Adaptive execution

Every turn shouldn't cost same as the hardest one

"Yes." "Can you hold?" "Thanks, that's everything." Each of those costs the same as a question that actually needs thinking about. Then there's distance. Most model providers run in the US. If your caller is in Mumbai, their voice crosses an ocean and comes back before they hear a word.

Capabilities

Hear it right the first time

Real calls have background noise, people talking over each other, and more than one language in the same sentence. We clean the signal before your transcription model ever sees it.

Does my voice AI data stay in-region?

Yes. Audio processed in a region stays in that region. Every call is logged with region, provider, model, and timestamp. You swap your base URL to the region of your choice.

How does regional compute reduce voice AI latency?

A voice call from Mumbai hitting US servers adds 200ms+ of network round-trip before the model starts processing. When STT, LLM, and TTS all run in the same region as your caller, that round-trip disappears. Observed result: ~39% less turn latency in production.

What is the SLNG Execution layer?

The infrastructure between your orchestrator and your models. It routes each call to the right model, caches repeated patterns, redacts PII, cancels noise, and logs everything: cost, latency, region, provider, per step. You keep your existing code. SLNG handles the layer underneath.

What does "per agent minute" mean?

Agent minute is the length of the call, not the amount of audio processed. A 3-minute call is 3 agent minutes regardless of how much silence or overlap it contains.

How is SLNG different from calling voice AI providers directly?

When you call voice models or LLM directly, you manage routing, failover, cost, and compliance yourself. SLNG sits between your orchestrator and your providers, adding per-turn model selection, smart caching, PII redaction, and regional compute. Your providers stay the same. Your cost and latency go down.

What voice AI models does SLNG support?

30+ models across STT, LLM, and TTS, including Deepgram, Whisper, OpenAI, Anthropic, Rime, Cartesia, and ElevenLabs. Sovereign-hosted models run on SLNG's own in-region compute. BYOK is the default - bring your existing provider keys and contracts.

How is SLNG priced?

US$ 0.001 per agent minute for the Execution layer. Same price as every other region. STT and TTS add-ons are each US$ 0.003 per agent minute with model costs included. No contracts, no minimums, no regional surcharges.

Does SLNG cost more in certain regions?

No. US$ 0.001 per agent minute for the Execution layer in every region. STT and TTS add-ons are each + US$ 0.003. No regional surcharges. No volume tiers.
