SLNG uses usage-based pricing by default. You pay for the voice workloads you run, such as telephony minutes, speech-to-text, text-to-speech, and model inference. Plans define scale, guarantees, control, and data ownership, not access to features.

Every plan includes access to the same Voice AI Cloud, with all supported models, regions, runtimes, and APIs. SLNG does not gate core capability by plan.

The difference is not capability. Plans vary by scale, execution guarantees, behaviour control, data ownership, integrations, and support.

Usage is billed independently of your plan. You pay for actual voice usage, while plans and add-ons define concurrency, guarantees, and operational certainty.

Concurrency defines how many calls can run at the same time. Additional capacity can be reserved using add-ons, while usage billing stays the same.

Yes. SLNG enforces region and country rules at runtime. Enterprise plans add residency, retention, auditability, and SLA-backed guarantees for regulated workloads.
