How Sebastion AI picks an audit model based on your plan.

Models

Sebastion AI picks the audit model for you based on your plan. There is no model parameter to set. We pick a frontier model that gets security review right and route around it when something better lands.

PlanWhat we run today
FreeA fast frontier model (currently Claude Sonnet 4.6)
ProA higher-reasoning frontier model (currently Claude Opus 4.6)

The exact mix can change with provider availability and pricing. When it changes materially, we'll publish a note on the blog and notify customers directly.

Why we don't expose model selection

Security review is the product. Choosing the model is our job, not yours: we benchmark new releases against our regression suite, route around outages and roll back models that regress on false-positive rates. Letting you pick a model would mean letting you pick a worse audit, so we don't.

If you have a strong opinion on model choice (e.g. data-residency constraints in a specific region), reach out via contact and we'll see what we can do.

If a new model genuinely beats the current one on our regression suite, we switch. You will find out via your audits getting slightly better, not via a newsletter.
