Commercial transition
Previous stateAI Gateway did not expose the newly announced free promotional window and stop-versus-bill model-ID choice for Ling 3.0 Flash Sante.
→New stateThe standard inclusionai/ling-3.0-flash-sante ID is free through 4 October and starts billing after the offer, while inclusionai/ling-3.0-flash-sante-free stops serving at the end instead of billing.
Who is affected
Developers and teams testing or using Ling 3.0 Flash Sante through Vercel AI Gateway, especially workloads that must avoid automatic paid continuation.
Action required
Choose the free-suffixed ID when stop-at-expiry behavior is required, or budget and monitor the standard ID before it begins billing after 4 October.
Evidence boundary
The record covers AI Gateway availability and the two promotional model-ID behaviors only. It does not validate medical outputs, guarantee clinical suitability, waive usage tracking or make the standard ID permanently free.
