinism, MoE routing, and batched inference cause variance. OpenAI publishes a `seed` parameter but does not guarantee reproducibility. Anthropic does not expose seed.
When does this matter?
Production agents with assertions, evals, regulated industries (legal/medical), reproducible research, structured output (JSON schema validation breaks if output drifts).
What's a good determinism score?
>95% character match = high determinism (likely safe for prod). 80–95% = drift exists, build retries. <80% = your prompt is non-deterministic, redesign.
