Overview
What are model presets?
Model presets are built-in compartmental epidemic models that you can use without defining compartments or transitions yourself. Each preset comes with a set of compartments, default parameters, and transition rules.
You can list all available presets:

Available presets
| Preset | Compartments | Use when |
|---|---|---|
| SIR | S, I, R | You want the simplest possible epidemic model with permanent immunity. |
| SEIR | S, E, I, R | You need a latent (exposed-but-not-yet-infectious) period before infectiousness. |
| SIS | S, I | Recovered individuals return to the susceptible pool with no lasting immunity (e.g. many bacterial infections). |
| V-SEIHR | 10 (S/E/I/H/R × unvaccinated/vaccinated) | You want SEIR with explicit hospitalization, a vaccinated branch, and a vaccination rollout via the vaccination block. |
If none of these fit, you can declare compartments and transitions yourself. See Custom Models.
