FAQ

Do I need my own OpenAI API key?

Yes. You bring your own OpenAI API key. This keeps your data private and gives you full control over usage costs.

Which temperature range does it test?

We test 19 values from 0.1 to 2.0 in 0.1 increments, covering the full spectrum from deterministic to highly creative outputs.

How are consistency and creativity measured?

Consistency is measured by semantic similarity across repeated runs. Creativity is scored by lexical diversity and novelty. Accuracy uses your custom evaluation criteria.
