7.2.2. Custom Models

Custom models handle your unique document types when pre-built models don't cover your needs. You label example documents, train a model, and deploy it for extraction.

Model types:

• Template (fixed layout): For forms with consistent structure (same form every time)
• Neural (variable layout): For documents where content moves around (different invoice formats)

Training requirements:

• Minimum 5 labeled documents per model
• Template models train in seconds
• Neural models need more examples (15+) and longer training time

Composed models: Combine multiple custom models into one endpoint. The service automatically routes documents to the right model.

Workflow: Create project → Upload samples → Label fields → Train → Test → Deploy
