HephaKnot is an applied AI research lab. We test models in the conditions they run in, check the data behind them, and keep the evidence for each result.

Model robustness
When do models become unreliable?
Data quality
What does the data leave out?
Evaluation & assurance
What evidence supports a deployment decision?

Our focus

A model can pass a benchmark. The world keeps changing.

Different weather. Missing examples. An unfamiliar document. We investigate how changes in data and conditions affect model behaviour, and what evidence helps us understand its limits.
