LLM Consistentie Tester — Gratis online tool

Plak N outputs — meet variantie, gelijkenis, stabiliteit

Plak meerdere LLM-outputs van dezelfde prompt. Meet variantie, Jaccard-gelijkenis, stabiliteitsscore. Detecteer wanneer temperature verlagen.

Workflow: Run your prompt 3-10× at your chosen temperature. Paste each output below. We measure the variance across them.

Frequently Asked Questions

Why test LLM consistency?
For production LLMs, variance is a killer. A prompt that works 9/10 times but fails the 10th is production-fragile. Teams need to know: is the variance acceptable? Should I lower temperature? Is this task fundamentally non-deterministic?
What is Jaccard similarity?
Jaccard = |A ∩ B| / |A ∪ B| for word sets. Value 1.0 = identical words, 0 = no shared words. For most LLM outputs, 0.3-0.6 = semantically similar with different wording, 0.7+ = very close phrasing.
How to improve consistency?
Lower temperature (0.0-0.3 for deterministic tasks). Add more few-shot examples. Use structured output (JSON schema). Pick a lower-creativity model. For truly deterministic tasks consider fine-tuning.

Why Use LLM Consistency Tester?

You should try LLM Consistency Tester for a quick, private way to paste n outputs — measure variance, similarity, stability. Processing happens in your browser and files are never uploaded; the few tools that need an outside service say so on the page.

On the other hand, dedicated APIs or desktop tools suit batch processing better. They also handle server-side automation. For everyday tasks, browser tools offer the best speed, privacy, and convenience.
