Prompts vs Predictions
Generative AI writes answers. Applications need decisions.
LLMs are excellent for generating text and reasoning through prompts. But applications often need to make the same decision thousands or millions of times:
These tasks require
Consistent predictions
Same input, same output — every time
Confidence scores
Know how certain the model is
Fast inference
Millisecond response times at scale
Models trained on your examples
Custom to your data, not generic
Monitoring and Retraining
When data changes, models adapt
Nyckel builds models designed for reliable predictions.
