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:

  • Spam detection
  • Fraud detection
  • Document classification
  • Defect detection

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.
