Fastino provides APIs for specialized inference and model training. Use GLiDE for classification, routing, and scoring with calibrated probabilities, or GLiNER for span-level extraction. With the Training API, you can run managed training, run interactive training, or delegate the training lifecycle to private-access Auto Train.

Quickstart: run inference and training

Make your first GLiDE decision call, then create a decoder training job.

​

Inference

  • GLiDE for decisions: classification, routing, and scoring with calibrated probabilities instead of generated text.
  • GLiNER-2.5-Decide for English classification: intent, routing, sentiment, priority, moderation, and ordinal scoring.
  • GLiNER 2.5 Multilingual for multilingual structured extraction.
  • GLiNER2 and GLiGuard for entity extraction, classification, structured data, safety, and PII workflows.
  • Nemotron 3.5 Super VL for general-purpose inference.
  • Nemotron 3.5 Lightning in general-purpose, Healthcare, and Finance variants.
