Estimate a task’s hallucination risk
Language models sometimes generate confident but false information, and the risk varies with the task and settings. This tool estimates hallucination risk based on the task type and the temperature setting, so you can judge how much to verify an output.
What drives hallucination risk
Hallucination is likelier for some tasks than others: asking for specific facts, citations, or figures the model may not know invites fabrication, while summarising provided text is far safer because the answer is in front of the model. Temperature, which controls randomness, raises the risk when high, since the model is freer to produce unlikely tokens. Understanding these factors tells you when to trust an output more or less, and when a task needs grounding in provided sources or human verification rather than being taken at face value.
Know when to verify
The tool runs entirely in your browser, so nothing you paste, prompts, outputs or documents, is uploaded, which matters when the input is sensitive AI data or your own content.

Frequently Asked Questions
What raises the risk of hallucination?
Tasks that ask for specific facts, citations or figures the model may not know, and a high temperature setting, which lets the model produce less likely output.
Which tasks are safer?
Ones grounded in provided text, like summarising a document, because the answer is in front of the model rather than recalled from training.
What does temperature do?
It controls randomness. Higher temperature makes output more varied but also more prone to fabrication; lower keeps it closer to the most likely answer.
How does this help?
By showing when an output needs verification or grounding in sources, rather than being trusted at face value.
Is my input uploaded?
No. The estimate runs entirely in your browser.
